Abstract

Calcified pseudoneoplasm of the neural axis (CAPNON) is a very rare, non-neoplastic, calcified pathological entity occurring anywhere in the central nervous system (CNS). Overall, less than 100 cases were reported, of which less than 50% were from the spine. We present a case of a 53-year-old lady with a history of L4–L5 radiculopathy, known case of rheumatoid arthritis, and with no previous history of trauma, tumor or infection. MRI showed calcified intradural mass, extending into the right lateral recess, which was isointense on T1- and T2-weighted sequences. Fenestration on right side along with complete resection of the lesion was done. Mass was found adherent around the dura, extending in to right L5 nerve root foramen, and histopathological examination confirmed the diagnosis of CAPNON. At 6 months follow-up, the patient is pain-free with no radicular symptoms. This entity should be taken in as differential in cases of calcified intraspinal and intracranial lesions. Surgical resection is the treatment of choice.
