Unilateral Proptosis of Unexplained Origin
نویسنده
چکیده
ORBITAL exploration has shown that the commonest causes of unilateral proptosis of unexplained origin are small cavernous haemangiomata and blood cysts in the muscle cone space not extending to the orbital apex (Mortada, 1962a). When orbital exploration reveals no abnormality but is followed by slowly progressive proptosis, repeated skull x rays usually show that the cause is a deep orbital wall bony tumour or mucocele of an accessory nasal sinus (Mortada, 1963). Further study of more cases of unilateral proptosis of unexplained origin has shown that the syndrome can be produced by other causes.

متن کاملUnilateral Proptosis of Unexplained Origin: Report of Nine Cases.
REESE (1951) and other authors hold that, except when an orbital tumour is palpable, no surgery should be attempted unless a deep orbital tumour affects the function of the eye or the optic nerve. Reese recalled no case in which the orbit had been explored with benefit, merely because of an unexplained unilateral proptosis. Among my series of 130 cases of unilateral proptosis, mostly caused by ...
متن کاملPrimary orbital hemangiopericytoma: an unusual cause of unilateral proptosis.
numerous orbital neoplastic and non neoplastic processes. Various mesenchymal tumours of both fibrohistiocytic and vascular origin are well-described causes. Hemangiopericytomas (HPC) are rare vascular tumours which can infrequently involve the orbit and their incidence is estimated to be 0.8% to 3% of primary orbital tumours1,2. We herein report a new case of orbital HPC revealed by unilateral...
متن کاملNodular fasciitis causing unilateral proptosis.
A case report of an unusual case of nodular fasciitis in the orbit presenting with unilateral proptosis is described, and the radiological features are outlined. The histological features are discussed and the benign nature of the lesion stressed. Nodular fasciitis arising in the orbit and presenting as unilateral proptosis has not previously been reported in the literature.
