Abstract

Myoepithelial tumours are a rare form of salivary gland neoplasm, and their occurrence in the central nervous system is exceedingly rare. The authors report the case of an 18-year-old Filipino man presenting with headache and weakness, and on imaging showing an extensive parasagittal tumour at the left posterior parietal area with extracalvarial extension. There was no systemic disease. The patient underwent surgery to excise the tumour, with histopathology showing findings consistent with myoepithelioma. There was no further treatment, given the benign histology of the lesion, but there was recurrence after 8 months. Repeat surgery was done for the patient and he is for adjuvant radiotherapy. This appears to be the 10th reported case of a central nervous myoepithelioma, and the first case in the Philippines of a primary parasagittal myoepithelioma in a paediatric patient. Further information is needed to provide diagnostic and therapeutic recommendations.
