黄文鹏, 肖晓燕, 邱永康, 杨琦, 宋乐乐, 李莉明, 高剑波, 康磊. 胃肌周细胞瘤一例报道并文献复习[J]. 中华消化病与影像杂志(电子版), 2024, 14(01): 93-96.

肌周细胞瘤(myopericytoma,MPC)是临床极少见的血管周细胞源性软组织肿瘤,多为良性,主要发生于肢体远端皮下软组织,发生于深部器官者罕见[1,2,3]。国内有关胃部受累的MPC迄今尚未报道。本文报道一位45岁的男性患者,于2020年1月就诊于郑州大学第一附属医院,其临床症状不典型,表现为进食后哽咽感和轻微腹痛,胃底病灶经内镜黏膜下剥离术切除后被诊断为MPC。因此在评估胃部占位病变时,MPC应被考虑在鉴别诊断中,并且本文回顾了既往有关MPC在深部器官报道的相关文献,以增进临床医师对其认识。

图1 上消化道钡餐造影图像注:造影示胃黏膜增粗紊乱,胃底部黏膜下见充盈缺损。
图2 CT图像注:2A平扫轴位图像示胃底部软组织密度结节,CT值约42 HU;2B、2C动脉期轴位和冠状位图像示病灶边界清楚,直径约为1.0 cm,CT值约83 HU,呈明显强化;2D静脉期轴位图像示病灶静脉期CT值约76 HU,呈持续性强化。
图3 胃内镜黏膜下剥离术图像注:3A内镜下见胃底表面黏膜光滑、大小约1.2 cm×1.2 cm的隆起;3B以圈套器置于隆起基底部黏膜,收紧圈套钢丝,通以高频电流,强度35 W,切下表面黏膜,暴露瘤体;3C术后大体图像。
