Primary Spinal Glioblastoma Mimicking Neuroschistosomiasis: A Case Report

Primary glioblastoma of the spinal cord (sGB) is a rare and challenging diagnosis. In the diagnostic algorithm, reversible causes should be considered while the diagnosis of sGB is under evaluation. We present a case of cervical sGB mimicking neuroschistosomiasis. A 21-year-old Somali man presented with neck pain, sensory disturbances, and spastic tetraplegia. Cervical spine magnetic resonance imaging with contrast showed a heterogeneously enhancing intramedullary mass spanning from the level of the C1 to T3 vertebrae. Cerebrospinal fluid analysis showed a lymphocytic predominance and elevated protein. Due to the patient's history of poorly treated schistosomiasis, praziquantel and dexamethasone were initiated while the diagnostic work-up was completed. Three days after the patient was discharged to a rehabilitation facility where he experienced worsened motor function with radiographic progression of the lesion and increased cord edema. The patient underwent a surgical biopsy which confirmed a diagnosis of primary sGB. sGB is an unusual diagnosis that can masquerade as a non-neoplastic lesion. However, the diagnosis of sGB should be considered in patients with an intramedullary spinal cord lesion who exhibit rapid radiographic and clinical progression.
