Extremely Rare CT and MRI Findings of Peritoneal Leiomyoma Mimicking Hepatic Mass: A Case Report

Abstract

Leiomyoma is a common benign tumor from smooth muscle cells, mostly in the uterus. Peritoneal leiomyomas (PLs) are extremely rare and mostly reported as disseminated peritoneal leiomyomatosis. However, to the best of out knowledge, radiologic findings of isolated PL are not reported in English literature. Herein, we introduce the radiologic findings of PL mimicking hepatic mass in a 34-year-old female. CT showed a mass with curvilinear heterogeneous enhancement at the liver’s peripheral area. On MRI, the mass showed gradual and heterogeneous enhancement on gadoxetic acid-enhanced MRI and diffusion restriction. The radiologic diagnosis was a benign hepatic tumor, such as degenerated hemangioma, adenoma, and inflammatory myofibroblastic tumor; however, the mass was diagnosed as PL pathologically.

Early diagnosis and appropriate management of vaginal leiomyoma in rural areas

“…When there is a solid mass positioned in half of the vagina, an examination is necessary to determine between vaginal leiomyoma, vaginal cyst, or uterine prolapse. [11][12][13] Several diagnostic procedures such as transabdominal ultrasound (US), transvaginal US, translabial US, and MRI can be used to distinguish between vaginal leiomyoma and cancer. Magnetic Resonance Imaging (MRI) is advantageous for quickly proliferating leiomyomas that are difficult to visualize with Ultrasonography (US) and when there is a suspicion of malignancy.…”
