Yahea A Alzahrani

Background: Calcifying pseudoneoplasm of the neuraxis (CAPNON) is a rare slow growing lesion with approximately 114 cases reported around the world. The pathophysiology still uncertain and incomprehensible. It is occurring either within the skull or within the spine. It has a various presentation clinically, and some variation radiologically and in histopathological findings. Case description: we present a case of 14 years old female patient, presented in ER as recurrent seizures case. CT done for her showing left temporal calcified lesion. Admitted with seizures for multiple time, seizures were reoccurred despite medication even with increasing the dose. Further imaging studies was done, and the diagnosis of CAPNON has become more likely. Treated by surgical resection. Conclusion: Calcifying pseudoneoplasm of the neuraxis (CAPNON) is a rare CNS lesion had an increasing in number of reported cases, thus consider it in the deferential diagnosis of calcified lesion of CNS should be taken. Further studies with same or new tools is necessary to know the origin of the lesion since its pathophysiology still incomprehensible. Follow up with the patients after management may be useful in developing a better therapeutic option.
