Quadrigeminal cisternal arachnoid cysts (QACC) represent a rare group of central nervous system lesions. The clinical presentation varies depending on the size of the cyst and the degree of compression. A retrospective review of QACC cases surgically treated at the Instituto Nacional de Salud del Niño San Borja between 2017 and 2024 was conducted. Sociodemographic and clinical data were collected from patient medical records. During the study period, 10 patients diagnosed with QACC underwent surgery. Five presented with type I and five with type III QACC. Neuroendoscopy with cyst fenestration was performed in 80 % of cases. Seventy percent of patients required only one surgery, and 50 % remained free of cerebrospinal fluid shunting. A reduction in cyst size was observed in nine patients, while complete resolution of the lesion occurred in one patient after two surgeries. This case series suggests that neuroendoscopy with cyst fenestration improves the clinical outcomes of QACC and results in cyst size reduction or resolution.
