Surface-coil MR imaging of orbital neoplasms.

Fifteen patients with orbital neoplasms demonstrated by CT were studied with magnetic resonance (MR) using a 13 cm surface coil and a 0.6 T superconducting magnet. The use of a surface coil allowed for a reduction in slice thickness and a significant improvement in spatial resolution resulting in better demonstration and improved characterization of orbital lesions. All neoplasms (15/15) were demonstrated by MR. The lesions were grouped into four main categories on the basis of signal intensities on T1- and T2-weighted images. CT was superior to MR in displaying densely calcified or bony lesions (two of 15 cases). MR was at least equal or superior to CT in demonstrating the other lesions (13 of 15 cases) and had the added advantage of improved tissue characterization in some cases. With the use of surface coils, MR could become the primary imaging technique for evaluation of orbital neoplasms.

Orbital neoplasms in cats: 21 cases (1974-1990).

Squamous cell carcinoma was the most common neoplasm found in a review of case records of 21 cats with histopathologically confirmed orbital neoplasms. Other neoplasms found were lymphosarcoma, undifferentiated carcinoma, malignant melanoma, adenocarcinoma, fibrosarcoma, chondroma, and hemangiosarcoma. Three (14%) neoplasms were primary, 15 (71%) were secondary, invading the orbit from adjacent tissues, and 3 (14%) were a manifestation of multicentric disease. The most common clinical sign was exophthalmia, followed by chronic epiphora, enophthalmia, and strabismus. Mean survival time after diagnosis was 1.9 months. Ten cats were euthanatized at the time of diagnosis because of extensive disease. Mean survival time of the other 11 cats was 4.3 months. Skull radiography was helpful in diagnosing orbital neoplasms in 8 of 11 cats that had invasion of the orbit by adjacent neoplasms.

A multidisciplinary approach to orbital neoplasm.

The patient with orbital and periorbital neoplasia requires careful assessment of the extent and biologic activity as well as histopathologic categorization. Treatment is optimal through a multidisciplinary approach involving the ophthalmic surgeon, plastic surgeon, neurosurgeon, head and neck surgeon, and oral surgeon.

[Therapy of orbital neoplasms in small animals].

The incidence, clinical signs and diagnostic work-up of orbital neoplasms is briefly discussed. The surgical management of such tumors is discussed in detail on the basis of three clinical cases. Long-term functional and cosmetic results are shown. Intraoperative and postoperative complications are discussed.

[Orbital neoplasms in children].

The incidence, diagnosis and clinical picture of the orbital tumors in children are discussed on the basis of 49 personal cases. Discovered was the preponderance of primary non-malignant tumors. The most frequently encountered tumors were angiomas (27 p.c.), dermatomas (19 p.c.) lymphomas (8 p.c.) and among the malignant tumors--rhabdomyosarcoma (6 p.c.).

[Rare primary malignant orbital neoplasms treated surgically in the I Clinic of Otolaryngology of the Silesian Medical Academy in Katowice in the years 1992-1995].

14 patients suffering from primary orbital tumours were treated surgically in the Otolaryngological Department in Silesian Medical Academy in Katowice in the years 1992-1995. The patients were aged from 23 (woman with neurosarcoma) to 67 (woman with haemangioma). All patients were treated surgically: 8 of them by lateral orbitotomy m. Krönlein-Reese-Berk, 3 of them by orbital exenteration, and 3 of them by canthotomy. The author analysed 3 very rare cases of primary orbital malignant neoplasms: neurosarcoma, rhabdomyosarcoma and additionally I case with fibrosarcoma, osteosarcoma and chondrosarcoma simultaneously.
