Abstract
Background and Importance
Calcifying pseudoneoplasms of the neuraxis (CAPNON) is an extremely rare tumor, with nearly 150 cases have been reported in the literature. We present a case of CAPNON at foramen magnum (cervicomedullary junction). We also discuss the histological and radiological features of this rare pathology.
Clinical Presentation
A 35-year-old male patient presented to our center complaining of neck pain for the last 6 months and for the last 3 months has had headaches associated with nausea, blurred vision and papilledema. The patient’s magnetic resonance imaging showed the presence of right craniocervical junction intra-dural extramedullary tumor. Neuro examination showed no neurological deficits. He underwent midline suboccipital craniotomy with C1 laminectomy. The mass was completely resected, and histopathology confirmed it to be a CAPNON.
Conclusion
We presented a new case of CAPNON at cervicomedullary junction. The tumor was radically resected, without any complications. Resection of this kind of tumor is curative, and the need for post-operative chemo or radiotherapy is unnecessary, which depends on the outcome of future research and the long-term follow ups.
