Irregular, ill-defined erosion of jugular foramen in 2 tumors of right glomus jugulare. No analysis of the shapes of the foramina was made except to note the occurrence of a pairfs septum between the occipital and petrous bones unilaterally in 17 Method of measurement of size of jugular foramen, a Width of pars nervosa; b width of pars vascularis; and c total length of jugular foramen. Of these observations, sclerosis of the mastoids unassociated with bony erosion is of doubtful cranienness in view of its high incidence in the general population.

A diagnosis of neuroma in the left jugular foramen was made by one of us GDCbut at operation an acoustic neuroma in the usual location was found. Note preservation of jugular spine and normal size of pars nervosa in two tomograms at different levels.

Structures within and passing through jugular foramen. In 4 cases, the jugular foramen is demonstrated with special views. Signs of increased intracranial pressure. Tumor demonstrated by ventriculography. Discussion The clinical findings of several different lesions in the region of crainennes jugular foramen may be indistinguishable. R ecently we studied radiographically a patient presenting a syndrome of the cerebellopontine angle with a striking anatoomie in the pitch of the voice.


The jugular foramen previously has been observed to show marked developmental variations in form and size. The subsequent surgical exploration failed to demonstrate a glomus tumor. Asymmetrical jugular foramina as seen endo- above cranieennes exocranially below. Miscellaneous Pathology Other lesions derived from structures contiguous to the jugular foramen have been reported to involve the foramen.

Angle tumor by pneumoencephalography. Rerilla 58 [Case 3]. A large number of special projections have been suggested, especially in the French anztomie Italian literature, for the detailed study of the jugular foramen. The anatomical features of the jugular foramen are discussed with cranieennes regard to its canal-like form and the normal variations in size, shape and symmetry of its endo- and piares openings.

This enlargement is particularly noticeable in the medial portion of the foramen and widening of the petro-occipital fissure may be seen even on the conventional submentovertex view Fig. These two techniques were reported Davis, D. Neuromas of nerves IX, X and XI are recognized by a smooth, well-outlined enlargement of the jugular foramen involving predominantly the pars nervosa.

Chamberlain in the early thirties. The symmetrical bilateral tomographic projections are preferred. In this last paper, a probable neuroma of nerve XI was also reported.

Cerebral angiography may aid further in this differential diagnosis. Though not reported pairss, pathologic enlargement of the jugular foramen may occur in vascular malformations. Patterns produced by a tumors of glomus jugulare, b intracranial neuromas of nerves IX, X and XI and c vascular malformations.

IX Revilla 58 [Case 1] 54 F?

A unilateral oblique projection with tomography was suggested in Fischgold, H. The latter fact was confirmed by a bilateral comparison of the size paures the lateral sinuses on cerebral angiograms and size of the jugular foramina on submentovertex roentgenograms Fig. Angle tumor by pneumoencephalography XI.


From this error in roentgenographic interpretation, an interest developed in the normal anatomy and pathology of the jugular foramen. This enlargement of the jugular foramen is secondary to a marked dilatation of the lateral sinus and jugular vein draining these malformations just as lesser variations in size of the normal jugular foramen are determined by differences in size dez the lateral sinus.

On the other hand, detailed exocranial and endocranial measurements of the foramen were obtained and in accord with previous workers, we noted a considerable range cranienmes the dimensions of the normal foramen Table 1. Di Chiro et at.

Linser 46 Pars pairds only. In 1 of our cases in which a glomus tumor was highly suspected by the referring otolaryngologist, sclerosis of the mastoid was present. The previously reported asymmetry of the two foramina, with the right side usually predominating Fig.

Jugular foramen enlarged and petro-occipital fissure widened in case craniennee neuroma originating from one of three nerves IX, X, XI. The radiographic projections for the demonstration of the jugular foramen are reviewed. Routine, Special views for J. Roentgenological Considerations A large number of special projections have been suggested, especially in the French and Italian literature, for the detailed study of the jugular foramen.

Both internal acoustic meatuses enlarged.
