Case report: chronic acalculous cholecystitis preceded by Coxsackievirus B4 infection.

A 41-year-old female presented with an 8-month history of right upper quadrant pain, exacerbated by ingestion of saturated fats. The patient was positive for antibodies to Coxsackievirus serotype B4, established by an investigation incited by an acute episode of pleurodynia 8 months before the current presentation. Imaging studies including a hepatobiliary iminodiacetic acid scan showed no gallbladder structural or functional abnormalities.
