背景:腹膜后婴儿血管瘤(RIH),一种原发性腹膜后肿瘤,在临床实践中非常罕见。婴儿血管瘤通常表现在皮肤表面。RIH非常罕见,通常很小。在成年人中,这些肿瘤通常表现为没有特定的临床症状或明确诊断的可检测体征。该病例报告详述了一名诊断为RIH的患者。我们建议在全面评估后完全切除肿瘤,其次是术后病理,得到一个决定性的诊断.我们认为,术中管理关键的腹膜后结构和血管对涉及原发性腹膜后肿瘤的所有手术都提出了重大挑战。一名47岁的男性被诊断出患有胆结石,3个月前因无法解释的恶心和呕吐在其他机构接受了手术。手术后2个月的随访影像学显示,左侧肾极下方有腹膜后肿块。在向我们医院介绍时,患者持续出现间歇性恶心和呕吐,没有其他明显的症状或体征。考虑到患者8年的高血压病史,最初怀疑是副神经节瘤。经过详细评估后,我们进行了腹腔镜肿块切除术。然而,术后病理显示为毛细血管血管瘤(旧术语)/婴儿血管瘤。
结论:RIHs是极其罕见的良性肿瘤。应该排除恶性肿瘤的可能性,在经过全面评估后,建议进行手术切除,经病理检查确诊。
BACKGROUND: Retroperitoneal infantile hemangioma (RIH), a type of primary retroperitoneal tumors, are exceptionally rare in clinical practice. Infantile hemangiomas typically manifest on the skin\'s surface. RIHs are exceptionally rare and typically small. In adults, these tumors often manifest without specific clinical symptoms or detectable signs for a definitive diagnosis. This
case report details a patient diagnosed with RIH. We recommend complete excision of the tumor after a comprehensive evaluation, followed by postoperative pathology, to achieve a conclusive diagnosis. We believe that managing critical retroperitoneal structures and vessels intraoperatively presents a significant challenge for all procedures involving primary retroperitoneal tumors. A 47-year-old male was diagnosed with gallstones and underwent surgery 3 months ago at other institution for unexplained nausea and vomiting. Follow-up imaging 2 months after surgery revealed a retroperitoneal mass below the left renal pole. Upon presentation to our hospital, the patient continued to experience intermittent nausea and vomiting, with no other significant symptoms or signs. Considering the patient\'s 8-year history of hypertension, a paraganglioma was initially suspected. We performed the laparoscopic mass resection after a detailed assessment. However, postoperative pathology revealed it a capillary hemangioma (old term)/infantile hemangioma.
CONCLUSIONS: RIHs are exceedingly rare benign tumor. The possibility of malignancy should be ruled out, and surgical resection is recommended following a thorough evaluation, with the diagnosis confirmed through pathological examination.
