ABSTRACT
A case of giant aneurysm of the intrapetrous portion of the internal carotid artery, with intracranial and extra-cranial extension in an eight-year-old girl, is reported. Intracranial extension was demonstrated by the presence of a large sac projecting above the petrous shadow in a frontal carotid angiogram, and upward displacement of the middle cerebral artery in the post-ligation angiogram. Extracranial extension was shown clinically as a pulsating mass in the nasopharynx, and also radiologically as a widened medial coronoid space. Erosive destruction of the petrous bone and its neighbourhood produced palsies of the 6th, 7th, 8th, 9th and 10th cranial nerves. There was appreciable recovery in the cranial nerve palsies when the patient was assessed clinically two weeks after ligation of the internal carotid artery.

Three cases of neurofibromatosis are reported showing a wide spectrum of roentgen abnormalities affecting the skull and facial bones. One case had macrocrania and multiple calvarial defects; enlargement of the sella turcica and middle cranial fossa was also present. All the three cases had orbital changes either in the form of enlargement, reduced anteroposterior width or loss of bony outlines with an appearance of emptiness. The other two cases showed predominantly facial involvement with hypoplasia of the mandibular body and ramus, abnormal coronoid process, zygomatic arch, hypoplastic maxilla, cystic mandible with abnormal dentition and absence of the osseous external auditory meatus. Intra-orbital calcification was present in one case. The radiological projections required to evaluate such cases are discussed. The 20 degrees occipito-mental view has been found extremely useful and is recommended.
