Neuroradiology of the sphenoidal region

The neuroradiological techniques employed in diagnosing a series of 54 lesions involving the superior orbital fissure and cavernous sinus (sphenoidal region) were reviewed in order to compare the value of sphenoidal tomography, pneumoencephalography, cerebral arteriography and sphenoidal venography. The patients included in the series exhibited clinical syndromes of sphenoidal region cranial nerve deficits. Confirmation of the sphenoidal region disorder was obtained in all cases. Of the four procedures, sphenoidal venography and basal tomography yielded the highest rate of positive studies.
