Regrowth and progression of multiple calcifying pseudoneoplasms of the neuraxis: Case report
BACKGROUND: Calcifying pseudoneoplasms of the neuraxis (CAPNONs) are clinically rare, nonneoplastic, noninflammatory-calcified lesions of the central nervous system. Resection of a lesion usually indicates good prognosis without recurrence. However, we experienced a unique case of CAPNON that repeat...

Sumario: | BACKGROUND: Calcifying pseudoneoplasms of the neuraxis (CAPNONs) are clinically rare, nonneoplastic, noninflammatory-calcified lesions of the central nervous system. Resection of a lesion usually indicates good prognosis without recurrence. However, we experienced a unique case of CAPNON that repeatedly recurred after resection. CASE DESCRIPTION: A 52-year-old woman with recurrence of an undiagnosed brain tumor, which was resected 12 years ago, was admitted to our institution. Three calcifying lesions along with perifocal edema were detected in the frontal interhemispheric fissure. We performed the second surgery for total removal of the lesions. The patient was diagnosed with CAPNON on the basis of the clinical features of the lesions and medical examination results. However, 14 months after the second surgery, recurrence occurred, and the patient has been followed up conservatively thereafter. CONCLUSION: CAPNONs may indicate healing process associated with an unidentified agent. Maximum resection, including an unidentified agent, is necessary to prevent recurrence. |
