Primary retroperitoneal teratoma is a rare entity in adults. It has a distinctive imaging appearance. We describe a case of a 22-year-old patient who was referred to our hospital with the complaint of abdominal distension. Radiological work-up disclosed a retroperitoneal teratoma. Laparotomy with tumour resection was performed. Pathological examination revealed a benign cystic teratoma. The patient is doing well at follow-up.
Midgut volvulus can also appear much beyond the neonatal age group with a variety of clinical presentations, making the clinical diagnosis in such patients very difficult, if not impossible. Identification of the clockwise whirlpool sign on sonography is an accurate way of diagnosing this condition, which can preclude the need for further investigations and can allow prompt surgical intervention.
Intrapericardial teratomas are rare tumors which usually present in infancy. These tumors may be life-threatening because of the associated large pericardial effusion and cardiac compression. Here we present a case of intrapericardial teratoma which presented with cardiac tamponade in a neonate and was diagnosed using multidetector spiral computed tomography. The imaging features, clinical presentation, and differential diagnosis of this seldom-encountered entity are discussed.
Although pregnancy in a rudimentary uterine horn is rare, the correct diagnosis of this condition on routine sonographic examination is critical, because its natural history usually involves the rupture of the pregnant horn during the second or third trimester, resulting in life-threatening bleeding. We report a case in which the diagnosis of right unicornuate uterus with a left noncommunicating rudimentary horn was made in the first trimester on routine sonographic examination.
