A Hussain, A Khorsandi, M Gowan, J Daniel. Thoracic Spinal Cord Herniation- Delayed Diagnosis is a Major Concern.. The Internet Journal of Neurology. 2008 Volume 11 Number 2.
A 54 year-old man presented with 3 years of progressive left foot drop and 4 months of proximal weakness in right leg. Hypoesthesia between left T8 and T10 levels. There was 0/5 strength of left ankle dorsiflexors, invertors and evertors. There was 3/5 strength of left hamstring, iliopsoas and right extensor digitorum brevis. No abdominal reflex but brisk ankle and knee jerks. Babinski’s signs with increased tone in both lower extremities. MRI (Figure: A-F) of thoracic spine showed T5/T6 anterior thoracic spinal cord herniation. It is uncommon and often diagnosed late or misdiagnosed as a presumed posterior intradural arachnoid cyst.1,2 Prompt diagnosis and treatment can prevent severe disability.
