A standard program is presented by which a maximum number of muscles which are affected by neuromuscular diseases can be examined with a minimum of radiation. Twenty-four patients of different ages, 12 males and 12 females, were examined. Descriptions of different levels of the skeletal muscular system, with measurements of cross-section and density of a number of important marker muscles are presented. Variations of these parameters with age, sex, and cerebral dominance are discussed. It is concluded that CT scans can greatly enhance our insight into the effects of neuromuscular diseases on normal and abnormal skeletal muscles.

Angiography was found to be more reliable for detecting the presence and specific nature of these malformations. Pathological and radiographic differential features between the various forms of cerebral vascular malformations are discussed.

H. du Boulay Lysholm Radiological Department The National Hospital Queen Square London England Summary This study was undertaken to compare the accuracy of measurements of the ventricular system obtained by the CT scanner and pneumoencephalography (PEG). In it the ventricular system was evaluated in each case by measuring the span of the frontal horns, cellae mediae and third ventricle in relation to the diameter of the inner and outer tables of the skull from the PEG films. The indices of Evans, Schiersmann, and Schaltenbrand and Nürnberger were applied to these measurements. The same indices were obtained using the appropriate CT printouts. A very good measure of agreement was obtained with the indices arrived at from both the CT scan printouts and the pneumoencephalograms.

Takebe Department of Neurosurgery Kyoto University Medical School Kyoto Japan Summary The plain skull roentgenography, angiography, air encephalography or positive contrast medium ventriculography and computed tomography (CT) of twelve cases of suprasellar germinoma were reviewed. In over half of the cases, plain skull roentgenography and angiography showed some abnormalities suggesting a suprasellar mass. CT was found to be the most appropriate for routine examination. And air encephalography or positive contrast medium ventriculography offered decisive information.

Vila Neuroradiological and Neurosurgical Pediatric Section ‘La Fe’ Children's Hospital Valencia Spain Summary Two cases of congenital atresia of the foramen of Monro are described, one 8 days old and the other 2 months old. Both are associated with a parieto-occipital paraventricular diverticulum and spontaneous ventriculostomy with the passing of the cerebrospinal fluid to the posterior fossa and the formation of a cyst in the supracerebellar region which compressed and displaced the structures of the posterior fossa.

Berry Thomas Jefferson University Hospital Philadelphia Pennsylvania USA Yonsei University Medical College Seoul Korea Summary Meningiomas originating in the paranasal sinuses are rare. These tumors are thought to arise from embryonal arachnoid nests which were pinched off and left behind during embryonic development. We have described various radiographic findings of two patients with meningioma arising in the paranasal sinuses (frontal sinus origin in a 65-year-old female, and sphenoid sinus origin in a 26-year-old female). The paranasal origin of meningioma was accurately determined on the basis of CT and arteiography. A review of the 11 cases previously reported and our cases indicates that there are no specific clinical or radiographic findings of meningiomas of the paranasal sinuses.

Rice Section of Neurological Surgery, Department of Surgery University of Louisville School of Medicine, Health Sciences Center Louisville Kentucky USA the Department of Radiology University of Louisville School of Medicine, Health Sciences Center Louisville Kentucky USA Summary The superficial recurrent ophthalmic artery arising from the second portion of the ophthalmic artery is rarely visible angiographically. Described herein is a patient, having a recurrent ophthalmic artery which had hypertrophied to a degree sufficient to supply a highly vascularized meningioma of the petrous ridge. Coexistence of marginal tentorial branches, namely the superficial recurrent ophthalmic artery and the meningohypophyseal trunk, is an embryological dilemma. Furthermore, this case demonstrates the capacity of the ophthalmic artery to supply posteriorly situated neoplasms.
