Torsion of an intraabdominal testicular tumor is a rare event. We report a new case and review the literature.
A review of the literature was carried out in order to identify reported cases of an intraabdominal testicular tumor undergoing torsion of its vascular pedicle. Data on histologic type, common presenting signs and symptoms, radiographic studies, and adjuvant therapy were tabulated.
There are 36 reports of an intraabdominal testicular tumor presenting with torsion. The most common histologic types, in descending order, were seminoma, sarcoma, teratoma, embryonal carcinoma, and choriocarcinoma. Common presenting signs and symptoms included pain and/or tenderness, fever, nausea and/or vomiting, and a palpable mass. Most seminoma patients received adjuvant radiation therapy whereas one patient with choriocarcinoma received adjuvant chemotherapy.
Although a rare event, the diagnosis of torsion of an intraabdominal testicular tumor should be considered in any patient presenting with an acute abdomen and a history of cryptorchidism. The presence of a mass may raise the index of suspicion. Preoperative investigation with computed tomography scanning may aid surgical planning.
腹腔内睾丸肿瘤扭转是一种罕见的情况。我们报告一例新病例并复习相关文献。
对文献进行回顾，以确定已报道的腹腔内睾丸肿瘤发生血管蒂扭转的病例。将组织学类型、常见的临床表现、影像学检查及辅助治疗的数据制成表格。
有36例关于腹腔内睾丸肿瘤伴扭转的报告。最常见的组织学类型，按发生率由高到低依次为精原细胞瘤、肉瘤、畸胎瘤、胚胎癌和绒毛膜癌。常见的临床表现包括疼痛和/或压痛、发热、恶心和/或呕吐以及可触及肿块。大多数精原细胞瘤患者接受辅助放疗，而1例绒毛膜癌患者接受辅助化疗。
尽管腹腔内睾丸肿瘤扭转是罕见情况，但对于任何有急腹症且有隐睾病史的患者，均应考虑该病的诊断。肿块的存在可能会提高怀疑指数。术前进行计算机断层扫描有助于手术规划。
