Summary
Hemorrhage from brain tumors, often the first sign of a neoplasm, is detectable via computed tomography (CT) scans. CT findings and tumor characteristics can help identify these critical intracranial lesions.
Area of Science:
- Neurology
- Radiology
- Oncology
Background:
- Intracranial tumors can present with spontaneous hemorrhage.
- Hemorrhage may be the initial clinical manifestation of an occult brain neoplasm.
Purpose of the Study:
- To describe the computed tomography (CT) findings in patients with intracranial tumors presenting with hemorrhage.
- To correlate CT findings with histopathological diagnoses and identify predisposing factors.
Main Methods:
- Retrospective analysis of 13 patients with intracranial tumors and hemorrhage over a 4-year period.
- Review of computed tomography (CT) scans, including contrast enhancement characteristics.
- Correlation of imaging findings with surgical or autopsy-confirmed histopathological diagnoses.
Main Results:
- Computed tomography (CT) demonstrated characteristic findings: a neoplastic core, peripheral multifocal clots, and surrounding edema.
- Contrast enhancement, when studied, showed peripheral distribution corresponding to hemorrhage.
- Histopathological examination revealed various tumor types, including glioblastoma multiforme, metastatic carcinomas, oligodendroglioma, and hemangiopericytoma.
- High-grade malignancy and abnormal vascularity were identified as potential predisposing factors.
Conclusions:
- Computed tomography (CT) is crucial for diagnosing intracranial tumors presenting with hemorrhage.
- Specific CT features can suggest tumor hemorrhage, aiding in early diagnosis.
- Tumor vascularity and malignancy grade appear to be important in the pathogenesis of hemorrhage.
