The skeletal manifestations of chronic myelogenous leukemia.

Skeletal lesions were radiographically apparent in 6 of 36 (16%) patients with chronic myelogenous leukemia. The spectrum of radiographic changes including diffuse osteoporosis, focal osteolytic and osteoblastic lesions, chloroma, and arthritis, and their clinical behavior is discussed.

Pedicle injury masquerading as renal contusion: a possible urographic pitfall.

Renal vascular pedicle injuries are relatively rare, accounting for 1-5% of renal injuries [1]. Intravenous urography is generally the initial procedure used to assess the severity of renal damage and the need for further evaluation. Non-function of the injured kidney is a characteristic finding of renal pedicle injury on excretory urography [1, 2, 3, 4]. This finding generally necessitates further expeditious evaluation with renal arteriography. Opacification of the pelviureteric system during excretory urography genereally implies that the renal vascular pedicle is intact and a major renal injury does not exist. We report a case of a major renal vascular injury associated with excretion of contrast at urography--findings mimicking the radiographic features of renal contusion.

Nontropical chyluria associated with pelvic lipomatosis.

A patient never exposed to filarial parasites presented with intermittent chyluria and was found to have coincidental pelvic lipomatosis. The pathophysiology of chyluria and pelvic lipomatosis are reviewed and their possible relationship in the present case is discussed.

The "bull's-eye" falciform ligament: a sonographic finding of portal hypertension.

The umbilical vein may dilate as a collateral in portal venous hypertension and become visible within the echodense fat of the falciform ligament. The resulting "bull's-eye" appearance was visible in 5/47 (11%) of patients with cirrhosis secondary to alcohol abuse. It was not visualized in any patients with cholelithiasis who had no evidence of cirrhosis. When demonstrated by ultrasound, this finding should suggest portal venous hypertension.

Gallium-67 scanning and conservative treatment in acute inflammatory lesions of the renal cortex.

Three cases of suspected acute suppurative lesions of the renal cortex treated successfully with antimicrobial agents are presented. In support of other reports it appears that selected cases, particularly when diagnosed early, may be managed conservatively without surgical drainage. In those cases of severe sepsis, large intrarenal or perinephric abscesses, resistant organisms or those that are refractory to treatment, surgical intervention may be unavoidable. Gallium-67 nuclear scanning is a safe, non-invasive method of locating rapidly these areas of inflammation and has proved to be a useful tool in earlier diagnosis.

Carcinosarcoma of the esophagus: report of two cases.

Carcinosarcomas are malignant tumors containing both epidermal and mesodermal components. They are rare in the esophagus, but when present frequently have a characteristic radiographic appearance presenting as a bulky, intraluminal, polypoid filling defect. Although capable of metastatic spread, their usual indolent nature offers a relatively favorable prognosis.
