Kiselev Anatoliy Mikhailovich, Leonov Pavel Sergeevich

A clinical case of progressive growth of the arachnoid cyst of the basal sections of the left middle cranial fossa is given in combination with the growing meningioma of the left frontal lobe and osteoma of the temporal parietal region in the 62-year-old female patient. Leading symptoms of the disease were due to the impact of the cyst on nearby structures and manifested itself in the form of impaired vision, tremors and emotional disturbances. he patient's bone flap with osteoma and meningioma was removed in order to release access through the sylvian gap with the purpose of opening and fenestrating an arachnoid cyst with chiasmatic and carotid cisterns, followed by the plasticity of the skull defect with titanium mesh. Dynamic observation during the year marked a complete regression of the phenomena of compression of the chiasmatic region and disorders in the emotional sphere. In this observation it was demonstrated that the produced fenestration, despite a slight change in the size of the cystic formation, allowed to stabilize the patient's condition for a long time.
