[Primary epiploic appendagitis: a case report].

Primary epiploic appendagitis is a rare, self-limiting inflammatory disease of epiploic appendices of the colon. Although treatment options do not include surgery, it sometimes mimics acute abdominal diseases for which surgery is required for treatment. We present the computed tomography findings of this rare disease in our case report. A 21-year-old male patient admitted to the emergency ward with a three-day history of left lumbar pain. Physical examination revealed low-grade fever and tenderness and defense with left lumbar localization; laboratory findings revealed leukocytosis. Abdominal computed tomography workup showed a mass lesion with fat density in the anterior neighborhood of the descending colon, with a hyperdense rim. Antibiotic treatment was started after radiological assessment as primary epiploic appendagitis. Clinical healing was seen on the ninth day from the onset of symptoms.
