We report on the case of a seven-year old boy who developed an enlarged swelling of the oropharynx. Clinical examination revealed a well demarcated cystic tumour. Histopathologically the diagnosis of an intramuscular haemangioma could be made because of the multitude of vascular spaces filled with erythrocytes lying between bundles of smooth muscles. Such a lesion coming from the posterior wall of the oropharynx is not described in literature. In differential diagnosis the angiosarcoma and the arteriovenous aneurysm must have been involved since there were multiple arteries and veins lying close together in couples. Moreover the adenotomia carried out one and a half year earlier prompted us to think about the possibility of a traumatic arteriovenous fistula.
我们报告了一名7岁男孩的病例，该男孩口咽出现肿大。临床检查发现一个边界清晰的囊性肿瘤。组织病理学检查显示，由于在平滑肌束之间存在大量充满红细胞的血管间隙，故诊断为肌内血管瘤。文献中未描述这种起源于口咽后壁的病变。在鉴别诊断中，必须考虑血管肉瘤和动静脉瘤，因为有多对动脉和静脉紧密相邻。此外，一年半前进行的腺样体切除术使我们考虑到创伤性动静脉瘘的可能性。
