BACKGROUND
Myelolipoma is an uncommon tumor comprising adipose tissue and normal hematopoietic cells and mainly occurs in the adrenal cortex. Mediastinal myelolipoma is very rare; we report a case of posterior mediastinal myelolipoma that required surgical resection.
CASE PRESENTATION
A 56-year-old male was diagnosed with a posterior mediastinal tumor by computed tomography. The tumor was originally noted in 2005, and during follow-up in March 2014, it was found to have increased in size. During consultation at our hospital, on magnetic resonance imaging (MRI), we considered the possibility that the tumor was malignant. Consequently, we resected the tumor by video-assisted thoracic surgery (VATS). The histopathological findings revealed that the tumor had undergone intrathoracic extramedullary hematopoiesis. However, after considering the patient's background and histopathological findings, we diagnosed the tumor as a thoracic extra-adrenal myelolipoma.
CONCLUSIONS
Pathological analysis was instrumental in clarifying the diagnosis. We recommend surgery as a treatment option for posterior mediastinal tumors.
背景
髓脂肪瘤是一种罕见的肿瘤，由脂肪组织和正常造血细胞组成，主要发生于肾上腺皮质。纵隔髓脂肪瘤极为罕见；我们报告一例需要手术切除的后纵隔髓脂肪瘤病例。
病例介绍
一名56岁男性经计算机断层扫描诊断为后纵隔肿瘤。该肿瘤最初于2005年被发现，在2014年3月的随访中，发现其体积增大。在我院会诊期间，通过磁共振成像（MRI），我们考虑该肿瘤为恶性的可能性。因此，我们通过电视辅助胸腔镜手术（VATS）切除了肿瘤。组织病理学检查结果显示该肿瘤发生了胸内髓外造血。然而，综合考虑患者的背景和组织病理学检查结果后，我们将该肿瘤诊断为胸内肾上腺外髓脂肪瘤。
结论
病理分析有助于明确诊断。我们建议将手术作为后纵隔肿瘤的一种治疗选择。
