Background: Persistent hiccups lasting more than 48 hours are rare and have numerous possible causes that require further investigation.
Case presentation: We present a man in his seventies who was admitted to hospital after 11 days of hiccups. The hiccups were preceded by abdominal pain that spontaneously receded after a few hours. At admission he had no abdominal pain during examination, but a CT scan later suggested that the cause was a perforated cholecystitis with an intra-abdominal abscess. The abscess was drained percutaneously and treated with antibiotics, and the hiccups stopped.
Interpretation: Persistent hiccups warrant thorough examination, and it is recommended to consider CT scans of the head and truncus, cerebral MRI scan and an upper GI endoscopy. Treating the underlying cause of hiccups is the ultimate target, while symptomatic treatment simultaneously is preferred.
