Purpose. To assess the possibilities of functional multispiral computed tomography (fMSCT) in orbital tumors. Materials and methods. The patient M, 55 years old, was admitted to ENT doctor with complaints of difficulty in nasal breathing and nasal discharge. After clinical and in-strumental examination, orbital tumor in the posterior part near the oculomotor muscle and optic nerve was found. To clarify the state of the optic nerve and its involvement in the pro-cess, the patient was referred by an ophthalmologist to an additional orbit examination using functional MSCT. Functional MSCT was performed on a multispiral computer tomograph Toshiba Aq-uilion One 640, with slice thickness 0.5 mm, in the soft-tissue mode. During the study, the patient made eye movements from the central position upwards, then down, to the right, to the left, with a return to the central position. The time of functional eye movement study was 7 seconds. Results. During the functional MSCT the optic nerves were symmetrical: the left and right optic nerves with distinct smooth contours have a smooth course and differentiated to the orbital apexes. The movements of the optic nerves were symmetrical, in full volume. Taking into account the results of FMSCT, the tactics of conducting and surgical treatment of the patient was changed due to the lack of connection between the orbit tumor and optic nerve. The patient underwent surgical treatment and removal of left orbit tumor. Histological examination revealed cavernous hemangioma. Conclusion. Functional MSCT is a new promising method in examining patients with neoplasm of orbit. There is an opportunity to obtain additional diagnostic information on the relationship between orbital bone and soft tissue structures with neoplasms within the pre-operative planning and postoperative control.
