Intracranial tumours composed of adipose tissue and abnormal blood vessels are rarely recognized. We report two such cases; one showed the radiological and histological appearances of a combined lipoma and an arteriovenous malformation, the other the appearances of a lipoma with a prominent capillary component. Computed tomography did not give any indication of their vascular nature, but surgery was complicated by intra- and postoperative haemorrhage.
Being a rare clinical entity, discal cyst presents indistinguishably from other causes of lower back pain and radiculopathy. It is an extremely rare pathology with unclear pathogenesis, indeterminate natural history with no consensus on the ideal management of the condition. We report a rare case of discal cyst in a patient who presented to our centre with localised low back pain and subsequently left sided radicular pain. With the aid of MRI and with clear surgical indication we proceeded with endoscopic removal of the cyst and intraoperatively confirmed its origin from the adjacent disc. The patient had immediate relief of his symptoms and no postoperative complications. We recommend that endoscopic surgery can be an effective alternative to conventional open surgery for discal cyst of the lumbar spine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
