Diffuse nodular enhancement form in spinal cord schistosomiasis.

A, Postcontrast sagittal T1-weighted SE MR image (TR/TE 520/20 ms) of case 5, showing multiple small intramedullary enhancing nodules diffusely involving the distal thoracic cord and conus medullaris (arrows).

B, High-power photomicrograph stained with H & E (×250) of the patient, showing multiple granulomas. Schistosoma ova are seen in the midst of the granulomas surrounded by chronic inflammatory cells (arrows). Arrowheads point to the lateral spines, characteristic of S mansoni ova. The surrounding neural tissues are edematous and infiltrated by chronic inflammatory cells.
