title: An infected renal cyst.
abstract: A patient with a large renal cyst that became infected, after puncture, is reported. A very high LDH of the aspirate was highly suggestive of infection. CT showed air bubbles, a thick wall with little contrast enhancement, and low density content. CT alone cannot differentiate an infected cyst from an abscess necrotic tumor.
