Absent Tc-99m ciprofloxacin (infecton) uptake in a renal abscess.

A 40-year-old male diabetic presented with a 1-month history of flank pain, fever, and chills. Examination revealed pyrexia and left flank tenderness. Pus and red cells were seen on urine microscopy and Klebsiella was isolated from the urine.

Prolonged gastric emptying half-time and gastric hypomotility after drug overdose.

A prospective study was undertaken to determine if gastric motility and emptying are altered by the ingestion of overdoses of tricyclic antidepressants, acetaminophen, opioid-acetaminophen mixtures, carbamazepine or phenytoin. Gastric scintigraphy was used to measure gastric emptying half-time and assess gastric motility in 104 patients at initial presentation and again at follow-up (n = 85). Patients were imaged for 5 hours after being given 20 MBq of 99mTc tin colloid to drink.

Tc-99m sestamibi localization of an ectopic mediastinal parathyroid tumor in a patient with primary hyperparathyroidism.

A 50-year-old woman presented with pain and tenderness in the right flank. Urogram and ultrasound demonstrated the presence of an 8-mm calculus in the right kidney. There were persistently elevated serum calcium levels ranging from 10.

A moving Meckel's diverticulum on Tc-99m pertechnetate imaging in a patient with lower gastrointestinal bleeding.

Meckel's diverticulum is one of the most common causes of lower gastrointestinal hemorrhage in the young. We report a case of a 16-year-old youth who presented with a 3-day history of bright red bleeding per rectum. Clinical examination revealed pallor but nothing else of note.

A patient with extensive blue rubber bleb nevi associated with multiple congenital anomalies: an overlap or a new syndrome?

We report a case of a 13 year old boy with non-familial, multiple blue rubber bleb nevi (BRBN). He also had additional dysmorphic anomalies including a low hairline, low set ears, narrow nares, ptosis, hypotelorism, a high arched palate and downward slanting of the outer canthi. Skeletal deformities included a short, slightly webbed neck, kyphosis, cubitus valgus, non-traumatic luxation of the head of the right radius and a short left little and index fingers.
