ABSTRACT

OBJECTIVE: Chronic Pelvic Pain (CPP) presents significant diagnostic challenges, often involving multiple pathologies, including endometriosis and pelvic venous disorders. This study examined the prevalence of endometriosis among women with confirmed pelvic varicosities.

METHODS: The authors performed a retrospective analysis of 52 women with CPP and pelvic varicosities who underwent multiparametric magnetic resonance venography between January 2019 and December 2023. All images were reviewed by a single experienced radiologist, blinded to clinical data and vascular findings, to identify radiological signs of endometriosis.

RESULTS: Among the 52 women, 32 exhibited radiological findings consistent with endometriosis, corresponding to a prevalence of 61.5% (95% CI: 47.0%-74.5%).

CONCLUSION: This study demonstrates a high prevalence of endometriosis among women with pelvic varicosities. Multiparametric MRI proved effective as a non-invasive diagnostic modality capable of identifying both vascular and gynecologic abnormalities in a single session, supporting integrated assessment approaches for women with CPP. Limitations include the retrospective design and the lack of histological confirmation of endometriosis.

Comput Med Imaging Graph. 2026 Feb 26;129:102736. doi: 10.1016/j.compmedimag.2026.102736. Online ahead of print.ABSTRACTLayer-wise segmentation of three-dimensional (3D) ultrasound for chronic lower back pain (cLBP) requires a large amount of labeled images. To mitigate this burden, we propose a Generative Reinforcement Network (GRN) that integrates a generative adversarial network (GAN) framework

The activation of p66shc in the Prelimbic Cortex contributes to the development of neuropathic pain

Online ahead of print.ABSTRACTThis study investigated the role of the adaptor protein p66shc in the prelimbic cortex (PrL) in neuropathic pain development in rats. Results showed that activated p66shc and reactive oxygen species (ROS) were elevated in the PrL following peripheral nerve injury. Intra-PrL administration of p
