Magnetic resonance imaging manifestations and pathological features of primary ovarian leiomyoma in four cases / 中国基层医药

ABSTRACT

Objective:To investigate magnetic resonance imaging (MRI) findings of primary ovarian leiomyoma (POL) and improve the understanding of the disease.Methods:The clinical data of four cases of POL confirmed by surgical pathology who received treatment in Huadu District People's Hospital between September 2006 and August 2018 were retrospectively analyzed. MRI manifestations and pathological features of POL were analyzed.Results:In four cases, POL occurred in unilateral ovarium and appeared to be a single quasi round mass with complete capsule and clear boundary. A solid mass was observed in three cases and a cystic solid mass in one case. Subcapsular effusion was observed in three cases with a relatively large tumor body. Typical MRI findings were iso-intensity or slight hypo-intensity signal on T 1WI, hypo-intensity signal on T 2WI and diffusion-weighted images. The solid part on enhanced scan was enhanced synchronously with the uterus. Atypical T 2WI findings included cystic changes as shown by varying degrees of hyper-intensity signal, and the cystic change area was not enhanced. The internal signal and pathological features of POL were similar to those of uterine leiomyoma. Conclusion:The research results are highly innovative and scientific. MRI is of great significance in the diagnosis and differential diagnosis of POL.
