Summary In order to study the computerized tomographic (CT) appearances and clinical characteristics of intracranial tumoural haemorrhage (ITH), we analyzed retrospectively fifty-eight patients with ITH and reviewed the literature. As a result, 91% patients had acute or subacute onset and 26% manifested haemorrhage as their first symptoms. CT scanning indicated that intratumoural bleeding occurred in 23 cases, bleeding into parenchyma 18 cases, subarachnoid space 6 cases, ventricle 3 cases and subdural space 8 cases. Thirty-eight patients had emergency operations and the others had selective operations. Both tumours and haematomas were removed all together in all patients. Fifty-five patients were cured or improved and three died during the perioperative stage in our series. Among the patients with ITH, there were 21 metastatic tumours, 19 gliomas, 10 meningiomas, 6 pituitary adenomas, 1 melanoma and 1 acoustic neurilemoma. The onset of most ITH resembled that of cerebrovascular diseases. The location of ITH and the CT appearances of ITH varied in different cerebral tumours. Radical removal of brain tumours with haemorrhage is an effective treatment for ITH, which can greatly decrease the perioperative mortality rate and improve the prognoses of patients.

dren occur predominantly in males with a lower incidence rate of epilepsy, and are frequently associated with multiple neurofibromatosis. Meningiomas in children have a poorer prognosis than those in adults. Degree of the first tumor resection, tumor location, pathological grade and association with neurofibromatosis are the most important factors influencing the patients’ prognoses.

We have examined the clinical characteristics and treatment of ectopic meningiomas (EMs). Samples from 17 patients with EMs were analyzed, and their clinical characteristics, mechanism, and treatment were studied in combination with the literature. The main clinical manifestations of EMs included increased intracranial pressure, epilepsy, local mass, and local occupying effects, but diagnosis of EMs depended on the pathology. Surgical removal can achieve the double objectives of confirmed diagnosis and treatment of tumors. The clinical characteristics of EMs vary with the sites of tumors.Operation is the treatment of first choice. Prognosis is better than that of typical meningiomas.

Summary In order to study the clinical characteristics of chronic expanding intracerebral hematoma (CEICH), we analyzed retrospectively 21 patients with CEICH and reviewed the literature with regard to clinical manifestations, medical imaging features, surgical findings, pathological examinations, diagnoses, treatments and prognoses, etc. All patients recovered well and did not recur 1-2 months after operation, except one, who died of contralateral intracerebral hemorrhage three months later. Patients were followed-up by computerized tomographic (CT) scanning. MRI was useful for the preoperative diagnosis.

Summary Ten cases of chronic epidural haematoma diagnosed between March 1988 and December 1996 are reported. There were eight males and two females ranging in age from 12-48 years. The interval between head injury and the time of diagnosis ranged from 13 days to 3 months with a mean duration of 28 days. There was no mortality or morbidity in this series. The features of chronic epidural haematoma including patient characteristics, time to diagnosis, incidents, pathophysiology, computerized tomographic (CT) scan findings, operative findings, treatment and prognosis are discussed and reviewed in conjunction with the literature.
