Spontaneous rupture of spinal dermoid cyst with disseminated lipid droplets in central canal and ventricles.
ABSTRACT Free fat in the ventricular space is a rare but well recognized complication of ruptured tumour of dermal origin. However, only 1 patient of spontaneous rupture of spinal dermoid tumour with disseminated fat in the central canal and ventricles has been described in the literature. The authors report an extremely rare case of ruptured intraspinal dermoid and passage of free fatty droplets via the patent central canal to the intracranial CSF space. The detailed clinical presentation, radiological findings, and review of the literature are presented. Despite being rarely reported, spinal dermoid cyst can rupture spontaneously, and free fat disseminate into the ventricles, and in extremely rare cases, fat can enter into the central canal. It is underlinerd that a prompt detection, with the help of MRI is essential in cases of spinal dermoid tumour cyst, with sudden deterioration in neurological condition, keeping in mind, the possibility of free fat in the central canal.

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.British Journal of Radiology 03/2006; 79(938):167-9.

ABSTRACT: Dermoid cysts represent a rare group of tumors manifesting predominantly in adulthood. Rupture of these tumors is well described with it being symptomatic more commonly intracranially as compared to central canal rupture of intraspinally located dermoid tumor which not only is uncommon, but also frequently asymptomatic. The authors report an unusual case of asymptomatic conus dermoid in a young male diagnosed when investigated for a symptomatic isolated central canal rupture. Fatty contents within the central canal may be a harbinger of an underlying dermoid tumor and a whole spine MRI should be performed in such cases to rule out this bizarre presentation.Journal of Neuro-Oncology 09/2007; 84(1):39-40.
