Heterotropic brain tissue in the oropharynx. Report of a case.
A case of a 7-month-old boy with oropharyngeal heterotropic brain tissue is presented. The lesion, which protruded from the right side of the oropharynx, occupied the oropharyngeal space and pressed the tongue forward and downward. A cranial computed tomograph showed that the mass had some radiolucent areas. Surgical treatment was performed to remove the respiratory and feeding distress. Histologically, the lesions consisted of matured glial cells, ependymal clefts with choroid plexus, and scattered pigmented cells in a part of lining cells of cyst wall.
