1/3. Spontaneous rupture of adrenal pheochromocytoma with capsular invasion.A 67-year-old Japanese man developed a sudden onset of severe right-side upper abdominal pain, nausea and vomiting. On hospitalization, physical examination revealed sweating, tachycardia, hypertension and the appearance of peripheral vasoconstriction. An urgent computed tomography scan with contrast demonstrated a large hematoma in the right retroperitoneal space. A phentolamine test and an 131iodine metaiodobenzylguanidine scan suggested pheochromocytoma. An elective right adrenalectomy was successfully performed after pretreatment for sufficient volume replacement with continuous administration of alpha- and beta-adrenergic blocking agents. Pathological diagnosis was an adrenal pheochromocytoma 9.0 x 6.5 cm in diameter with evidence of capsular invasion, which could be associated with a tear in the capsule.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
2/3. Three-dimensional computed tomography illustration of small bowel obstruction transition points in patients receiving oral contrast: report of 3 cases.Computed tomography (CT) is often the first modality ordered in patients with suspected bowel obstruction. Three-dimensional (3D) CT imaging is now seen as a valuable tool for illustrating pathologic findings to clinicians and surgeons. Three cases are reported in which 3D CT volume rendering was used to demonstrate transition points in proximal small bowel obstructions in patients who had received oral contrast.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
3/3. Unrelenting hypotension associated with an acute abdomen in a comatose hemophiliac child: a case report.A comatose 4-year-old hemophiliac presented with an acute abdomen; subsequently he developed unrelenting hypotension. An immediate exploratory laparotomy was required, without time for determining baseline factor viii (AHF) levels. Despite hypotension and hemorrhage, vigorous intraoperative fluid volume replacement and the administration of fresh frozen plasma and AHF concentrates brought a successful conclusion.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
