[Echographic differential diagnosis in oculo-orbital tumors]

Within the period October 1987-September 1990, the authors submit 130 patients to clinical examination and ultrasonography the latter performed by adapting commercially available ultrasonograph type Bruel and Kjaer 3405 and Shimasonic. Among the investigated individuals, 25 exhibited oculo-orbital tumours of various types. The cases are assessed considering the following for establishing the diagnosis: clinical examination, ultrasonography, fluorescein angiography, radiotracer and morphopathological examinations. Besides the use an adapted device, the authors propose a simple and fast morphopathological method: the fixation in formaldehyde solution as long as 48 hours.
