Calcifying pseudoneoplasm of the neuraxis

A Probable Case of Calcifying Pseudoneoplasm of the Neuraxis (CAPNON)

Intradural calcifying pseudoneoplasm of the neuraxis presenting as a cauda equina syndrome

BACKGROUND Calcifying nonneoplastic pseudoneoplasms of the neuraxis (CAPNON) have been reported in 59 cases in literature, however, they rarely involve the spinal cord. Owing to the advances in immunohistochemical markers, their structure and origin are better understood now. CASE REPORT We present the case of a 72-year-old female who had longstanding history of low back pain that exacerbated...

Multiple Calcifying Pseudoneoplasms of the Neuraxis

Calcified pseudoneoplasms of the neuraxis (CAPNON) are a rare diagnostic entity. They have been reported intra-cranially as well as in the spine, and are most commonly found at the skull base. This is a case report of a 38-year-old woman who presented with bilateral CAPNON, diagnosed 8 years apart. While there are approximately 46 reported in the current literature of cerebral and spinal fibro-...

Calcified Pseudoneoplasm of the Neuraxis (CAPNON): A Lesson Learnt from a Rare Entity

We present the case of a 39-year-old female with an exceptional rare entity of the neural axis located in the perisylvian region. We discuss the unique features and the subsequent management of this interesting case.

Three Cases of Calcifying Pseudoneoplasm which Involve the Epidural Space of the Spine

Calcifying psuedoneoplasm of the spine is a rare non-neoplastic lesion of unknown origin. Radiologic and histologic manifestations are very variable and clinical symptoms include isolated pain, myelopathy, and radiculopathy. Surgical resection is the preferred option of treatment. This report describes three cases of calcifying pseudoneoplasm in the spine. The first case is a 77-year-old female...
