    abstract = {Endometriosis is a chronic, estrogen‐dependent condition that affects
10–15% of reproductive‐aged women and up to 50% of those with
infertility. While classical pelvic endometriosis is well studied, rare and
atypical presentations such as polypoid endometriosis, deeply infiltrating
endometriosis (DIE), and extrapelvicmanifestations remain
underdiagnosed. MRI has emerged as a reliable, non‐invasive modality for
evaluating both typical and atypical forms of the disease. This
observational study was conducted at Sree Mookambika Institute of
Medical Sciences, Tamil Nadu, from August 2024 to February 2025. Thirty
women, aged 20‐45 years with suspected or confirmed endometriosis
underwent MRI evaluation. Imaging protocols included T1‐weighted (with
and without fat suppression), T2‐weighted, and diffusion‐weighted
sequences. MRI findings were correlated with clinical symptoms and,
when available, histopathological confirmation. The most common
clinical symptoms were dysmenorrhea (83.3%), dyspareunia (50%), and
infertility (40%). MRI revealed T2 shading in 66.7% of cases, T2 dark spot
sign in 50%, DIE in 60%, andextrapelvic lesions in 16.7%. Frequent lesion
sites included the ovaries (73.3%), rectosigmoid colon (26.7%), diaphragm
(10%), and abdominal wall (6.7%). Histopathology confirmed fibrotic
nodules (60%) and hemorrhagic foci (40%). MRI effectively demonstrated
lesion composition, distribution, and treatment response. MRI is a
powerful tool for identifying rare and atypical endometriotic
presentations. Integrating advanced imaging protocols can improve
diagnostic accuracy, reduce delays, and enhance surgical planning and
treatment monitoring.}
