Abstract
Solitary juvenile xanthogranuloma (JXG) in the spinal column is extremely rare. Here, we report and characterize the case of xanthogranuloma of the upper cervical spine. A 18-year-old male presented with neck pain for 3 months, along with progressive quadriparesis and sensory loss of 2 months duration with urinary retention. Motor examination revealed spastic quadriparesis with power of 2/5 in all the 4 limbs. Magnetic Resonance Imaging (MRI) spine with contrast showed a dorsally placed intradural extramedullary lesion at the level of C2-C4 vertebral body. The lesion, measuring 2.9x1.7x1.4 cm, was isointense on T1WI, hypointense on T2WI, and enhanced homogenously on contrast. He underwent an emergency C2-C4 laminectomy and complete excision of the lesion. At 3-month follow-up, he was asymptomatic except for mild neck pain. MRI scan of the cervical spine done at follow-up, revealed complete excision of tumor without any residual lesion. Histopathological examination of the mass revealed a polymorphous population of sheets of bloated pale foamy histiocytes (xanthoma cells), numerous admixed mature lymphocytes and several Touton giant cells. The cells were positive for CD68, a histiocytic marker, and negative for CD1a (excludes LCH) and S-100 (excludes RDD).
