Massive edema of the ovary: High resolution MR findings using a phased‐array pelvic coil

Abstract

We report a rare premenarchal case of massive ovarian edema in which high resolution MRI findings more accurately reflected characteristic pathologic changes of this condition compared with CT and ultrasound. A potential role of MR in preoperative diagnosis of massive ovarian edema is suggested.

Adnexal torsion: MR imaging findings of viable ovary

“…However, contrast enhancement was clearly defined in the tumor wall and the walls of the follicles, which were scattered throughout the edematous ovary. This finding is against the reported imaging finding of ovarian torsion and massive ovarian edema [2,4]. An absence of enhancement is an important sign of torsion that indicates an interruption of blood flow [2].…”

“…The MR imaging findings of massive ovarian edema, which is regarded to be a rare variant of torsion resulting from partial intermittent torsion [3], are also sporadically reported [4]. Described imaging findings are mixed solid and cystic mass with heterogeneous enhancement in the solid portion only [5], homogeneous mass of prominent high intensity on T2-weighted images [6], or diffusely enlarged mass embedded with multiple small cystic structures located at its periphery [4]. However, the reported imaging findings are for the lesion that could not be salvaged, although a potential role of MR imaging in preoperative diagnosis of massive ovarian edema is recently suggested [4].…”

“…The MR imaging findings include, e. g., thick edematous pedicle, lack of enhancement, engorged vessels around the tumor, signal intensity of hematoma [2]. The MR imaging findings of massive ovarian edema, which is regarded to be a rare variant of torsion resulting from partial intermittent torsion [3], are also sporadically reported [4]. Described imaging findings are mixed solid and cystic mass with heterogeneous enhancement in the solid portion only [5], homogeneous mass of prominent high intensity on T2-weighted images [6], or diffusely enlarged mass embedded with multiple small cystic structures located at its periphery [4].…”

Several cases of successful conservative surgery of massive ovarian edema have been documented in the pathology literature [7].…”

Precocious puberty secondary to massive ovarian oedema in a 6-month-old girl

“…Two report a heterogeneous low-intensity lesion on T1-weighted images (8,21). The third reports multiple non-enlarged follicular lesions located in the peripheral ovarian regions detected using phase-array pelvic coil MRI (22). The fourth case reports diffuse ovarian enlargement with low intensity in T1-weighted images, with multiple follicles located peripherally in the enlarged ovary (23).…”
