Intracranial aneurysms commonly present with subarachnoid hemorrhage. Rarely, they may attain a large size and manifest exclusively as intracranial space-taking lesions. We have collected a series of 48 cases of large aneurysms; 47 of them have been previously unpublished. To our knowledge, this is the largest series on this subject.
Cerebral angiography is the best means by which an intracranial aneurysm can be demonstrated and studied in vivo. In 16 cases clinical deterioration paralleled a variable degree of enlargement of the aneurysms. In all patients the aneurysms were irregular and/or bior multilocular. Possible factors causing aneurysmal enlargement are discussed.
Intracranial chondromas are rare lesions. Four new cases are added to the previously recorded 122 cases. These tumors originate from rests of cartilaginous cells at sphenoethmoidal and sphenooccipital synchondroses. Clinically, the major symptom is lower cranial nerve palsy; proptosis and visual impairment can also occur. More than 60% of the lesions are calcified. Bone destruction is common. Angiography shows displacement of vessels but no tumor stain. Pneumoencephalography reveals displacement of basal cisterns and the ventricular system. A radionuclide brain scan may show abnormal uptake in the tumor. Computed tomography should prove useful in evaluating cerebral extension. Unusual features in our case material included the presence of associated aneurysms in one.
A unique case of fatal paradoxical muscle embolism in a patient with a traumatic carotid-cavernous fistula is described. The muscle plug intended to occlude a left-sided fistula passed through the large fistula, bypassed the lungs by way of a patent foramen ovale, and embolized through the right carotid artery to lodge the internal carotid and middle cerebral arteries producing fatal brain infarction.
A case of a symptomatic Rathke's cleft cyst in a 10-year-old boy is described. The importance of the intraoperative differentiation between this rare tumor and a craniopharyngioma is discussed.
