Abstract
Objective: To report the case of a patient with ascites caused by hypothyroidism associated with turmor marker CA-125 elevation. Case details: A 45-year-old female patient, with a history of epilepsy secondary to traumatic brain injury and heavy drinking and alcohol withdrawal for about 3 months, was referred to the hepatology service of the Fundação Santa Casa de Misericórdia do Pará for the etiological elucidation of ascites. During investigation, liver, neoplastic and infectious diseases were ruled out, and TSH >100UI/ml was observed with refractory ascites. After the introduction of hormonal therapy with levothyroxine at higher doses of 75 mcg/day, the patient's clinical picture of ascites resolved. Final considerations: This case is remarkable because ascites caused by hypothyroidism is a rare clinical condition. As this uncommon cause of ascites is a disease that is easy to diagnose and treat, it should be investigated when other more common etiologies do not explain the clinical condition of the patient in question.
