Unilateral Proptosis Due to Orbital Malignancy and Synchronous Carcinoma Elsewhere

Unilateral proptosis due to cerebellar stroke.

Congenital Orbital Teratoma with Unilateral Proptosis.

Teratoma is a rare tumor, containing structures originating from all three germinal layers. The most frequent location of teratoma is the gonads. Orbital teratoma is extremely rare. In 1969, Jensen reported that only 40 cases of orbital teratoma existed in the world. We describe a rare case of orbital teratoma in a 15-day girl who presented with marked proptosis of the left eye. The eyeball was...

Primary 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...

Benign orbital neurilemmoma - an uncommon cause of unilateral proptosis.

The occurrence of neurilemmoma in general is not infrequent, but it is a relatively uncommon orbital neoplasm. Proptosis caused by the tumour may be mistaken for Grave's disease. This report presents two female patients, aged 42 years and 30 years, with progressive unilateral proptosis. The former patient was investigated for Grave's disease prior to discovery of an orbital neurilemmoma mimicki...

Unilateral proptosis.

Twenty-seven children with unilateral proptosis were investigated over a period of 8 1/2 years. Seventeen (63%) of them had local or disseminated malignancy, a higher proportion than in earlier reports. The frequency of inflammatory lesions, particularly ethmoiditis progressing to proptosis, appeared to have decreased, probably because of the liberal use of antibiotics for upper respiratory tra...
