“…While MRI whirlpool sign has been described for ovarian torsion in Indian literature, this is probably the first description of MRI whirlpool sign being employed (in the Indian subcontinent) for diagnosis of tubal torsion. 14,15 This case reinforces the fact that in presence of whirlpool sign with normal appearing ovaries, there is a high index of radiological suspicion for tubal torsion which by itself is a rare entity.…”

“…‘Twisted ovarian pedicle’ sign was seen in seven patients. The fallopian tube or vascular channels were seen in helical configuration on MRI (Figures 2, 4, 6, 8-10) [2,4]. Beaking of the margin of an enlarged ovary due to the twisted pedicle was also seen (Figure 1) [7,8].…”

“…The twisted ovarian pedicle is a pathognomonic sign of ovarian torsion [4]. It is formed due to the twisting of the broad ligament containing the thickened fallopian tube and vascular channels [2]. Fallopian tube or broad ligament comprising vascular channels are seen in helical configuration on MRI [2,4].…”

PurposeOvarian torsion is the twisting of the ovary on its vascular pedicle resulting in vascular compromise. Diagnosis of ovarian torsion is challenging in patients who have atypical clinical or ultrasound (US) findings. The objective of our study was to demonstrate the magnetic resonance imaging (MRI) features of ovarian torsion to help radiologists make a conclusive diagnosis when the clinical and US findings are unclear.Material and methodsWe retrospectively reviewed the clinical and MRI features in 10 females with surgically proven ovarian torsion, who had inconclusive clinical, US, or computed tomography findings.ResultsAll patients showed a significantly enlarged ovary with size ranging from 5 to 18 cm. ‘Twisted ovarian pedicle’ sign was seen in seven patients. Eight cases showed areas of haemorrhage within the ovarian stroma. Non-enhancement of ovarian stroma was observed in six patients. Seven patients showed an ipsilateral deviation of the uterus.ConclusionsMRI features of ovarian torsion include ovarian enlargement, twisted ovarian pedicle, ovarian haemorrhage, abnormal ovarian enhancement, and ipsilateral deviation of the uterus. Awareness of these imaging features will enable the radiologist to recognise ovarian torsion and differentiate it reliably from other benign or malignant ovarian lesions.

“…The twisted pedicle can have a "target" or a snail shell appearance (2). The twisted vascular pedicle can also be seen at MR imaging, although the literature on its appearance is sparse (17).…”

History A 6-day-old female neonate presented to the outpatient pediatric surgery clinic for evaluation of a possible prenatal abdominal mass. The neonate was delivered at term via cesarean section due to macrosomia, with a reported birth weight of 11 lb 8.7 oz (5.23 kg). The patient's postnatal course was remarkable for resolving neonatal hyperbilirubinemia. A physical examination was remarkable for a palpable mass in the abdomen. Maternal risk factors included class II obesity, type 2 diabetes, and metabolic syndrome. Prenatal images obtained at an outside institution were not available at this time. Ultrasonography (US) of the abdomen and pelvis was performed 6 days after birth. Follow-up US at 29 days of life revealed no substantial change in the appearance of the findings. This patient remained asymptomatic, and gadolinium-enhanced (Magnevist; Bayer Pharma, Berlin, Germany) magnetic resonance (MR) imaging of the abdomen and pelvis was performed at 84 days of life. The mass was excised surgically at 89 days of life, and the patient had an uncomplicated postoperative course.
