A Case of Persistent Hiccups Induced by an Enlarging Hepatic Cyst Underneath the Diaphragm.

Although hiccups are regularly self-limited and rarely life-threatening, prolonged hiccups are bothersome, which can significantly decrease the quality of life. Here, we report a case of persistent hiccups coexisting with an enlarging liver cyst situated just below the diaphragm in a patient with autosomal dominant polycystic kidney disease (ADPKD). No other underlying etiologies related to the symptoms were suspected. The cyst was difficult to drain surgically and the patient continued with symptomatic treatment. Although rare, hepatic cysts should be considered a potential cause of prolonged hiccups in patients with ADPKD. We emphasize the significance of systematically excluding potential etiologies that cause prolonged hiccups and considering appropriate therapeutic interventions.
