盆腔脂肪增多症的影像学诊断

目的：提高对盆腔脂肪增多症的影像学诊断水平。方法：回顾性分析了我院5例盆腔脂肪增多症患者的X线、CT和MRI检查结果，并结合本病的临床特点和文献进行了探讨。结果：5例患者均行膀胱造影，见膀胱颈部拉长，膀胱抬高；4例行静脉肾盂造影(IVP)检查，示双侧输尿管双侧肾盂扩张积水；2例患者行钡灌肠检查，可见直肠伸直，远段乙状结肠伸直抬高；3例行CT检查，示膀胱和直肠周围有大量脂肪密度影；3例行MRI检查，见盆腔内有大量短T1、长T2不均质信号，膀胱呈“倒葫芦”状，MRU可见膀胱变形颈部拉长；所有患者均行B超检查，示双肾盂双输尿管积水。结论：盆腔脂肪增多症行X线、CT和MBI检查有其特征性的表现，合理运用影像学检查手段可减少对本病的误诊，认识这些影像学特征有助于提高对本病的诊断。

The imaging diagnosis of pelvic lipomatosis

Objective:To improve the diagnosis of pelvic lipomatosis.Methods:The X ray,CT and MRI manifestations (of 5 cases) were retrospectively analyzed in our study combined with the clinical characteristic of the disease and the literature.Results:The cystography (5 cases) showed the neck of bladder became longer;IVP (4 cases) demonstrated the hydronephrosis and ureterectasis; Barium enema examination (2 cases) showed the rectosigmoid were unbended and elongated;CT (3 cases) demonstrated abundant lower density tissue(-40 to -100 HU) around the bladder in the pelvis;MRI (3 cases) revealed abundant short T 1 and long T 2 tissue in the pelvis and the figure of the bladder looked like a calabash; B-ultrasongraphy (5 cases) showed the ureterectasis and hydronephrosis.Conclusion:The imagine manifestation of the disease has its charateristics and the diagnosis of pelvic lipomatosis depend on the imaging examination.
