title: [Chronic subdural hematoma following advanced cancer: report of three cases].
abstract: Three cases of chronic subdural hematoma (CSH) following advanced cancer are reported. Case 1. A 54-year-old male patient was referred to our clinic in a semicomatose state. Bilateral CSH was evacuated through a pair of burr holes, and consciousness was recovered. However, subependymal hemorrhage occurred at the third ventricle 6 days after the operation. Hematological examination revealed thrombocytopenia. He died 12 days after operation because of hemorrhage in the lung. Postmortem examination disclosed metastatic adenocarcinoma of unknown origin to the dura mater, lymph nodes, lung and bone marrow. Case 2. A 50-year-old male patient who was diagnosed as having gastric cancer was referred to our clinic in a state of deep coma. CT scan revealed CSH and putaminal hemorrhage at the left side. Hematological examination revealed disseminated intravascular coagulation (DIC). After the subdural hematoma was evacuated, the putaminal hematoma enlarged and hemorrhagic infarction at the left temporo-occipital lobes occurred. He died 2 days after operation. Autopsy was not carried out, but histological examination revealed poorly differentiated malignant cells in the outer membrane of the subdural hematoma. Case 3. A 53-year-old female patient who had a history of gastric cancer operated on 4 years ago was admitted to our clinic complaining of headache and vomiting. CT scan revealed bilateral subdural hematoma. Following a pair of burr-holes and irrigation of the hematoma, hemorrhage recurred alternatively at the left side on the 6th and at the right side on the 27th day after the operation. Hematological examination revealed DIC, and bone marrow puncture disclosed metastasis of the adenocarcinoma.(ABSTRACT TRUNCATED AT 250 WORDS)
