Schistosomiasis of the conus medullaris

Case contributed by Dr Arthur Daire


3 year old boy presented with back pain and leg weakness after a fall. Plain radiographs of the T-L spine showed no evidence of bony trauma.

Patient Data

Age: 3
Gender: Male

There is fusiform expansion of the conus medullaris with mild T2 hyperintensity. This is consistent with an intramedullary mass. No bone or soft tissue oedema. 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.
