Spinal Eumycetoma: A Rare Cause of Lumbar Canal Stenosis and Significance of “Dot in Circle”

Spinal Eumycetoma: A Rare Cause of Lumbar Canal Stenosis and Significance of “Dot in Circle”

Mycetoma is a chronic granulomatous disease that is more common in tropical regions with predominant involvement of foot. Spinal mycetoma presenting as lumbar canal stenosis is extremely rare. We hereby present a case of fungal eumycetoma of vertebral column in a 42-year-old male who presented with...
