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.

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.

Vertebral vacuum phenomenon - A radiographic manifestation of metastatic malignancy

Gas lucency within intervertebral disc spaces, the vertebral vacuum phenomenon (VVP) was visible radiographically in 12/42 (28%) women with adenocarcinoma of the breast metastatic to bone. In 7/12 (17%) the VVP occurred adjacent to vertebra involved with metastatic tumor and free of significant degenerative changes. Vertebral collapse occurred in all seven women, but was minimal in some when the VVP was prominent. Metastatic malignancy should be considered along with degenerative disease when the VVP is observed.

Pneumoarthropathy: An Unusual Radiographic Sign of Gram-Negative Septic Arthritis

Gas in the joint and periarticular tissues appeared as an early radiographic manifestation of gram-negative septic arthritis of the hip in a diabetic patient. The features of gram-negative septic arthritis are discussed and the value of an early diagnosis is emphasized.

Bone Infarction in Gout

A retrospective analysis of 28 consecutive cases of gout revealed nine (32%) with radiographic evidence of bone infarction. The radiographic manifestations of bone ischemia and the possible mechanism of infarction in gout are discussed.

Bilateral Spontaneous Urinary Extravasation in Ureteral Obstruction

Spontaneous urinary extravasation caused by ureteral obstruction is infrequently encountered. A case is described in which bilateral extravasation was observed, confined beneath the renal capsule on one side.

Duodeno-duodenal fistula — A manifestation of carcinoma of the colon

Two cases of duodeno-duodenal fistula complicating carcinoma of the right colon, both presenting with upper gastrointestinal hemorrhage, are presented. The close proximity of the ascending colon and hepatic flexure and their draining lymphatics to the duodenum are discussed.

Computed tomography of the left gonadal vein.

Abstract Two patients in whom a dilated left gonadal vein was demonstrated by computed tomography and confirmed by angiography are presented. A dilated left gonadal vein may be a normal variant or it may be secondary to markedly increased renal blood flow. It may also be due to renal vein obstruction.

Non-Visualization of Renal Calices During Excretory Urography as an Indicator of Renal Transplant Rejection

Abstract Non-visualization of renal calices on an excretory urogram with satisfactory concentration in the pelvis, ureter and bladder in a renal transplant patient supports a rejection phenomenon. In all 7 patients with this urographic finding kidney transplant rejection was substantiated by laboratory findings.

The skull in renal osteodystrophy

The skull radiographs of 68 patients undergoing dialysis for chronic renal failure were reviewed for evidence of renal osteodystrophy. Four patients (6%) were positive and the unusually severe changes seen in one patient are described in detail. The changes seen in the skull in renal failure, both before and after treatment, are discussed.
