Subarachnoid block in a patient with extensive neurofibromatosis at the back

Neurofibromatosis is an autosomal dominant disease characterized by widespread effects on different systems of the body. A 65 year old male who had to undergo surgery on the left thigh had neurofibromatosis type 1 with extensive neurofibromas all over his body, including the entire back. Patient was given spinal anaesthesia, at L3–L4 intervertebral space. Successful subarachnoid block was obtained and the surgery was performed successfully without any untoward complications.
