CT and MRI in diagnostic of intracranial cavernous hemangioma

Objective: To investigate the CT and MRI in the diagnosis of intracranial cavernous hemangioma. Methods: Twenty cases of intracranial cavernous hemangioma patients, 15 cases underwent CT scan, 14 cases underwent plain scan, plain and contrast enhanced scan in 12 cases. 20 cases underwent MRI examination. Results: The 20 cases detected out 21 lesions, one case have two lesions, and the rest for a solitary; 14 in brain, the diameter is 1.0~5.1 cm, 7 outside brain and the diameter is 0.5~2.2 cm. Round 14, irregular nodular 5, lobulated 2; Clear boundary 19; 2 is not clear; CT detected out eight lesions, the majority of plain lesions showed high-density, Rare cystic degeneration, Lesions without mass effect or mass effect minor. Calcified lesions may occur which was spotted and was at the center of lesions, most of the enhancement are uneven enhancements; MRI detected 21 lesions, T1WI showed slightly low or mixed signal, T2WI showed high signal or mixed signal. Visibility around the lesions have annular enveloping the low signal caused by the bleeding with Hemosiderosis. Conclusion: The MRI is better in intracranial cavernous hemangioma diagnosis. The combination of CT and MRI can be the effective way to diagnose intracranial cavernous hemangioma.
