Unique linear and nodular MR enhancement pattern in schistosomiasis of the central nervous system: report of three patients.
OBJECTIVE
The purpose of this paper is to describe the unique MR imaging appearance of schistosomiasis of the central nervous system (CNS).


CONCLUSIONS
Contrast-enhanced T1-weighted MR images in all three patients with CNS schistosomiasis revealed a central linear enhancement surrounded by multiple enhancing punctate nodules, forming an "arborized" appearance. Pathologically, this enhancement pattern correlated with a host granulomatous response to Schistosoma species ova. Although the pattern is not present in all cases of CNS schistosomiasis, when it is observed, a diagnosis of CNS schistosomiasis should be considered.
