On examination the patient was shown to have a right-sided Las\u00e8gue's sign, normal strength, hypalgesia in the right S-1 dermatome, and a slight diminution of the right Achilles tendon reflex. Magnetic resonance imaging revealed a 2-cm intradural enhancing lesion at the level of the L-4 vertebra. Laminectomy of L3\u2013L5 vertebrae was performed, and intradural exploration disclosed a blueberry-appearing tumor that was surrounded by an intense arachnoiditis and attached to the right S-1 nerve root. A cystic collection of cerebrospinal fluid was seen caudal to the tumor. Complete removal required transection of the adherent nerve root fascicles. Histological analyses indicate that the lesion was a lobular capillary hemangioma, which, to the authors' knowledge, appears to be one of the first recorded examples of such a case.<\/jats:p>","DOI":"10.3171\/spi.1999.90.2.0239","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:46:08Z","timestamp":1241711168000},"page":"239-241","source":"Crossref","is-referenced-by-count":12,"title":["Lobular capillary hemangioma of the cauda equina"],"prefix":"10.3171","volume":"90","author":[{"given":"Robert N.
