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. The patient was treated with antibiotics, but the fever persisted and he was sent for an Infecton scan that showed a large cold area in the superolateral aspect of the left kidney. Whole-body imaging failed to reveal any other abnormal site. Computed tomography (CT) demonstrated a space-occupying lesion with an air-fluid level in the upper part of the left kidney. The patient responded to several weeks of antibiotic therapy.
