Background: A benign tumor known as an acoustic neuroma can form on the auditory nerves that connect the inner ear to the brain and control balance and hearing. Hearing loss and unbalance could result from the tumor's pressure on the nerve. Case presentation: A 52 years old female patient came to the medicine outpatient department with the chief complaint of headache for 8 days and vertigo while walking for 10 days then she develops a hearing loss in the right ear and later imbalance while walking in the previous month. She had a history of accidental injury to the left eyelid, eyebrow, and left cheek. Firstly, computed tomography (CT) scan has been done and after that magnetic Resonance Imaging (MRI) was advised to the patient. Currently, she is operated on for open decompression craniotomy where excision of the tumor was done under general anesthesia after obtaining physical fitness for surgery. Afterward, she was treated with antibiotics, analgesics, and anti-inflammatory medicines, and post-surgery CT was done. Conclusion: Schwann cells that surround the vestibular nerve, typically in the internal auditory canal, can give rise to benign tumors called acoustic schwannomas. Although the findings on CT and MRI were unusual for acoustic schwannomas, minor acoustic schwannomas might also be found and removed during surgery in addition to the huge cysts.
