MR imaging of mediastinal pseudocyst.

Magnetic resonance imaging of a mediastinal pseudocyst clearly demonstrated the entirely intrathoracic location of the pseudocyst.

Sonographic demonstration of bladder-flap hematoma

A bladder‐flap hematoma is generally thought of as a blood collection in a potential space located between the urinary bladder and lower uterine segment (vesicouterine space). These collections can also extend over the bladder and uterus beneath the peritoneal reflection. In this study, ten patients with a bladder‐flap hematoma were evaluated for fever, mass, or dropping hematocrit after surgery. No one sonographic appearance is specific for bladder‐flap hematoma; however, the diagnosis can be made by finding a mass in the extraperitoneal pelvic space in the postoperative patient.

Intrathoracic Gastric Balloon: Radiographic Recognition of Esophageal Perforation

Perforation of the esophagus is an uncommon but life-threatening complication of balloon tamponade for bleeding esophageal varices. We report 2 cases in which the inflated gastric balloon was seen in the chest on radiographs. This finding strongly suggests esophageal perforation, and prompt intervention is required.

Indium-111 leukocyte scanning. False-negative study in a renal abscess

A 33-year-old man had clinical features of a right renal abscess. Results of excretory urography and ultrasonography showed a focal complex mass lesion in the right kidney. An ln-111 leukocyte scan failed to detect the right renal abscess, which later was aspirated under CT guidance and explored surgically. The role of ln-111 leukocyte imaging in the detection of intra-abdominal abscesses, with limitations of the procedure, is discussed.

Pseudocyst following splenectomy: Impact of CT and ultrasound on its diagnosis and management

Three cases of pseudocysts occurring after splenectomy are presented. Sonography and computed tomography were helpful in diagnosing the pseudocysts as well as providing guidance for subsequent drainage. Demonstration of a cystic mass adjacent to the tail of the pancreas following splenectomy suggests the diagnosis of postsplenectomy pseudocyst and has important implications for clinical management.
