RESUMO
A 46-year-old man presented with right upper quadrant pain with a clinical suspicion of cholelithiasis and was referred for an abdominal ultrasound (US). On US evaluation, the liver and gallbladder were normal. Incidentally noted a homogeneous, well demarcated, hyperechoic, 5-cm mass in the inferior portion of the spleen. A subsequent Tc-99m labeled RBC scan showed a 5-cm photopenic area in the inferior portion of the spleen on perfusion and early blood pool images. Subsequent filling in on delayed images with slightly increased uptake relative to surrounding splenic tissue was seen on the final images (85 min). Splenic hemangiomas are rare neoplasms, although they still represent the most common primary neoplasm of the spleen. The incidence of splenic hemangiomas ranges from 0.03-14% in autopsy studies.

A 27-year-old man, who had been shoveling gravel in southern Texas for 3 years, had a history of papules and nodules in the left lateral wall of the abdomen. The lesions increased in number and severity with spread to other regions of the body. A punch biopsy of the right arm lesion revealed intracellular, round and cigar shaped budding yeast. The cultures grew Sporotrichum schenkii. Three-phase bone imaging and a Ga-67 scan defined the extent of the disease including involvement of the right tibia, left second metacarpal, and the left wrist joints, the latter two of which were not apparent on clinical examination.

We describe an unusual case of congenital diaphragmatic hernia in a 6-week-old boy who presented with severe respiratory distress due to torsion of the spleen which had passed up into the chest through a Bochdalek hernia and caused a left hemothorax. Scintigraphy with heat-damaged red cells was diagnostic by showing a damaged but functioning spleen above the diaphragm. Surgical repair and return of the spleen to the abdomen resulted in complete recovery.
