Résumé
The clinical features and management of 22 cases with proptosis is highlighted. Proptosis was unilateral in fifteen and bilateral in seven cases. The common etiologic factors were neoplasms, infections and bleeding diatheses. Of the ten cases with neoplasms as many as 7 expired, whereas of nine cases due to infections only one expired and one developed phthisis bulbi. All three patients with proptosis due to bleeds recovered completely without sequelae. Orbital CT scan was done in fourteen and ultrasound in eight cases, while in five cases both investigations were done. As neoplasms are a frequent cause of proptosis in children and there is a high mortality in this group, a thorough systemic examination and hematological profile is essential to arrive at a speedy diagnosis. CT and USG are useful imaging modalities of the orbit, the latter being particularly useful for follow up of the lesion.

Congenital cholesteatomas of the petrous apex are now frequently being approached by otologists. Involvement of the cerebello pontine angle by this lesion produces a myriad of signs and symptoms. Otological as well as neurosurgical literature is reviewed to achieve an overall understanding of the nature and behaviour of this uncommon but interesting lesion.
