Looking for Brain Tissue in All the Wrong Places: A Rare Case of Middle Ear Neuroglial Heterotopia

Neuroglial heterotopia is a rare entity in which brain tissue is present in an ectopic location. We report a case of neuroglial heterotopia in the tympanic cavity. This entity may have an imaging appearance and clinical manifestation similar to those of a variety of benign and malignant lesions of the tympanic cavity. Therefore, it is important for both clinicians and radiologists to consider this diagnosis when encountering a tympanic cavity lesion.
