Abstract Because of the orbit’s small size, compiex anatomy, and elaborate functions it is considered diagnostic challenge to evaluate a pahent with an obvious or suspected orbital process, and the clinician is often confronted with the decision to image the patient in order to reach the diagnosis.Ultrasonography (IJS) is among th available techniques in clinical practice besides Computerized Topography (CT) and Magnetic Resonance Imaging (MRI) which are used to rovides a high Resolution images of the orbit and visual pathway.Other innovative applications such as three — dimensional reconstructions of CT images and olor-coding of Doppler imaging in orbital ultrasound are becoming more widespread.The selection of imaging modality is guided by the clinical presentation and is affected by oth the clinician knowledge and experience with orbital disease, and also, the familiarity with the vailable Imaging techniques.Despite the difficulties we encountered through out the study either in the form of the limited umber of patients and the high coast of CT and [viRl in the Menoufiya University Hospital group of atients or the paper work needed from the insurance companies to cover the expenses of each vestigative technique in the Craniofacial Institute group of patients. We were able to collect one undred patients with orbhal lesions Patients were qoud as foHow:I- Metaslatic and Secondary Tumors 6 cases II- Lacrirnal Gland Lesions 6 cases Ill- Mesenchymal Lesions 5 cases lv- Other Mesenchymal lesions 2 cases V- Neurogenic Tumors 3 cases VI- Lymphoprolifrative diseases 3 cases VII- Histocytic Tumors 1 case VIII- Inflammatory and infectious lesions A- Inflammatory Lesions 5 cases |
