Spontaneous hepatic hemorrhage as presentation of metastasized papillary thyroid carcinoma: a case report.

Background: Spontaneous hepatic hemorrhage is a rare condition, most commonly diagnosed in patients with hepatocellular carcinoma or hepatic adenomas, and is seldom caused by metastatic disease. In this case report, we present a patient with spontaneous hepatic hemorrhage due to hepatic metastasis of papillary thyroid carcinoma, an exceptionally rare occurrence.

Case presentation: The patient was a 77-year-old white male with a history of atrial fibrillation treated with apixaban. He presented at a local hospital with abdominal pain and nausea. A CT scan revealed a hepatic lesion in segment 3 with an adjacent hematoma. He was referred to our tertiary center and treated conservatively. Further evaluation revealed an intrathoracic goiter containing a tumorous process diagnosed as a papillary thyroid carcinoma (PTC), and the patient subsequently underwent thyroidectomy. A biopsy of the hepatic lesion confirmed it as a PTC metastasis. Due to worsening abdominal pain and anorexia, the patient underwent subacute hepatic segmental resection. Postoperatively, he developed iodine-refractory disease with disseminated metastasis and passed away 22 months after the initial admission.

Conclusions: To our knowledge, this is the first recorded case of metastasized papillary thyroid carcinoma presenting with spontaneous hepatic hemorrhage-adding to the list of rare causes for this condition.
