An Unusual Presentation of Jejunal Diverticulitis Mimicking Acute Cholecystitis.

Jejunal diverticulosis is a rare entity and jejunal diverticulitis is even rarer. Here we review a patient who presented with right upper quadrant pain and elevated white blood cell count, mimicking acute cholecystitis, as well as thrombocytopenia (21x10^3/mcl). The patient was managed non-operatively with antibiotics and had improvement in symptoms and thrombocytopenia. Our study highlights the importance of maintaining jejunal diverticulitis in the differential for right upper quadrant pain, and its association with severe thrombocytopenia.
