Fibrous pseudotumor is a benign paratesticular tumor that typically presents as a painless mass of the hemiscrotum. Because this tumor can mimic a malignant process, it is usually not diagnosed preoperatively. We describe a case of fibrous pseudotumor of the tunica vaginalis, demonstrating the ultrasound and magnetic resonance image (MRI) appearance with pathologic correlation.
A 5-year-old boy with a right-sided ventriculoperitoneal shunt presented with a 3-month history of progressively enlarging subperiosteal fluid collection in the scalp, which started in the right parietal region and had spread and extended across the midline to occupy both parietal regions. There were no changes in symptoms or signs from those observed 3 months previously. A CT scan confirmed the collection of fluid under the scalp over both parietal regions. The peritoneal catheter was found to be disconnected from the distal end of the functioning valve, which drained cerebrospinal fluid into the subperiosteal space. Distention of the parietal subperiosteal space led to stretching and tearing of the emissary veins. This resulted in the formation of a hydrohematocele. The spread of fluid to the opposite parietal region may be due to a disorganized and loose attachment of the periosteum to the widely separated sagittal suture.
A case of symptomatic and recurrent sinus pericranii in a 14-year-old boy is presented. A blood-filled cyst was diagnosed after head trauma. The sinus pericranii was surgically removed. One year later the patient presented with blurred vision, headaches, and recurrence at a different site in the skull.
The posttraumatic pneumatocele is a rare intrapulmonary lesion following blunt thoracic injury. By means of a well documented case report this rare form of lung contusion is demonstrated and the clinically important differential diagnosis is discussed.

A patient with untreated rupture of the tunica albuginea underwent surgical exploration 6 weeks after acute scrotal trauma. A layer of epithelium had grown across the bulging seminiferous tubules, and no further surgical repair was necessary. This spontaneous repair phenomenon has not previously been reported pictorially in the human testis. The recommended treatment of testicular rupture is surgical exploration and repair.
BACKGROUND: The use of methotrexate (MTX) by systemic administration in the treatment of unruptured ectopic pregnancy has been reported as a safe and effective method. CASES: We report three cases (one hematosalpinx and two pelvic hematocoeles) of complications after the use of MTX in the treatment of unruptured ectopic pregnancies. All three cases came to our observation for pelvic pain, abnormal bleeding and a pelvic mass after an interval of 3-5 months, subsequent to the disappearance of symptoms and normalization of serum human chorionic gonadotropin beta-subunit (beta-hCG) levels. CONCLUSIONS: These findings suggest that: (a) such complications should be considered before selecting the mode of treatment for ectopic pregnancy; and (b) that an early ultrasonographic control should be performed after MTX treatment even when the decline in beta-hCG levels suggests a successful resolution. This would permit an early diagnosis of these late complications.

A 34-year-old woman had a serum hCG level of 4596 mIU/mL on cycle day 48 and an empty uterus with an IUD in situ. Transvaginal sonography showed a 20 mm ring-like thick-walled hyperechogenic structure within the right ovary. The echogenic ring was surrounded by irregular, hypoechogenic structures suggestive of an ovarian pregnancy with periluteal haemorrhage and blood clots. The ruptured cystic ovarian pregnancy and the corpus luteum were removed by laparoscopy. Histopathology showed isolated chorionic villi within haemorrhagic areas in the vicinity of the corpus luteum. Transvaginal sonography is of diagnostic value in differentiating an ovarian pregnancy from a tubal ectopic pregnancy.
65 patients with penetrating or blunt scrotal trauma underwent scrotal ultrasound. High-resolution real-time sonography was able to differentiate testicular from extratesticular lesions in all cases. Lesions of the epididymis were diagnosed in 14 cases. In epididymal haematoma sonography revealed an hyperechoic enlarged epididymis whereas posttraumatic epididymitis was demonstrable as hypoechoic swelling. 14 testicular ruptures and 6 testicular haematomas without disruption of the tunica albuginea were correctly diagnosed. Diagnosis could be confirmed at operation in 12 cases and by clinical and sonographic follow-up in 8 cases. A heterogeneous parenchymal pattern, contour abnormalities, poorly defined margins and obvious fragmentation of the testicle strongly suggest testicular rupture.
According to our examination of 266 patients, ultrasonography of scrotal contents, specifically of the testes, proves to be a highly reliable, non-invasive diagnostic method. The major advantage of this technique is the fact that it enables adequate evaluation of the testes and exclusion of tumours, even when examination by palpation seems difficult or impossible due to extratesticular alterations (e.g. hydrocele, epididymitis). By means of this method also small, non-palpable lesions of the testes may be clearly demonstrated.

Haematocele is an unusual scrotal disorder in children, and is generally associated with direct trauma to the inguinoscrotal region. A 6-year-old boy with acute communicating haematocele who had a history of blunt abdominal trauma one week earlier is presented. Interestingly, no solid organ injury was detected on his previous admission for abdominal trauma, nor there was a history of hydrocele.
