Xanthogranulomatous Oophoritis: A Radiologic Masquerader
Xanthogranulomatous oophoritis is a rare, chronic inflammatory condition affecting the ovary, characterized histologically by lipid-laden macrophages (foamy histiocytes), plasma cells, and multinucleated giant cells. It is often confused with ovarian neoplasms due to its imaging appearance and clinical presentation. đ¸ Imaging Findings of Xanthogranulomatous Oophoritis 1. Ultrasound (US) Complex adnexal mass : May appear as a multiloculated, cystic-solid mass. Heterogeneous echotexture : Due to mixed inflammatory and necrotic tissue. Septations or internal debris : Mimics tubo-ovarian abscess or neoplasm. No specific vascular pattern on Doppler â may or may not show peripheral flow. 2. CT Scan Enlarged ovary or tubo-ovarian mass : Complex with solid and cystic components. Low-attenuation areas : Correspond to necrosis or pus. Peripheral enhancement : Suggests inflammation. Fat stranding and inflammatory changes in adjacent tissues (...
