MR Imaging of Typical Ovarian Hemangioma: A Case Report.

BACKGROUND: Ovarian hemangioma is an extremely rare tumor with atypical clinical manifestations, often discovered incidentally during autopsy or surgery. Approximately 60 cases have been reported in the past, but no more than 10 cases have been investigated by MRI and ultrasound (US). CASE PRESENTATION: ln this paper, we reported a 51-year-old female patient with Ovarian Hemangioma who had no symptoms of abdominal pain, abnormal vaginal bleeding or discharge, or any other discomfort. Laboratory tests revealed an elevated serum carbohydrate antigen (CA125) of 48.99U/ml (reference range: 0-35U/ml). Multiparametric 3.0T magnetic resonance imaging (MRI) showed a cystic solid mass with a clear boundary and regular shape in the left ovarian area and minimal ascites in the abdominal cavity. The histological examination of the mass confirmed an ovarian hemangioma. CONCLUSION: The MRI findings of ovarian hemangiomas are highly similar to those observed in hepatic hemangiomas, emphasizing the distinctive radiological characteristics specific to this condition in the ovary. This paper presents an overview of the typical MRI findings associated with ovarian hemangioma, which holds great importance for accurate diagnosis and effective treatment.

Ovarian hemangioma: Differential diagnosis of ovarian cancer.

INTRODUCTION AND IMPORTANCE: Ovarian cavernous hemangioma is a rare benign vascular tumor primarily found as either an isolated ovarian mass or as diffuse abdominopelvic hemangiomatosis. Its discovery is often incidental, but symptomatic presentations can occur, including ovarian torsion, can occur without any specification. CASE PRESENTATION: We present the case of a 55-year-old menopausal woman with chronic pelvic pain. Initial diagnostic imaging and tumor markers suggested ovarian malignancy. Subsequent investigations, including ultrasound and MRI, revealed a vascularized adnexal mass with characteristics mimicking malignancy. Surgical exploration through laparoscopy unveiled an 8 cm multicystic solid-cystic lesion with histopathological analysis confirming a 9 cm cavernous hemangioma. CLINICAL DISCUSSION: Histologically, the lesion displayed features consistent with a benign vascular malformation. Literature review indicates variability in presentations and diagnostic challenges in distinguishing these lesions from malignant ovarian tumors. Treatment involved successful cystectomy via laparoscopic surgery, ensuring ovarian preservation so as not to increase the cardiovascular risk due to bilateral annexectomy. CONCLUSION: Ovarian cavernous hemangiomas pose diagnostic challenges due to their rarity and potential mimicry of malignancy. Timely recognition through imaging modalities, especially MRI, and confirmation via histopathological examination remain pivotal. Ovarian-sparing surgical interventions are recommended, particularly for younger patients without suspicious tumor features. Despite their rarity, awareness of these lesions is crucial for accurate diagnosis and appropriate management.
