Typical case: The patient, male, 67 years old, was admitted to the hospital with the chief complaint of “intermittent headache for 2 weeks”. History: The patient had intermittent headache with no obvious cause 2 weeks ago, tolerable, no nausea, no vomiting, no impairment of consciousness, no twitching of the limbs, no limitation of movement. The cranial MRI performed in the hospital showed that the left occipital region was occupied. In order to seek surgical treatment, the patient was admitted to Beijing Electric Power Hospital and was admitted to the neurosurgery department as an outpatient with “left occipital occupancy”. Since admission, the patient was clear, psychiatric, fluent in speech, eating and sleeping, and normal bowel movements. He was physically fit and had no history of smoking or drinking. On examination: bilateral pupils were equal in size and round, light reflex was sensitive, no nystagmus, gross visual acuity was normal, tongue extension was normal, muscle tone of limbs was normal, bilateral knee tendon reflexes were normal, and bilateral Bartholin’s sign was negative. Beijing Electric Power Hospital performed cranial MRI scan + enhancement suggesting: left parieto-occipital sinus meningioma. The meningioma was closely attached to the sagittal sinus, which made the operation more difficult (Note: because of the location of the paranasal sinus, especially when it is closely attached to the sinus wall, the operation may lead to sinus wall rupture and venous sinus hemorrhage, if the sinus wall is not repaired in time, it may lead to large intracranial blood loss, which may cause serious If the sinus wall is not repaired in time, it may lead to massive intracranial blood loss and serious death. The first day of postoperative review of cranial CT showed that there was no obvious bleeding in the operation area and the tumor was excised completely and cleanly. The patient was discharged from the hospital on August 18, 2015, with clear consciousness, good spirit, no visual field obstruction, normal muscle tone of the limbs, and no special discomfort. The patient was discharged from the hospital with clear consciousness, good spirit, normal visual field, normal muscle strength and muscle tone of the limbs, and no special discomfort. As shown in the figure below, the operation was successful and the patient recovered well after the operation and continued follow-up.
