Objective To explore the clinical features,treatment methods,and outcomes of patients with cerebellopontine angle(CPA)lipoma.Methods The clinical data of 6 patients with CPA lipoma treated at our hospital from January 2009 to January 2022 were retrospectively analyzed.Results All 6 patients presented with unilateral hearing loss,with vertigo,facial nerve dysfunction,and facial pain in 1 patient,respectively.MRI showed characteristic short T1 and long T2 signals,and CT showed low density in all 6 patients.Four patients underwent surgery,and 2 were observed conservatively.After surgery,all symptoms improved except hearing loss.The patients were followed up for 10～151 months after discharge,without any progression of the disease.Conclusions CPA lipoma is a congenital benign lesion with characteristic imaging findings.If obvious clinical symptoms occur,surgery can be performed,but it is difficult to preserve residual hearing.Reducing intracranial pressure during surgery is sufficient,and it is not advisable to pursue tumor resection to a high degree.
