摘要:

A patient with end–stage renal disease and hypercalcemia was referred for a radionuclide bone imaging study. Deposition of Tc–99m hydroxymethylenediphosphonate was apparent in the lungs and myocardium as well as in the skeleton. Renal uptake was also noted, despite anuria. Computed tomography demonstrated nephrocalcinosis but no myocardial calcification. The cause of myocardial uptake of tracer is unknown. Amyloidosis is suggested as a possibility but is not validated in this case.

摘要:

Abdominal scanning with Tc–99m red blood cells performed in a patient with gastrointestinal bleeding demonstrated a localized area of increased activity in the pelvic region that simulated either bleeding in a mass or encapsulated bleeding. Contrast angiography confirmed that the bleeding was due to a right ectopic kidney.

摘要:

A new cholescintigraphic finding, the “hot rim” sign, is reported in a case of acute cholecystitis. Local inflammation in the gallbladder fossa may be the cause of this phenomenon.

摘要:

False aneurysm of the left ventricle is a rare complication of myocardial infarction with a high propensity for late rupture. Timely diagnosis is important and surgical repair is curative in a high percentage of patients. A case in which a false left ventricular aneurysm was recognized by first pass radionuclide angiography and confirmed by contrast ventriculography is reported. Surgery was then performed successfully. The diagnosis of false left ventricular aneurysm using radionuclide angiography, as well as other diagnostic imaging modalities, is discussed.

摘要:

Although the “doughnut” sign in brain scintigraphy is a well known phenomenon, similar findings have recently been reported in bone scintigraphy in osseous and nonosseous lesions. A skeletal doughnut sign in bone scintigraphy caused by giant cell tumor of the proximal fibula is presented with a brief review of literature.

摘要:

In a 40–year–old Hispanic woman with pain and swelling in the left knee with a prosthesis, the combination of Ga–67 citrate and Tc–99m methylene diphosphonate (MDP) scans was used to indicate that there was a septic prosthetic joint. At surgery, the joint was infected and a foreign body was found. Cultures positive for tuberculosis were found also. The presence of an incongruent Ga–67 and Tc–99m (MDP) scan pattern suggests infection of the prosthetic joint, as in the following case.

摘要:

Many disease states, including neoplasia, have been detected by bone scanning. Among the neoplastic processes detected by bone imaging agents are ovarian tumors, both benign and malignant. This report is concerned with the visualization of a benign Brenner tumor during routine Tc–99m MDP bone scanning.
