Superficial cerebral and spinal haemosiderosis caused by secondary tethered cord syndrome after resection of a spinal lymphoma

Superficial haemosiderosis results from chronic subarachnoid
haemorrhage during which haemosiderin is deposited in the
leptomeninges around the brain, spinal cord and cranial nerves. We
describe an exceptional case of superficial haemosiderosis
characterised by two special aspects. (1) The cause was a secondary
tethered cord syndrome due to dural adhesions which had developed 8
years after resection of a thoracic lymphoma and (2) an explorative
neurosurgical procedure with complete untethering caused
normalisation of the cerebrospinal fluid and stopped disease
progression.
