Conclusions

Spontaneous or acquired encephaloceles constitute a rare but known pathological entity in patients with simple or complex partial seizures. Temporal encephaloceles represent the vast majority of the reported cases, but a parietal anatomical location, as in our patient, may also be observed. A high index of suspicion, especially in patients with previous ear, nose, and throat procedures; trauma; middle ear infections; and episodes of recurrent meningitis, along with high-resolution CT and MR studies, can facilitate detection of the presence of an encephalocele. Thorough preoperative planning and meticulous dissection during resection and reconstruction of the bone defect ensure good functional outcome in the vast majority of these patients.
