Neurofibromatoses
Pulmonary hypertension secondary to neurofibromatosis: intimal fibrosis versus thromboembolism. (1/78)
Neurofibromatosis has been known to involve blood vessels throughout the body. Pulmonary involvement with interstitial fibrosing alveolitis has been described but no case of pulmonary vascular involvement has been reported to date. A 51 year old patient with cutaneous neurofibromatosis is described who presented with severe pulmonary hypertension and radiographic, scintigraphic, and angiographic evidence of chronic thromboembolic pulmonary hypertension. Severe intimal fibrosis consistent with vascular involvement with neurofibromatosis was found on endarterectomy with no evidence of pulmonary thromboembolism. Neurofibromatosis of pulmonary arteries should be considered as a possible cause of pulmonary hypertension. (+info)Midline and far lateral approaches to foramen magnum lesions. (2/78)
Twenty patients with foramen magnum lesions were operated upon in the last 5 years at Postgraduate Institute of Medical Education and Research, Chandigarh. The common presenting features were quadriparesis, quadriplegia, diminished sensations, neck pain and respiratory insufficiency. The lesions encountered were meningiomas, neurofibromas, posterior inferior cerebellar artery aneurysms, neurenteric cyst and chordoma. Patients with posterior or posterolaterally placed lesions were operated by the midline posterior approach while those with anterior or anterolateral lesions were managed by the far lateral approach. All mass lesions were excised completely and the aneurysms were clipped. Seventeen patients made good neurological recovery while three died. The latter three patients presented very late. The merits of various surgical approaches to the foramen magnum are discussed. (+info)Segmental neurofibromatosis is caused by somatic mutation of the neurofibromatosis type 1 (NF1) gene. (3/78)
Segmental neurofibromatosis (NF) is generally thought to result from a postzygotic NF1 (neurofibromatosis type 1) gene mutation. However, this has not yet been demonstrated at the molecular level. Using fluorescence in situ hybridisation (FISH) we identified an NF1 microdeletion in a patient with segmental NF in whom cafe-au-lait spots and freckles are limited to a single body region. The mutant allele was present in a mosaic pattern in cultured fibroblasts from a cafe-au-lait spot lesion, but was absent in fibroblasts from normal skin as well as in peripheral blood leukocytes. These findings prove the hypothesis that the molecular basis of segmental cutaneous NF is a mutation in the NF1 gene and that the regional distribution of manifestations reflects different cell clones, commensurate with the concept of somatic mosaicism. (+info)Ruptured internal carotid aneurysm resulting from neurofibromatosis: treatment with intraluminal stent graft. (4/78)
PURPOSE: This report shows a method of treatment for life-threatening hemorrhage due to rupture of an aneurysm in the cervical internal carotid artery caused by neurofibromatosis. METHODS: Ten days after delivery of healthy twins, a 28-year-old woman with known neurofibromatosis had sudden massive swelling in the left neck. After initial tracheostomy, angiography confirmed rupture of the mid cervical internal carotid artery as well as contribution to the resultant pseudoaneurysm from external carotid branches. Treatment began with coil embolization of the external carotid branches. The internal carotid lesion, a defect approximately 1 cm in length, was then closed through use of two stent grafts, each made from Palmaz stents and 3-mm polytetrafluorethylene grafts predilated to 6 mm. The neck hematoma was then evacuated surgically. RESULTS: Completion angiography and computed tomographic scanning confirmed control of the hemorrhage. The patient survived neurologically intact with the exception of cranial nerve deficits caused by the hemorrhage. The tracheostomy tube was removed 3 weeks postoperatively. Follow-up computed tomographic scanning showed a gradual decrease in the size of the cervical soft tissue and no recurrent aneurysm. CONCLUSION: Neurofibromatosis is a rare cause of aneurysmal degeneration of blood vessels. Repair of a ruptured cervical internal carotid artery aneurysm, though feasible, is difficult with stent grafts; however, this is a better option than surgical intervention in inaccessible vessels. (+info)Neurofibromatosis-Noonan syndrome or LEOPARD Syndrome? A clinical dilemma. (5/78)
Neurofibromatosis (NF), Noonan syndrome (NS), and LEOPARD syndrome are all autosomal dominant conditions, each being a distinct clinical entity by itself. Rarely, one encounters cases with features of NF and NS and is termed as the 'Neurofibromatosis-Noonan syndrome' (NF-NS). The authors report a clinical dilemma with major clinical features of the NF-NS syndrome and LEOPARD syndrome co-existing in the same patient. Also, features of Noonan syndrome and LEOPARD syndrome are compared with the case reported. (+info)Neurofibromatosis: clinical presentations and anaesthetic implications. (6/78)
The neurofibromatoses are autosomal dominant diseases that have widespread effects on ectodermal and mesodermal tissue. The commonest member of the group is neurofibromatosis type 1 (NF1) which varies in severity but which can affect all physiological systems. Neurofibromas are the characteristic lesions of the condition and not only occur in the neuraxis but may also be found in the oropharnyx and larynx; these may produce difficulties with laryngoscopy and tracheal intubation. Pulmonary pathology includes pulmonary fibrosis and cystic lung disease. The cardiovascular manifestations of NF1 include hypertension, which may be associated with phaeochromocytoma or renal artery stenosis. Neurofibromas may also affect the gastrointestinal tract and carcinoid tumours may be found in the duodenum. This review documents the aetiology and clinical manifestations of the neurofibromatoses and discusses their relevance to the anaesthetist. (+info)Spinal neurofibromatosis without cafe-au-lait macules in two families with null mutations of the NF1 gene. (7/78)
Spinal neurofibromatosis (SNF) is considered to be an alternative form of neurofibromatosis, showing multiple spinal tumors and cafe-au-lait macules. Involvement of the neurofibromatosis type 1 (NF1) locus has been demonstrated, by linkage analysis, for three families with SNF. In one of them, a cosegregating frameshift mutation in exon 46 of the NF1 gene was identified. In the present study, we report four individuals from two families who carry NF1 null mutations that would be expected to cause NF1. Three patients have multiple spinal tumors and no cafe-au-lait macules, and the fourth has no clinical signs of NF1. In the first family, a missense mutation (Leu2067Pro) in NF1 exon 33 was found, and, in the second, a splice-site mutation (IVS31-5A-->G) enlarging exon 32 by 4 bp at the 5' end was found. The latter mutation has also been observed in an unrelated patient with classical NF1. Both NF1 mutations cause a reduction in neurofibromin of approximately 50%, with no truncated protein present in the cells. This demonstrates that typical NF1 null mutations can result in a phenotype that is distinct from classical NF1, showing only a small spectrum of the NF1 symptoms, such as multiple spinal tumors, but not completely fitting the current clinical criteria for SNF. We speculate that this phenotype is caused by an unknown modifying gene that compensates for some, but not all, of the effects caused by neurofibromin deficiency. (+info)Optic pathway glioma: correlation of imaging findings with the presence of neurofibromatosis. (8/78)
BACKGROUND AND PURPOSE: Despite the benign histology of optic pathway glioma (OPG) (low-grade astrocytoma), its biological behavior is unpredictable, and it is unclear whether specific morphologic or anatomic patterns may be predictive of prognosis. It is also unclear whether OPG associated with neurofibromatosis (NF) is a distinct entity from non-NF-OPG. Our purpose was to describe the MR imaging features of OPG, compare the findings between patients with and those without NF, and identify prognostic imaging signs. METHODS: MR examinations of 91 patients with OPG (47 with NF and 44 without) were reviewed at presentation and during follow-up. The images were evaluated for size and extension of tumor, and imaging parameters. Statistical bivariate analysis was used to compare the patients with and those without NF, and Pearson correlation was used to evaluate the correlation between the different imaging parameters and prognosis. Kappa values were calculated to determine intraobserver and interobserver variability. RESULTS: The most common site of involvement in the NF group was the orbital nerve (66%), followed by the chiasm (62%). In the non-NF group, the chiasm was the most common site of involvement (91%); the orbital nerves were involved in only 32%. Extension beyond the optic pathway at diagnosis was uncommon in the NF group (2%) but frequent in the non-NF group (68%). In the NF group, the tumor was smaller and the original shape of the optic pathways was preserved (91% vs. 27% in the non-NF group). The presence of cystic components was significantly more common in the non-NF patients (66% vs. 9% in the NF group). During follow-up, half the NF patients remained stable, in contrast to 5% of the non-NF group. No statistical correlation was found between imaging features and biological behavior of the tumor. CONCLUSION: NF-OPG is a separate entity from non-NF-OPG, with different imaging features and prognosis, thereby warranting a specific diagnostic, clinical, and therapeutic approach. (+info)Neurofibromatoses are a group of genetic disorders that primarily affect the nervous system. The term "neurofibromatosis" is often used to refer to two specific conditions: neurofibromatosis type 1 (NF1) and neurofibromatosis type 2 (NF2). These conditions are characterized by the growth of tumors on the nerves, called neurofibromas.
Neurofibromatosis type 1 (NF1): This is the most common form of neurofibromatosis, affecting about 1 in every 3,000 people worldwide. NF1 is caused by mutations in the NF1 gene and is characterized by the development of benign tumors on the nerves called neurofibromas. These tumors can develop anywhere on the body, including the skin, spinal cord, and brain. Other common features of NF1 include:
* Freckles in the underarms and groin area
* Lisch nodules (small, noncancerous growths) on the iris of the eye
* Bone abnormalities, such as scoliosis or bowing of the legs
* Learning disabilities or cognitive impairment
Neurofibromatosis type 2 (NF2): This form of neurofibromatosis is much rarer than NF1, affecting about 1 in every 30,000 people worldwide. NF2 is caused by mutations in the NF2 gene and is characterized by the development of benign tumors on the nerves that transmit sound from the inner ear to the brain (acoustic neuromas). These tumors can cause hearing loss, ringing in the ears, and balance problems. Other common features of NF2 include:
* Multiple schwannomas (tumors that develop on the protective covering of the nerves)
* Meningiomas (tumors that develop in the membranes surrounding the brain and spinal cord)
* Skin tumors called neurofibromas, although these are less common than in NF1
It is important to note that while neurofibromatoses can cause a range of symptoms and complications, most people with these conditions have a normal lifespan. With proper medical care and monitoring, it is possible to manage the symptoms and reduce the risk of complications.
