Endodermal cysts, also known as enterogenous, neurenteric, foregut, epithelial, bronchogenic, or respiratory cysts, are rare benign lesions lined by columnar epithelium of a presumed endodermal origin. Endodermal cysts are rarely intracranial, but when this occurs, the cysts are frequently located in the posterior fossa with the most common locations being anterior to the brainstem and within the fourth ventricle. However, an endodermal cyst located in the medulla oblongata is extremely rare.
Here, we present a case of a 23-year-old man with an endodermal cyst located in the medulla oblongata. Although rare, clinicians should be aware that this lesion is differentiated from other cystic lesions of the posterior fossa by the absence of a mural nodule.
Total resection of endodermal cysts in the medulla oblongata is recommended, despite their location and adhesion to surrounding structures, due to its frequent recurrence.
内胚层囊肿，也称为肠源性、神经肠源性、前肠、上皮性、支气管源性或呼吸性囊肿，是一种罕见的良性病变，由推测为内胚层起源的柱状上皮衬里。内胚层囊肿很少发生于颅内，但一旦发生，囊肿常位于后颅窝，最常见的位置是脑干前方和第四脑室内。然而，位于延髓的内胚层囊肿极为罕见。
在此，我们报告一例23岁男性，其延髓存在一个内胚层囊肿。尽管罕见，但临床医生应注意，该病变与后颅窝其他囊性病变的区别在于无壁结节。
鉴于延髓内胚层囊肿经常复发，尽管其位置及与周围结构的粘连情况，仍建议对其进行全切除。
