Modern CT- and MRI-based diagnostics of orbital hemangiomas provides not only the exact location, size, and spread of the lesion but also reveals the characteristic structural features of these tumors, and the use of perfusion techniques visualizes hemodynamics of the tumors. CT-perfusion-based hemodynamic parameters of cavernous hemangiomas typical of this type of hemangiomas may be used in the differential diagnosis with other tumors of this location. The use of contrast enhancement and the Fat Sat technique with a scan thickness of not more than 3 mm is optimal for MRI diagnostics of orbital hemangiomas.

Glomus tumors are the most common tumors of the middle ear, occupying the second position among the temporal bone tumors after vestibulo-cochlear nerve neurilemmoma. The tissue of the jugular glomus is an interlacing of capillaries with the inclusion of epithelioid cells. Cytologically they are benign neoplasms, however, their clinical course can be described as aggressive due to their infiltrating growth and destruction of surrounding bone tissue. Such methods as microsurgical resection, embolization of the vascular stroma of the tumor, various types of radiotherapy and combinations of these methods are used for glomus tumors therapy. In FSAI NSPCN named after N. N. Burdenko most patients are sent to the Department of Radiology and Radiosurgery for stereotactic radiation. This study summarizes and analyzes the results of stereotactic treatment of patients with glomus tumors, both newly diagnosed and those after microsurgical excision with embolization for the entire period of this method application.
