PURPOSE AND MATERIAL AND METHODS: MR findings of 9 surgically proven tubo-ovarian abscesses were analyzed in 8 patients. The images were evaluated for signal intensity characteristics and morphologic appearance of the mass, and presence of secondary changes in adjacent pelvic organs and structures.
The signal intensity of the lesions on T1-weighted images was hypointense to the surrounding muscle and myometrium in 5 patients, isointense in 3 and hyperintense in 1. On T2-weighted images the signal intensity was hyperintense (n = 6) or heterogeneous (n = 3). A thin rim (1-3 mm) with hyperintensity on T1-weighted images was noted in the innermost aspect of the masses. Other findings were ill-defined margin, thickened wall, multiple internal septa, shading and gas collection. "Mesh-like" linear strands were noted in the pelvis in all patients, with involvement of adjacent pelvic organs in 7 and lymphadenopathy in 3.
In this limited number of cases MR imaging showed great potential for demonstrating the extent of the disease, characterizing the lesions and making a specific diagnosis.
目的、材料与方法：分析了8例患者中9个经手术证实的输卵管卵巢脓肿的磁共振成像（MR）表现。对图像进行评估，观察肿块的信号强度特征、形态学表现以及盆腔邻近器官和结构的继发性改变。
在T1加权图像上，5例患者病变的信号强度低于周围肌肉和子宫肌层，3例等信号，1例高信号。在T2加权图像上，信号强度为高信号（n = 6）或不均匀信号（n = 3）。在肿块的最内部可见T1加权图像上呈高信号的薄边缘（1 - 3毫米）。其他表现为边界不清、壁增厚、多个内部间隔、阴影和气体聚集。所有患者盆腔内均可见“网状”线性条索，7例累及盆腔邻近器官，3例有淋巴结病。
在这一有限数量的病例中，MR成像在显示疾病范围、明确病变特征及做出明确诊断方面显示出巨大潜力。
