“…Various juxta-uterine masses, including subserosal myomas, adnexal masses, bowel mass, and the differentiation among them is often difficult [17]. Kim et al [18] describe that the demonstration of feeding vessels on imaging studies may be helpful in the differentiation of subserosal myomas from other juxta-uterine pelvic masses.…”

Pedunculated subserous leiomyosarcoma is a quite rare presentation of leiomyosarcoma. As of 2013, only three cases have been reported in the literature. In this case report, we document two new cases of pedunculated subserous leiomyosarcoma from uterine fundus. These two cases illustrate the difficulty of making a correct differential diagnosis between a pedunculated subserous uterine leiomyosarcoma and a malignant ovarian tumor before intervention. A review of the literature confirms that this site remains unusual and making the diagnosis is difficult.

“…They are the most common ovarian tumor found in children and adolescents. 12 These tumors are benign 98% of the time and rarely develop malignancies. 13 Complications of mature cystic teratomas include rupture; malignant degeneration; or the most common complication, torsion.…”

“…The techniques include radiography, CT, MRI, and sonography. Olson et al 12 report that a combination of sonography, radiography, or CT will suggest the correct diagnosis in most cases, whereas MR images will help to correctly diagnose a cystic teratoma without exposure to ionizing radiation. In this case, the ovarian mass was initially identified on radiography as an incidental finding.…”

A calcific pelvic mass in a woman with chronic spinal pain: a case of mature cystic teratoma

Objective: The purpose of this case is to describe findings of a mature cystic teratoma and to further provide differential diagnoses for ovarian pelvic masses and calcifications. Clinical Features: A 27-year-old woman presented to a chiropractic teaching clinic with a chief complaint of chronic multilevel spinal pain. During a full spine radiographic examination, radiopaque densities were incidentally identified in the pelvic bowl visualized through a gonad shield. Follow-up pelvic radiography revealed several radiopacities of uniform density localized in the pelvic bowl. Intervention/Outcomes: Medical (gynecological) consultation led to ultrasonography of the pelvis that revealed a mature cystic teratoma. The patient underwent complete excision of the mass through a laparotomy procedure. The patient continued to receive chiropractic treatment of her original cervical and lumbar spine complaints, further suggesting that the pelvic mass was not a source of her musculoskeletal complaints. Conclusion: This case demonstrates the detection and proper referral of a patient with a calcific mass. The presence of a pelvic mass, suspected of arising from the ovary, requires additional diagnostic imaging and careful clinical correlation.

“…To facilitate local staging of cervical cancer in MRI, several authors have proposed the use of VTs to distend the vaginal vault during imaging [9][10]. However, due to increased resolution of MRI imaging, the use of VTs is no longer recommended [11]. The use of VTs for local staging and follow-up of cervicogenital malignancy has not yet been reported for PET/CT, but in order to analyze a potential benefit of VTs for PET/CT examinations of cervicogenital malignancies, high FDG activities in the VT must be prevented.…”

PURPOSE: The aim of the study was to determine the aetiology of FDG uptake in vaginal tampons (VT), a known artefact in premenopausal women evaluated by PET/CT. METHODS: This Institutional Review Board approved study consisted of retrospective and prospective parts. The retrospective analysis included 685 women examined between January 2008 and December 2009 regarding VT presence. PET/CT images were analysed to determine the localization and the standardized uptake value (SUV) of VTs. We prospectively recruited 24 women (20-48 years old) referred for staging or follow-up in an oncology setting between February and April 2010, who were provided a commercial VT to be used during the entire examination after obtaining written informed consent. After image acquisition, VTs were individually analysed for creatinine concentration and blood traces. Statistical significance was tested with the Mann-Whitney U test. RESULTS: In the retrospective part, 38 of 685 women were found to have a VT of which 17 (45%) were FDG positive. A statistically significant correlation was found between FDG activity and VT position below the pubococcygeal line (PCL) (13 ± 11.2 mm). In the prospective study, 7 of 24 (29%) women had increased FDG activity in their VTs (SUV 18.8 ± 11 g/ml) but were not menstruating. FDG-positive VTs were significantly lower in position (14.6 ± 11.4 mm,below the PCL) than FDG-negative VTs (p = 0.039). The creatinine concentration was significantly increased in all seven positive VTs (931 ± 615 mol/l). CONCLUSION: FDG uptake in VTs is caused by urine contamination, which is likely related to localization below the PCL resulting in contact with urine during voiding. Results:In the retrospective part, 38 of 685 women were found to have a VT of which 17 (45 %) were FDG positive. A statistically significant correlation was found between FDG activity and VT position below the pubo-coccygeal line (PCL) (13 ± 11.2 mm). In the prospective study, 7 out of 24 (29 %) women had increased FDG activity in their VTs (SUV 18.8 ± 11 g/ml) but were not menstruating. FDG positive VTs were significantly lower in position (14.6 ± 11.4 mm, below PCL) than FDG negative VTs (p = 0.039).The creatinine concentration was significantly increased in all 7 positive VTs (931± 615 µmol/l). Conclusion:FDG uptake in VTs is caused by urine contamination, which is likely related to localization below the PCL resulting in a contact with urine during voiding.3
