Idiopathic chronic hematocele of the vaginal sac. (1/6)
We report a 39-year-old male who presented non-traumatic testicular swelling and pain. Physical examination and sonography presented a suspicion of testicular tumor and both surgical exploration and inguinal orchiectomy were performed. Hematocele may both clinically and sonographically resemble a testicular tumor. The diagnostic study of choice is magnetic resonance, establishing the diagnosis and differentiating it from neoplasms. (+info)Adenocarcinoma of the rete testis with uncommon presentation as haematocele. (2/6)
Adenocarcinoma of the rete testis was encountered in a 62-year-old man. The tumour was localised in the region of the testicular hilum as a greyish-white nodule that showed no involvement of the adjacent testicular parenchyma or the epididymis. On microscopical examination, there was a well-differentiated adenocarcinoma separated by fibrovascular stroma, entirely confined to the testicular hilum. This primary carcinoma of the rete testis presented as a haematocele. (+info)Scrotal migration of a ventriculoperitoneal shunt: a case report and review of literature. (3/6)
Ventriculoperitoneal (VP) shunt insertion may be associated with migration into the abdominal wall, gastrointestinal tract, bladder, vagina, scrotum, and mediastinum. Migration of the VP shunt into the scrotum has been rarely reported. We present a 1 year old boy with cerebrospinal fluid hydrocele due to the migration of a VP shunt catheter into the right side scrotum. (+info)Hematocele after laparoscopic appendectomy. (4/6)
(+info)Chronic ectopic pregnancy. (5/6)
A chronic ectopic pregnancy is a form of tubal pregnancy in which there is gradual disintegration of the tubal wall with slow and/or repeated episodes of hemorrhaging leading to the formation of a pelvic mass. A review of 22 pathologically proven cases of this entity revealed the pelvic mass to be a hematocele, or a sealed-off inflammatory mass composed of blood clots, organized hematomas, and surrounding adhesions. Sonographically, the abnormality is manifested by an extrauterine, complex mass in the adnexa(e) and cul-de-sac. The mass may obliterate uterine margins and be confused for pelvic inflammatory disease, endometriosis, or uterine leiomyomas. With an increased awareness of this entity and its mildly symptomatic and protracted clinical course, a preoperative diagnosis should be possible. (+info)Platelet-derived growth factor inhibits bone regeneration induced by osteogenin, a bone morphogenetic protein, in rat craniotomy defects. (6/6)
Platelet-derived growth factor (PDGF) is a potent moderator of soft tissue repair through induction of the inflammatory phase of repair and subsequent enhanced collagen deposition. We examined the effect of recombinant BB homodimer PDGF (rPDGF-BB) applied to rat craniotomy defects, treated with and without bovine osteogenin (OG), to see if bone regeneration would be stimulated. Implants containing 0, 20, 60, or 200 micrograms rPDGF-BB, reconstituted with insoluble rat collagenous bone matrix containing 0, 30, or 150 micrograms OG, were placed into 8-mm craniotomies. After 11 d, 21 of the 144 rats presented subcutaneous masses superior to the defect sites. The masses, comprised of serosanguinous fluid encapsulated by fibrous connective tissue, were larger and occurred more frequently in rats treated with 200 micrograms rPDGF-BB, and were absent in rats not treated with rPDGF-BB. The masses underwent resorption within 28 d after surgery. OG (2-256 micrograms) caused a dose-dependent increase in radiopacity and a marked regeneration of calcified tissue in a dose-dependent fashion within defect sites. However, OG-induced bone regeneration was inhibited 17-53% in the presence of rPDGF-BB. These results suggest that rPDGF-BB inhibited OG-induced bone regeneration and stimulated a soft tissue repair wound phenotype and response. (+info)A Hematocele is a medical term that refers to the collection or accumulation of blood in the tunica vaginalis, which is the sac that surrounds and encloses the testicle. This condition usually results from trauma or injury to the scrotum, which can cause bleeding into the tunica vaginalis. A hematocele may also occur as a complication of surgical procedures involving the scrotal area.
The buildup of blood in the tunica vaginalis can create a palpable mass or swelling in the scrotum, which may be painful or painless depending on the severity of the injury and the amount of blood accumulated. In some cases, a hematocele may resolve on its own as the body reabsorbs the blood over time. However, if the bleeding continues or if the collection of blood is large, medical intervention may be necessary to drain the blood and repair any underlying damage.
It's important to note that a hematocele can sometimes be mistaken for other conditions such as an inguinal hernia or a hydrocele (fluid accumulation in the tunica vaginalis), so proper diagnosis by a healthcare professional is essential for appropriate treatment.
