RESUMO
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.
RESUMO
BACKGROUND/OBJECTIVE: To report a case of keratinizing squamous metaplasia of the bladder treated with radical cystectomy. DESIGN: Case report and discussion of management options. METHODS: Keratinizing squamous metaplasia of the bladder is a rare entity that can result from chronic irritative stimuli involving the bladder. It is considered a premalignant condition associated with invasive squamous cell carcinoma. A case report is presented describing the diagnosis and management of keratinizing squamous metaplasia of the bladder in a tetraplegic man with a chronic indwelling urinary catheter. RESULTS: Radical cystectomy with an Indiana continent reservoir was performed after cystoscopy with biopsy confirmed keratinizing squamous metaplasia. Final pathology revealed focal erosion and diffuse keratinizing squamous metaplasia of the bladder with prostatic adenocarcinoma as an incidental finding. CONCLUSIONS: Patients with spinal cord injury who use indwelling catheters for bladder management are at higher risk of developing keratinizing squamous metaplasia. Surveillance for early detection of this entity is recommended. Prophylactic cystectomy is sometimes warranted; however, observation and frequent cystoscopic surveillance to identify potential malignant transformation can be an alternative strategy. An interdisciplinary approach is recommended before consideration of bladder resection.
