Dorsal Dermal Sinus with Epidural Abscess-MRI

Extramedullary T1 hypointense and T2 hyperintense lesion at the level of D5-D6 vertebral level measuring 1.8 x 1.1cm with linear tract in the posterior spinal region. There is resultant cord compression and anterolateral displacement of the spinal cord at this level with altered intramedullary cord signal intensity. These findings possibly indicate dorsal dermal sinus and associated epidural abscess.

Dorsal dermal Sinus with Intramedullary Abscess Formation--MRI

Dorsal dermal sinus, a congenital abnormality associated with spinal dysraphism, can serve as a path for spread of infection inside the spinal thecal sac with its sequelae. Intramedullary abscess formation is an uncommon complication and very few have been reported in the English literature. Case by Dr Sangeeta Aneja, MD Associate Professor & Head of Dept.
