Title: Imaging diagnosis and differential diagnosis of intracranial non-tumor space occupying lesion
Abstract: Objective To investigate the imaging characteristics of intracranial non tumor space occupying lesion. Methods The imaging data of 49 patients, including 20 cases of brain abscess, 19 cases of brain tuberculosis (or meningeal tuberculosis), and 10 cases of brain parasitic infestation, confirmed clinically, were analyzed retrospectively. Results The CT findings of most cases of brain abscess were in circular shape with the same density as or slightly lower density than that of the normal brain tissue on plain CT scan and with obvious annular enhancement on enhanced CT scan. For tuberculosis induced granuloma, the membrane of the local lesion was unclear on plain scan and most lesions showed small ring signs on the contrast enhanced image. Irregularly low density area was found in 5 cases with pulmonary fluke infection. Multiple lesions and some macular calcification and low density area were found in 2 cases with brain cysticercosis. On the contrast enhanced CT scan, the lesion showed signet ring signs. Conclusion General image analysis is quite important in the diagnosis of intracranial non tumor space occupying lesion. In addition, the combination of the clinical data with those of epidemiology, immunological test of cerebrospinal fluid, and other laboratory examination is necessary.
