Left temporal arachnoid cysts are congenital malformations in the left temporal fossa in which cerebrospinal fluid is encapsulated in the walls of the arachnoid membrane.
Arachnoid cysts are not tumors but benign lesions, and their etiology is not clear. They usually occur in the temporal region, posterior cranial recess, or saddle region, and if the left temporal arachnoid cysts are small and often do not present with headache, vomiting, or neurological dysfunction, further observation and periodic review may be considered.
When the left temporal arachnoid cyst increases in size and compresses the surrounding brain tissue and temporal bone, headache, vomiting, thinning and expansion of the left temporal bone, numbness or weakness of the right side of the limbs, epilepsy, etc., then surgical treatment should be considered. The purpose of surgery is to open the connection between the left temporal arachnoid cyst and the surrounding brain sulcus and cerebral pool, and to release or alleviate the pressure of brain tissue and brain function disorders.
Don’t be nervous if you find a left temporal arachnoid cyst, but go to the neurosurgery department of a regular hospital to decide on further treatment according to the size of the cyst and the presence of corresponding symptoms.
