We report two cases of lumbar spinal dermoid cysts with asymptomatic rupture and migration of free fat droplets into the central canal. No fatty droplets were seen within the lumbar subarachnoid space. The presence of fat droplets within the central canal is unusual because the central canal is rudimentary in adults. We suggest that hydromyelia secondary to tumour and specific tumour morphology might facilitate the selective rupture of dermoids into the central canal. We recommend a follow up of these patients to detect any possible intracranial migration of fat droplets and resultant complications.

ABSTRACT: The authors report a unique case of a dermoid cyst that ruptured into the lumbosacral subarachnoid space following trauma, resulting in dissemination of cyst contents into the ventricles and cerebrospinal subarachnoid spaces. An intraspinous source should be considered when intraventricular fat is identified without a clear intracranial source.

ABSTRACT: Fat droplets in the cerebrospinal fluid (CSF) is a well-known complication of ruptured intracranial dermoid tumours. We report an unusual case of a ruptured spinal dermoid tumour. MR images showed a tethered spinal cord and an intramedullary fat-containing mass. Fat droplets were revealed in the ventricles and the cisternal spaces on brain CT and brain MR. In the English literature, a ruptured spinal dermoid tumour accompanying a tethered spinal cord is extremely rare.
