Purpose: This study was conducted to report the rare presentation of lumbar osteomyelitis and epidural abscess as a complication of a pilonidal cyst.
Methods: A case report is presented.
Results: We describe the rare case of a male patient with diabetes with a recurring pilonidal cyst who developed a lumbar osteomyelitis and epidural abscess three weeks after pilonidal cyst excision with epidural anesthesia, with a fatal outcome despite emergency treatment.
Conclusions: Life-threatening complications should be kept in mind in high-risk patients with repetitive surgery and neurologic involvement.
