Abstract:
To improve the diagnostic level of CT and MRI in intracranial angioreticuloma. 75 cases of intracranial angioreticuloma were examined by CT, and 19 of them were re examined with MRI. The tumor was located in the cerebellum in 67, frontal lobe in 2, temporal lobe in 1, cerebellum with involvement of medulla, great occipital foramen, vertebral canal, spinal cord and cerebropontial angle in 1, respectively. CT displayed cystic low density accompanied by tumor wall nodules (midcystic tumor) in 35, cystic low density in 18, circular cystic wall in 11, parenchymatous high density in 4, and mixed density in 6. Long T 1 and T 2 signals with tumor wall nodules were displayed in MRI in all of 12 patients. Postoperative pathology: 47 were cystic tumors with tumor wall nodules in the size of 0 1～3 0cm in diameter. The tumor was solitary in 71 cases, and multiple is 3, and the mixed tumor of glioblastoma multiforme and multiple angioreticuloma was located in the temporal lobe in 1 patient, which was rare. The tumor should be diagnosed as angioreticuloma when it was located in the cerebellar hemisphere or vermis without the feature of midcystic tumor or parenchymatous tumor in CT and MRI profiles, with the features of obvious reinforcement or paramagnetic vascular empty in tumor, and a short history.
