ABSTRACT
PURPOSE:
The typical manifestations of neurocysticercosis are described widely in the literature. The purpose of this study is to demonstrate the uncommon presentations of different forms of neurocysticercosis in MR imaging.METHOD:
A retrospective analysis of 172 cases of neurocysticercosis in MR studies was carried out over a period of 13 years. One hundred and four males and 68 females with a mean age of 32 ± 3.7 years were studied. The studies were performed on 1.5 T GE MR units and T1 was used before and after gadolinium injection, T2 and gradient-echo (T2*) sequences.RESULTS:
The authors divided the unusual manifestations of neurocysticercosis into intraventricular, subarachnoid, spinal, orbital, intraparenchymatous, and reactivation of previously calcified lesions. The results obtained were intraparenchymatous 95 cases (55.23 percent); intraventricular 27 cases (15.69 percent); subarachnoid 20 cases (11.63 percent); spinal 6 cases (3.49 percent); orbital 1 case (0.58 percent); reactivated lesion 1 case (0.58 percent); association of intraventricular and intraparenchymatous 12 cases (6.98 percent); association of subarachnoid and intraparenchymatous 6 cases (3.49 percent); association of subarachnoid and intraventricular, 4 cases (2.32 percent).CONCLUSION:
MR imaging is a sensitive and specific method in the analysis of different forms of unusual manifestations of neurocysticercosis, which should appear in the differential diagnosis of parenchymal, ventricular, spinal, cisternal, and orbital lesions
