Adoptive immunotherapy with interleukin-2 (IL-2) and lymphokine-activated killer (LAK) cells has been effective in treating some advanced malignancies in animals and humans. One complication of this treatment is a reversible, oliguric, acute renal failure, which has been ascribed to renal hypoperfusion and resultant prerenal azotemia. We serially studied… (More)
Technetium-99m HIDA cholescintigraphy and ultrasonography are noninvasive, safe, simple procedures that can document the presence, location, and extent of a bile leak. Early detection of posttraumatic or postoperative biliary tract disruption can significantly reduce morbidity and mortality. The possibility of biliary tract disruption should be considered… (More)
Conventional radiographic methods allow physicians to visualize bone structure. However, they do not offer information on the bone mineral density (BMD), which can facilitate early diagnosis and treatment of osteoporosis. Bone densitometry, by contrast, helps to detect bone mineral loss at an early stage because it provides accurate quantitative measurement… (More)
Dual tracer scintigraphy has become the procedure of choice for preoperative localization of parathyroid adenomas. The typical protocol used by most laboratories is to initially perform a Tc-99m sestamibi (MIBI) study with early and delayed (2-3 hours) washout phase images. This is followed by a thyroid-specific Tc-99m pertechnetate study. A potential… (More)
Retroperitoneal hemangioma is a rare but clinically significant condition that can be challenging to diagnose and characterize on anatomical imaging alone. We present a case of an 80-year-old woman with diabetes and hypertension, who was found to have an abdominal mass diagnosed first on CT abdomen and pelvis in March 2011 and demonstrated to be stable on… (More)
Physiologic bowel activity on In-111 octreotide imaging is commonly seen. However, on occasion, normal bowel activity may mimic lesions in the abdomen, which can be very difficult to differentiate, particularly after surgical intervention. We report a case of focal bowel activity simulating a lesion in a patient who had an In-111 octreotide scan… (More)
Radionuclide renal scan findings in a patient with iatrogenic rupture of the ureter are reported. Although the literature contains reports of the radionuclide scan in rupture of the ureter from other causes, this, to our knowledge is the first description of the scan findings in iatrogenic rupture.
