Abstract

Abstract Rhabdomyosarcoma (RMS) is a malignant soft tissue tumor of skeletal muscle origin. The head and neck, urinary tract, and extremities are the common sites of origin. Embryonal, alveolar, pleomorphic, and spindle/sclerosing are subtypes. It is more common in childhood and rare among adults. The incidence and risk factors for this disease are mainly largely unknown. RMS is sporadic in most instances; however, it is attributed to familial syndromes in some situations—its metastasis to the lungs, bone marrow, and lymph nodes. Breast and ovary involvement is scarce. Diagnostic workup mainly includes contrast-enhanced computed tomography (CECT) and magnetic resonance imaging (MRI). However, 18 F-fluro-deoxyglucose positron emission tomography ( 18 F-FDG-PET/CT) and PET/MRI are increasing contribution to providing functional insights about tumor biology and improving the diagnostic accuracy of the imaging workup. This report presents a case of the neck's embryonal RMS metastasizing simultaneously to the breast and ovary. PET/CT imaging revealed the unusual pattern, further validated by histopathology.

鼻旁窦胚胎性横纹肌肉瘤转移至乳腺及卵巢的PET/ CT-A分析1例并文献复习

横纹肌肉瘤(Rhabdomyosarcoma, RMS)是一种起源于骨骼肌的软组织恶性肿瘤。头颈部、泌尿道和四肢是常见的发病部位。胚胎型、肺泡型、多形型和梭形/硬化型是亚型。它在儿童中更常见，在成人中罕见。这种疾病的发病率和危险因素在很大程度上是未知的。在大多数情况下，RMS是零星的;然而，在某些情况下，它被归因于家族综合征-它转移到肺部，骨髓和淋巴结。很少累及乳房和卵巢。诊断检查主要包括对比增强计算机断层扫描(CECT)和磁共振成像(MRI)。然而，18f -氟脱氧葡萄糖正电子发射断层扫描(18f - fdg -PET/CT)和PET/MRI在提供肿瘤生物学的功能见解和提高成像检查的诊断准确性方面的贡献越来越大。本报告报告了一例颈部胚胎性RMS同时转移到乳房和卵巢。PET/CT成像显示异常模式，组织病理学进一步证实。
