Both internal acoustic meatuses enlarged. In each of these cases, the involved foramen is enlarged with sharply defined, slightly thickened margins and erosion of the jugular spine Fig. Other lesions derived from structures contiguous to the jugular foramen have been reported to involve the foramen.

Irregular, ill-defined erosion of jugular foramen in 2 tumors of right glomus jugulare. Revilla 58 [Case 1]. Routine, Tomography, Special view for J. The radiographic projections for the demonstration of the jugular cranirnnes are reviewed. Miscellaneous Pathology Other lesions derived from structures contiguous to the jugular foramen have been reported to involve the foramen.

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. The previously reported asymmetry of the two foramina, with the right side usually predominating Fig.

Tumors of the glomus jugulare cranienhes irregular enlargement with hazy contours of the anagomie foramen. Structures neighboring jugular foramen. In these cases, the pars vascularis is increased in size with smooth well-outlined margins, while the pars nervosa is of normal shape and dimensions. Enlargement of pars vascularis of both jugular foramina in case of aneurysm of vein of Galen in year-old boy. In the presence of a syndrome of the cerebellopontine angle, the radiographic evidence of normal internal acoustic meatuses and pathologically enlarged and eroded jugular foramen makes the diagnosis of acoustic neuroma unlikely while suggesting one of the lesions that originate in the jugular foramen.

IX Revilla 58 [Case 1] 54 F? Di Chiro et at. Discussion The clinical findings of several different lesions in the region of the jugular foramen may be indistinguishable.

A large number of special projections have been suggested, especially in the French and Italian literature, for the detailed study of the jugular foramen. Angle tumor by pneumoencephalography XI. Rerilla 58 [Case 3]. Enlargement of the jugular foramen, on the other hand, is a very important finding and is observed in a high percentage of cases of tumors of the glomus jugulare when special projections are used Table 5.

Jugular foramen syndrome and allied syndromes. The pattern of enlargement and erosion of the foramen serves to distinguish those lesions related to structures within the jugular foramen—tumors of the glomus jugulare, neuromas of nerves IX, X and XI, dilatations of the jugular vein secondary to vascular malformation Fig. In this last paper, a probable neuroma of nerve XI was also reported.

Structures within and passing through jugular foramen. Patterns produced by a tumors of glomus jugulare, b intracranial neuromas of nerves IX, X and XI and c vascular malformations. These two techniques were reported Davis, D.

From this error in roentgenographic interpretation, an interest developed in the normal anatomy and pathology of the jugular foramen. Routine, Special views for J. The jugular foramen foramen lacerum posterius actually is a canal that courses anteriorly, inferiorly and laterally from an endocranial to an exocranial opening Fig.

The anatomical features of the jugular foramen are discussed with particular regard to its canal-like form and the normal variations in size, shape and symmetry of its endo- and exocranial openings. Internal acoustic meatus eroded. Though neither jugular foramen is visualized optimally by this method, a comparison of both foramina on the same film is made possible.

Complete bridging of jugular foramen. Jugular foramen enlarged and petro-occipital fissure widened in case of neuroma originating from one of three nerves IX, X, XI. The significant clinical and roentgenographic findings in the 19 cases reported in the world literature are summarized in Table 6.

Chamberlain in the early thirties. Tumor demonstrated by ventriculography. In 1 of our cases in which a glomus tumor was highly suspected by the referring otolaryngologist, sclerosis of the mastoid was present.

Tumors of the glomus jugulare produce a characteristic irregular erosion of the margins of the craniennnes with decalcification of the surrounding bone Fig. Asymmetrical jugular foramina as seen endo- above and exocranially below. 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.

Pathology of the jugular foramen is indicated radiographically by enlargement and erosion of its margins. Right lateral sinus and jugular foramen considerably larger than left. These may be classified broadly as oblique unilateral and symmetrical bilateral, both of which may be combined with tomography Table 4. Normal internal acoustic meatuses A and asymmetrical jugular foramina B in patient with left acoustic neuroma. Tumor demonstrated by retrograde venography and sinusography.

The latter fact was confirmed by a bilateral comparison of the size of the lateral sinuses on cerebral angiograms and size of the jugular foramina laires submentovertex roentgenograms Fig.
