Formation or presence of a blood clot (THROMBUS) in the LATERAL SINUSES. This condition is often associated with ear infections (OTITIS MEDIA or MASTOIDITIS) without antibiotic treatment. In developed nations, lateral sinus thrombosis can result from CRANIOCEREBRAL TRAUMA; BRAIN NEOPLASMS; NEUROSURGICAL PROCEDURES; THROMBOPHILIA; and other conditions. Clinical features include HEADACHE; VERTIGO; and increased intracranial pressure.
Formation or presence of a blood clot (THROMBUS) in the CRANIAL SINUSES, large endothelium-lined venous channels situated within the SKULL. Intracranial sinuses, also called cranial venous sinuses, include the superior sagittal, cavernous, lateral, petrous sinuses, and many others. Cranial sinus thrombosis can lead to severe HEADACHE; SEIZURE; and other neurological defects.
Large endothelium-lined venous channels situated between the two layers of DURA MATER, the endosteal and the meningeal layers. They are devoid of valves and are parts of the venous system of dura mater. Major cranial sinuses include a postero-superior group (such as superior sagittal, inferior sagittal, straight, transverse, and occipital) and an antero-inferior group (such as cavernous, petrosal, and basilar plexus).
Formation or presence of a blood clot (THROMBUS) in the SUPERIOR SAGITTAL SINUS or the inferior sagittal sinus. Sagittal sinus thrombosis can result from infections, hematological disorders, CRANIOCEREBRAL TRAUMA; and NEUROSURGICAL PROCEDURES. Clinical features are primarily related to the increased intracranial pressure causing HEADACHE; NAUSEA; and VOMITING. Severe cases can evolve to SEIZURES or COMA.
Formation or presence of a blood clot (THROMBUS) in the CAVERNOUS SINUS of the brain. Infections of the paranasal sinuses and adjacent structures, CRANIOCEREBRAL TRAUMA, and THROMBOPHILIA are associated conditions. Clinical manifestations include dysfunction of cranial nerves III, IV, V, and VI, marked periorbital swelling, chemosis, fever, and visual loss.

Inflammation of the honeycomb-like MASTOID BONE in the skull just behind the ear. It is usually a complication of OTITIS MEDIA.
Formation or presence of a blood clot (THROMBUS) in a blood vessel within the SKULL. Intracranial thrombosis can lead to thrombotic occlusions and BRAIN INFARCTION. The majority of the thrombotic occlusions are associated with ATHEROSCLEROSIS.

Mastoid air sinus abnormalities associated with lateral venous sinus thrombosis: cause or consequence? (1/10)

BACKGROUND: Mastoiditis is a known cause of lateral venous sinus thrombosis (LST). We have encountered patients with LST associated with mastoid abnormality on MRI without any clinical signs of infection; the significance of these abnormalities is uncertain. This study examines the relationship of LST and mastoid air sinus abnormalities systematically. SUMMARY OF REPORT: We performed a retrospective clinical and radiological review of a series of 26 patients with cerebral venous thrombosis. Mastoid abnormalities were detected ipsilateral to 9 of 23 thrombosed lateral sinuses (39%) and 0 of 29 unaffected lateral sinuses (P<0.001). No patient had clinical evidence of mastoiditis. Eight of 9 patients with mastoid abnormalities were treated without antibiotics; all made uneventful clinical recoveries. Repeated MRI in 1 patient revealed reversal of the mastoid changes. CONCLUSIONS: The mastoid changes observed are likely to be due to venous congestion as a consequence of LST, not mastoiditis.  (+info)

MR venography in idiopathic intracranial hypertension: unappreciated and misunderstood. (2/10)

BACKGROUND: Venous sinus disease must be excluded before diagnosing idiopathic intracranial hypertension but is found only rarely in typical cases. Magnetic resonance venography (MRV) is the technique of choice for investigating this, and provides images that are diagnostic and easy to interpret. However, recent work using more invasive techniques has documented pressure gradients and stenoses in the lateral venous sinuses in many cases of idiopathic intracranial hypertension. OBJECTIVE: To examine the reason for this discrepancy and to establish whether there are characteristic appearances on MRV in idiopathic intracranial hypertension that are routinely overlooked in clinical practice. METHODS: MRVs from 20 patients with idiopathic intracranial hypertension were reviewed, unblinded, by two neuroradiologists, and their appearances rated for focal narrowings and signal gaps. A control group of 40 asymptomatic volunteers, matched for age and sex with the patient group, was recruited prospectively for MRV, and their scans rated in the same way. RESULTS: The lateral sinuses presented a range of appearances with quite different distributions in the two groups (p<0.001). Bilateral lateral sinus flow gaps were seen in 13 of 20 patients with idiopathic intracranial hypertension and in none of 40 controls. CONCLUSIONS: A historical failure to use normal healthy controls to establish the boundaries between imaging artefact, normal anatomical variant, and disease means that the pathological significance of the different appearances of the lateral sinuses on MRV has not so far been appreciated.  (+info)

Lateral sinus thrombosis. (3/10)

We describe four cases of lateral sinus thrombosis secondary to otitis media. They presented with low-grade fever, headache, nausea, vomiting and ear discharge. One patient had facial nerve palsy. CT scan was helpful in managing these patients. They were treated with antibiotics followed by surgery. Two patients had intracranial abscesses and were treated accordingly.  (+info)

Lateral sinus thrombosis as a complication of acute mastoiditis. (4/10)

Lateral sinus thrombosis is a rare complication of middle ear diseases: in children, it is usually related to acute otitis media, but it is also found in adults with chronic otitis. It was more frequent in the pre-antibiotic era and mortality was high. The Authors present a paediatric case of lateral sinus thrombosis in which they describe the clinical approach and related literature.  (+info)

Cortical subarachnoid hemorrhage caused by cerebral venous thrombosis. (8/10)

Patients with non-traumatic, non-aneurysmal, and non-perimesencephalic subarachnoid hemorrhage (SAH) tend to have clots circumscribed along the cortical convexity, a condition referred to as acute cortical SAH. Cerebral venous thrombosis (CVT) is a potential cause of cortical SAH. The study tried to establish the diagnosis and management of cortical SAH caused by CVT. Retrospective review of 145 patients with non-traumatic SAH identified 15 patients with no ruptured aneurysm. Clinical features were investigated with a specific focus on patients with SAH caused by CVT. Eight of the 15 patients had perimesencephalic SAH, and 7 had cortical SAH. SAH caused by CVT was diagnosed in 4 of the 7 patients with cortical SAH. The cortical SAH involved the unilateral convexity or sylvian cistern and spared the basal cistern on computed tomography in all 4 patients. CVT occurred in the transverse sinus and cortical vein (1 patient), insular vein (1 patient), and cortical vein (2 patients). Identification of thrombosed veins or sinuses was established directly by T(2)*-weighted and diffusion-weighted magnetic resonance (MR) imaging in the acute stage and diffusion-weighted and T(1)-weighted MR imaging in the subacute stage. All patients had cortical swelling without findings of venous hemorrhagic infarction on T(2)*-weighted MR imaging. None of the 4 patients received active treatment, and all had favorable outcomes. CVT in patients with non-traumatic cortical SAH should be first excluded as a potential hemorrhagic cause by MR imaging for thrombosed veins or sinuses before initiating antifibrinolytic therapy.  (+info)

Lateral sinus thrombosis, also known as sigmoid sinus thrombosis, is a medical condition characterized by the formation of a blood clot (thrombus) in the lateral or sigmoid sinus, which are venous structures located in the skull that help drain blood from the brain.

The lateral sinuses are situated near the mastoid process of the temporal bone and can become thrombosed due to various reasons such as infection (often associated with ear or mastoid infections), trauma, tumors, or other underlying medical conditions that increase the risk of blood clot formation.

Symptoms of lateral sinus thrombosis may include headache, fever, neck stiffness, altered mental status, and signs of increased intracranial pressure such as papilledema (swelling of the optic nerve disc). Diagnosis is typically made with the help of imaging studies like CT or MRI scans, and treatment often involves anticoagulation therapy to prevent clot expansion and potential complications. In some cases, surgical intervention may be necessary to remove the clot or manage any underlying conditions.

Intracranial sinus thrombosis is a medical condition characterized by the formation of a blood clot (thrombus) within the intracranial venous sinuses, which are responsible for draining blood from the brain. The condition can lead to various neurological symptoms and complications, such as increased intracranial pressure, headaches, seizures, visual disturbances, and altered consciousness. Intracranial sinus thrombosis may result from various factors, including hypercoagulable states, infections, trauma, and malignancies. Immediate medical attention is necessary for proper diagnosis and treatment to prevent potential long-term neurological damage or even death.

Cranial sinuses are a part of the venous system in the human head. They are air-filled spaces located within the skull and are named according to their location. The cranial sinuses include:

1. Superior sagittal sinus: It runs along the top of the brain, inside the skull, and drains blood from the scalp and the veins of the brain.
2. Inferior sagittal sinus: It runs along the bottom of the brain and drains into the straight sinus.
3. Straight sinus: It is located at the back of the brain and receives blood from the inferior sagittal sinus and great cerebral vein.
4. Occipital sinuses: They are located at the back of the head and drain blood from the scalp and skull.
5. Cavernous sinuses: They are located on each side of the brain, near the temple, and receive blood from the eye and surrounding areas.
6. Sphenoparietal sinus: It is a small sinus that drains blood from the front part of the brain into the cavernous sinus.
7. Petrosquamosal sinuses: They are located near the ear and drain blood from the scalp and skull.

The cranial sinuses play an essential role in draining blood from the brain and protecting it from injury.

Sagittal sinus thrombosis is a medical condition that refers to the formation of a blood clot (thrombus) in the sagittal sinus, which is a venous structure located in the brain. The sagittal sinus runs along the midline of the brain and receives blood from the superficial veins of the brain.

Sagittal sinus thrombosis can occur as a result of various conditions, such as head trauma, infection, cancer, or certain medical disorders that cause hypercoagulability (an increased tendency to form blood clots). The formation of a blood clot in the sagittal sinus can obstruct the flow of blood from the brain, leading to symptoms such as headache, seizures, altered consciousness, and focal neurological deficits.

Diagnosis of sagittal sinus thrombosis typically involves imaging studies such as computed tomography (CT) or magnetic resonance imaging (MRI) scans, which can show the presence of a blood clot in the sagittal sinus. Treatment may involve administering anticoagulant medications to prevent further growth of the blood clot and reduce the risk of complications such as pulmonary embolism or cerebral infarction. In some cases, surgical intervention may be necessary to remove the blood clot or alleviate pressure on the brain.

Cavernous sinus thrombosis is a medical condition that refers to the formation of a blood clot (thrombus) in the cavernous sinuses, which are located near the base of the brain and are important for draining blood from the face and brain. This condition can occur as a complication of an infection in the facial area or sinuses, or it can be associated with other medical conditions such as cancer or trauma.

Symptoms of cavernous sinus thrombosis may include headache, fever, eye pain, swelling or bulging of the eyes, double vision, and decreased vision. If left untreated, this condition can lead to serious complications such as meningitis, brain abscess, or even death. Treatment typically involves administering antibiotics to treat any underlying infection and anticoagulants to prevent further clot formation. In some cases, surgery may be necessary to remove the clot.

Mastoiditis is a medical condition characterized by an infection and inflammation of the mastoid process, which is the bony prominence located behind the ear. The mastoid process contains air cells that are connected to the middle ear, and an infection in the middle ear (otitis media) can spread to the mastoid process, resulting in mastoiditis.

The symptoms of mastoiditis may include:

* Pain and tenderness behind the ear
* Swelling or redness of the skin behind the ear
* Ear drainage or discharge
* Fever and headache
* Hearing loss or difficulty hearing

Mastoiditis is a serious condition that requires prompt medical attention. Treatment typically involves antibiotics to eliminate the infection, as well as possible surgical intervention if the infection does not respond to medication or if it has caused significant damage to the mastoid process. If left untreated, mastoiditis can lead to complications such as meningitis, brain abscess, or even death.

Intracranial thrombosis refers to the formation of a blood clot (thrombus) within the intracranial vessels, which supply blood to the brain. This condition can occur in any of the cerebral arteries or veins and can lead to serious complications such as ischemic stroke, transient ischemic attack (TIA), or venous sinus thrombosis.

The formation of an intracranial thrombus can be caused by various factors, including atherosclerosis, cardiac embolism, vasculitis, sickle cell disease, hypercoagulable states, and head trauma. Symptoms may vary depending on the location and extent of the thrombosis but often include sudden onset of headache, weakness or numbness in the face or limbs, difficulty speaking or understanding speech, vision changes, and loss of balance or coordination.

Diagnosis of intracranial thrombosis typically involves imaging studies such as computed tomography (CT) angiography, magnetic resonance angiography (MRA), or digital subtraction angiography (DSA). Treatment options may include anticoagulation therapy, thrombolysis, endovascular intervention, or surgical intervention, depending on the underlying cause and severity of the condition.
