Adnexal torsions are one among the causes of acute pelvic pain in females. Commonly occurring adnexal torsions are ovarian either involving the normal ovary with functional cysts or an associated mass. Fallopian tube torsions, torsions involving paraovarian, fimbrial cysts and subserosal fibroids are rare. Here we discuss the multimodality imaging approach for the diagnosis of adnexal torsion, its limitations and mimics.

“…This condition is associated with lymphatic and venous obstruction, and is also attributed to incomplete or partial torsion of the ovary (3). The precise mechanism of the transient bilateral ovarian enlargement with subsequent decreased ascites observed in the present case is unclear; however, obstruction and subsequent resolution of venous and lymphatic drainage could cause this condition if incomplete simultaneous bilateral ovarian torsion had occurred (4), with subsequent detorsion of the ovarian pedicle (5).…”

Ovarian stromal hyperthecosis is characterized by diffuse distribution of luteinized stromal cells accompanied by varying degrees of stromal hyperplasia. We report a case of ovarian stromal hyperthecosis with particular regard to magnetic resonance (MR)-pathologic correlation. At initial MR imaging, the central areas of the bilateral ovarian masses showed hypointensity on T1-weighted images and hyperintensity on T2-weighted images, while the peripheries of the bilateral masses showed isointensity to myometrium on T1-weighted images and heterogeneous signal intensities on T2-weighted images. At 15 days after the initial MR imaging examination, a second MR imaging demonstrated shrinkage of the bilateral ovarian masses. Change in the peripheries to predominantly isointensity to myometrium on the T2-weighted images was also observed. The patient underwent bilateral oophorectomy. Microscopic examination revealed scattered nests of lutein cells on a background of densely proliferated ovarian stroma with minimal collagen production in both ovaries. Edema was occasionally seen in the outer portion but was marked in the central zone of the ovaries, particularly on the left. The final pathologic diagnosis was stromal hyperthecosis. With regard to MR-pathologic correlation, the MR findings in the peripheries of the bilateral masses (isointensity relative to myometrium on both T1- and T2-weighted imaging) showed the characteristics of stromal hyperthecosis.

Objective: The goal of this study was to examine the clinical and ultrasonographic features of females who presented with abdominal discomfort and had ovarian torsion against those who did not. Methods: This was a cohort study that looked back included all female patients who presented to a referral private clinic with pelvic and/or abdominal pain between January 2017 and December 2020. Patients who were clinically diagnosed with torsion but had negative intra-operative findings were excluded. Patients who met the criteria were separated into two groups (ovarian torsion vs. no torsion).Symptoms including the type, location and duration of pain, presence of nausea and vomiting, abdominal tenderness, presence of adnexal masses at digital examination, ultrasound findings, pre-operative diagnosis, final diagnosis, as well as surgical management were recorded. Results: During the research period, a total of 65 female patients came with abdominal discomfort, with 17 (26.2%) having ovarian torsion and 48 (73.8%) not having torsion. 1 (5.9%) of the 17 patients with torsion were in their teenage years, 14 (87.4%) were in their reproductive years, and 2 (11.8%) were 51 years or older. All patients who had torsion presented with nausea and vomiting while none of the patients who did not have torsion had nausea and vomiting (p-value<0.0001). As for pain, 38 (79.2%) had moderate pain in the no torsion group compared to none in those who had torsion since all patients who had torsion had severe pain compared to 10 (20.8%) of those who did not have torsion (p-value<0.0001). Eight patients were pregnant, 5 without torsion and 3 with torsion. The length of discomfort in the torsion group was substantially longer than in the non-torsion group (52.6555.02 days vs. 16.3115.85, p-value0.0001, respectively). Three patients were menopausal, 1 with no torsion and 2 had torsion. Around 58% of the patients without torsion had negative Doppler findings for simple cyst compared to 23.5% of those with torsion. All patients who had torsion underwent surgery and all patients without torsion had regression of pelvic mass. For those who had torsion, 35.3% had their ovary removed, 58.8% had the cyst removed while ovary conserved, and 5.9% had drainage for the cyst. Conclusion: Using a combination of presenting symptoms and ultrasonography, ovarian masses may be identified and ovarian torsion suspected. Torsion must be detected early in order to get conservative therapy and maintain the reproductive capacity of younger girls.
