title: A Rare Presentation of an Enterogenous Cyst as an Intra-Axial Pontine Lesion.
abstract: A 56-year-old man was admitted to our hospital with intermittent right facial numbness for 1 year and instability on walking for 6 months. Magnetic resonance imaging revealed an ovoid and well-demarcated intra-axial pontine lesion. Cyst fenestration and biopsy were carried out, and the diagnosis of enterogenous cyst was made by magnetic resonance imaging and pathologic findings. Preoperative symptoms resolved completely 3 months after surgery and no evidence of recurrence was found during 3 years of follow-up. Although total resection of enterogenous cysts is recommended, cyst fenestration may be useful if the cyst is adherent to vital neurovascular structures.
