Previous reports of primary aberrant regeneration have indicated that its presence is diagnostic or suggestive of intracavernous meningioma or aneurysm. Three cases of extracavernous processes (presumed oculomotor nerve neurilemmoma, meningioma, and asymmetric mammillary body) associated with primary aberrant regeneration are presented. Magnetic resonance imaging was helpful in identifying two processes not noted on computed tomographic scan. Computed tomography was helpful in further delineating the meningioma. The value of magnetic resonance imaging and computed tomographic scan in the evaluation of primary aberrant regeneration is indicated from these cases.
