Skin necrosis: a complication of alcohol infarction of a hypernephroma.

A case of skin infarction after transcatheter ablation of a hypernephroma using alcohol is described. Possible avenues for migration are discussed.

Computed tomography in the diagnosis of extramedullary plasmacytoma.

Extramedullary plasmacytomas involving the retroperitoneum are rare. Review of the literature reveals only one case in which computed tomography (CT) findings were illustrated, and this case involved the pancreas. Described here is unusual case in which pancreatic and renal plasmacytomas occurred in a patient who 18 months previously had presented with a solitary plasmacytoma of bone. The clinically unsuspected renal masses was diagnosed by CT, allowing easy biopsy and radiotherapy planning.

CT findings in obstructed upper moieties of duplex kidneys.

Obstructed upper moiety of a duplex kidney is an uncommon diagnostic problem in adults. This is a report on two cases examined by computed tomography (CT) for suspected abdominal and suprarenal masses, respectively. Although CT is not the primary investigative tool for this condition, the unusual presentations allowed us the opportunity of studying the CT appearance.

Ureteric stone displacement using a new technique.

Transcutaneous displacement of ureteric stones has not been widely employed. The technique described here is one in which four ureteric stones were actively displaced into the bladder using a balloon catheter. Major ureteric surgery was thus avoided. This new technique may be useful as an alternative to Dormia basket extraction of ureteric calculi.
