We present a 31-year-old female patient with cryptogenic cirrhosis admitted for rectal bleeding secondary to rectal prolapse. During her hospital course, she was found to have severe multi-endocrine dysfunction as evidenced by persistent hypotension, bradycardia, and intermittent hypothermia with hypothyroidism, adrenal insufficiency, and diabetes insipidus, which were confirmed by laboratory testing. Due to the patient's hypothalamic-pituitary dysfunction along with biopsy-confirmed cirrhosis of unknown etiology, magnetic resonance imaging (MRI) of the brain was ordered. The MRI demonstrated a large, heterogeneously enhancing mass centered in the hypothalamus and infiltrating the pituitary stalk. This case stands out because of its diagnostic trajectory where investigating the cause of endocrine dysfunction revealed a cerebral neoplasm that contributed to the patient's development of cirrhosis. There is an established association between hepatic pathologies and hypothalamic masses with the proposed mechanism being deficiencies of growth hormone (GH), insulin-like growth factor-1 (IGF-1), thyroid stimulating hormone (TSH), and consequently, triiodothyronine (T3). GH deficiency predisposes patients to hepatic steatosis while IGF-1 and T3 deficiencies leave the liver more vulnerable to oxidative damage. As such, cranial imaging and endocrine evaluation should be considered in young patients with cryptogenic cirrhosis.
