Intracranial Calcifications in Cerebral Paragonimiasis

Abstract

Radiological manifestations of cerebral paragonimiasis with special emphasis on calcified cystic shadows have been presented. Observations are based upon the analysis of our personal materials of eight cases with histopathological verification and upon a review of the cases recorded in the literature. Radiological findings are categorised into three groups. Aggregated calcified cystic shadows are believed to be pathognomonic of cerebral paragonimiasis. Their location in the temporo-occipital region seems to be of diagnostic significance. Repeated failures to fill ventricles in pneumoencephalography indicate the presence of diffuse obliteration of the subarachnoidal space due to arachnoiditis.
