case_images: Preoperative MRI, revealing a hyperintense signal of the cord in the D4-D5 region, with a slight and diffuse thickening (Sagittal T2), cetromedullary (axial T2), showing a modest and diffuse enhancement with Gadolinium

case_images: The magnetic resonance imaging (MRI) documented a moderate and diffuse enlargement of medullary cord, in the D4-D5 region, with a central nonhomogeneous T2 hypersignal as well as heterogeneous enhancement after intravenous injection of gadolinium, with a granular pattern (disruption of the blood-brain barrier) [Figure 1].

case_images: The diagnosis of schistosomiasis was based solely on the demonstration of eggs and adult worm in the granuloma supplied for histopathology review [Figure 4], and later confirmed by positivity in serological tests hemagglutination, with all other work-ups inconclusive (no eggs found on stool or urine or rectal snipes, no eosinophilia in peripheral blood, no augmented VS).
