Acute spontaneous subdural hematoma caused by skull metastasis of hepatocellular carcinoma: case report

This case report describes the chemoembolization of a small hepatocellular carcinoma employing a lipiodol drug delivery system utilizing a novel arterial pathway. Because the target lesion was precariously located adjacent to the inferior heart border and the diaphragm, it was unsuitable for imaging-guided microwave ablation. To achieve chemoembolization, several intraprocedural adaptations were necessary, given the variant anatomy encountered and difficulty accessing the left gastric artery through a celiac artery approach. The left gastric artery was selected from a superior mesenteric artery approach through the pancreaticoduodenal arcade (Rio Branco’s arcade). This case illustrates the importance of a mastery of the vascular anatomy and variants of hepatic arterial flow.

Abstract Introduction Cerebral metastases are the most common cancer of the central nervous system (CNS). Meningeal infiltration by neoplasms that did not originate in the CNS is a rare fact that is present in 0.02% of the autopsies.Epidemiologically, the radiological presentation mimicking a subdural hematoma is even more uncommon. We report a case of meningeal carcinomatosis by an adenocarcinoma of the prostate mimicking a chronic subdural hematoma. Case Report A 60-year-old male patient was diagnosed with prostate cancer in 2011. He underwent radical resection of the prostate, as well as adjuvant hormonal therapy and chemotherapy.Five years later, the patient presented peripheral facial paralysis that evolved with vomiting and mental confusion. Tomography and magnetic resonance imaging scans confirmed the subdural collection.At surgery, the dura was infiltrated by friable material of difficult hemostasis. The anatomicopathological examination showed atypical epithelial cells. The immunohistochemistry was positive for prostate-specific antigen (PSA) and other key markers, and it was conclusive for meningeal carcinomatosis by a prostate adenocarcinoma. Discussion Meningeal carcinomatosis presents clinically with headache, motor deficits, vomiting, changes in consciousness and seizures.The two most discussed mechanisms of neoplastic infiltration are the hematogenous route and retrograde drainage by the vertebral venous plexus. Conclusion Variable clinical presentations may occur in dural metastases; however, the radiological presentation as subdural hematoma is rare. There are few descriptions of cases like this one in the literature.To support the diagnosis, the previous medical history is as important as the complementary exams and the radiological findings, because the symptoms are common at the neurological emergency. To our knowledge, this is the first report of a prostate neoplasm mimicking chronic subdural hematoma in Brazil.
