Microgallbladder: Self-Remitting Acute Cholecystitis-Like Condition Unique to Patients with Cystic Fibrosis.

Microgallbladder is a nonsurgical medical condition characterized by chronic inflammation and atrophy of the gallbladder, which is considered a highly specific imaging finding unique to patients with cystic fibrosis (CF), and has been incidentally reported on abdominal imaging in up to 45% of cases with CF. The impairment of exocrine water efflux in CF leads to the production of hyperviscous biliary secretions, cholestasis, and transient cystic duct obstruction of the microgallbladder causing microcholecystitis-interestingly a self-remitting acute cholecystitis-like condition without surgical intervention. We present a case report of a 22-year-old male patient with history of CF with multiple hospital admissions for unexplained chronic abdominal pain found to be caused by microgallbladder, which was managed conservatively.

Caustic Injury and Stricture of the Esophagus After Long-Term Phenytoin Use.

A 50-year-old man with a history of epilepsy controlled with phenytoin presented for evaluation of dysphagia. History revealed the patient was taking his phenytoin daily without water. Barium esophagram showed severe stricturing of the mid-esophagus. Upper endoscopy revealed diffuse gross mucosal abnormality with a thick stricture and occasional exudate. Biopsies were consistent with a drug-induced injury with lymphocytic infiltration and epithelial cell necrosis.
