There is fusiform expansion of the conus medullaris with mild T2 hyperintensity. This is consistent with an intramedullary mass. No bone or soft tissue edema. No extension into the neuroforamen.
Contrast was not given.
Case Discussion
The differential diagnosis included myxopapillary ependymoma and schistosomiasis (which is endemic in our region).
CSF analysis for Schistosoma serology was not available. Thus, laminectomy and biopsy of the conus mass was done. Histology was positive for Schistosoma haematobium.
Patient was treated medically for schistosomiasis and recovered well.
