“…Pelvic mass malignant lesions should be differentiated from benign inflammatory lesions such as endometriosis [11], hemorrhagic corpus luteum [12], which also show high FDG uptake. In ovarian cancer, FDG-PET/CT has a fair sensitivity to detect recurrence in the setting of a rising CA-125 and negative conventional imaging studies [13].…”

A 32-year-old female who suffered from abdominal pain underwent (18)F-fluorodexoyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for the diagnostic workup of pelvic mass lesions. Cystic mass lesions in the bilateral ovaries showed wall thickening and intense hypermetabolism along the rim. In addition, multifocal intense hypermetabolic lymphadenopathies were seen in the left paraaortic lymph node (LN), aortocaval LN, and both common iliac LNs. We interpreted these findings as bilateral ovarian cancer with retroperitoneal metastatic lymphadenopathies rather than endometriosis with reactive lymphadenopathies. However, histopathological examination confirmed the ovarian mass lesions as tubo-ovarian abscesses. We report a case that even if simultaneous hypermetabolic retroperitoneal LNs are seen, intense hypermetabolic lesions in both ovaries can be in consequence of inflammatory change.

“…Fenchel et al observed elevated FDG uptake in five of 23 endometriomas [10]. Jeffry et al reported a 32-year-old woman with left ovarian endometrioma and FDG uptake in the right paravesical area, assumed to be associated with inflammation rather than a cyst [12]. Recently, Derman et al reported a 47-year-old woman who had a pulmonary endometriosis with intense FDG uptake [9].…”

FDG-PET value in deep endometriosis

et al. 2011

Although laparoscopy continues to be the gold standard in the diagnosis of deep endometriosis, non-invasive imaging methods are important for an adequate staging of the disease, as they may determine the site, size, and severity of the lesions and thus contribute to planning the surgical treatment better. An observational study was carried out between April 2008 and June 2009 during which time nine consecutive patients underwent preoperative PET scan examination for clinical suspicion of deep endometriosis. PET scans provide a functional assessment of cellular activity; but in our study, it did not exhibit consistent results.

“…27,28 In addition, benign ovarian lesions, including endometriosis, 29 hemorrhagic corpus luteal cysts, 30 thecoma, 31 and even normal ovaries, 32 can also show increased FDG uptake, mimicking malignant ovarian lesions. Previous case reports have already demonstrated intense FDG uptake in tubo-ovarian abscess lesions.…”
