Abstract
Neuroschistosomiasis is a rare manifestation of Schistosoma infection and can either manifest as cerebritis or with spinal cord involvement. We present a case of low back pain and lower limb weakness, which was initially managed as idiopathic transverse myelitis and later on found to have neuroschistosomiasis. A 23-year-old Sudanese gentleman presented with a one-week history of low back pain, lower limb weakness, and urinary retention. An urgent MRI of the spine with contrast showed features suggestive of transverse myelitis. The patient was treated with intravenous methylprednisolone for five days, which showed significant improvement in his symptoms. One week later, the patient developed the same symptoms again. An urgent MRI spine showed an interval progression of MRI findings. Repeat history taking revealed a history of swimming many times in the river Nile. Serology was sent for Schistosoma and came positive with titer 1:1280. He was treated as neuroschistosomiasis with intravenous steroids for three days, followed by praziquantel for five days along with the steroids, after which he showed significant improvement in his lower limb weakness. Spinal neuroschistosomiasis is one of the very rare complications of Schistosoma infection that should be kept in mind when dealing with unexplained myelopathy with a history of travel or origin from an endemic area. If not treated promptly, it can result in severe irreversible complications.
