Imaging Characteristics

Increased use of Diffusion-weighted imaging (DWI) in acute stroke has led to observations of early diffusion normalization in lesions thatinitially show diffusion slowing. The “renormalization” of DWI may be spontaneous or the result of thrombolytic therapy, thus, acuteslowing of diffusion is not necessarily an indicator of irreversible tissue damage. The perfusion-diffusion mismatch concept is attractiveas it assumes that DWI lesion size reflects the infarct core whilst the mismatch area reflects the penumbra. However, this concept maybe an oversimplification. This paper shows a case with Diffusion Lesion Reversal after successful neuroendovascular treatment andexcellent clinical outcome, and discuss the imaging characteristics associated with this phenomenon.

Background: Lymphoma of the female gynecologic tract is extremely rare. Typically, lymphoma is managed non surgically unlike other non-lymphomatous malignant tumors raising the importance to differentiate between both entities. Case report: We describe the magnetic resonance imaging (MRI) features of a case of uterovaginal diffuse large B-cell lymphoma in a 50-year-old postmenopausal woman emphasizing Diffusion-Weighted Imaging (DWI) as a diagnostic and follow up tool. We reviewed the literature regarding the diagnostic methods for female genital lymphoma. Forty-five cases including our patient were reviewed with age range from 22 to 85 years. Vaginal bleeding was the most common presentation. The diagnosis was established by Papanicolaou smear, cervical biopsy (25/45), endometrial biopsy (6/45), vaginal biopsy (2/45), pelvic mass biopsy (2/45), iliac LN biopsy (1/45) and surgical diagnosis (8/45). Diffuse large B-cell lymphomas (DLBCL) constitute the vast majority of the cases (82%). The uterine cervix was involved at diagnosis in the majority of these cases (68%) while uterine body (42%) and vagina (28%) were less involved. Pelvic lymphadenopathy was found in 15 cases while extra genital lymphomatous infiltration in 13 cases. Sonographic findings were nonspecific while CT provided excellent data about extra-genital involvement. Thirteen cases underwent pelvic MRI that displayed superior detection of disease extension and parametric involvement. Diffusion restriction was reported only in one case without quantitative analysis of ADC map. Conclusion: MRI shows unique features that help to differentiate uterovaginal lymphoma from the much more common carcinomas and discriminate post-operative changes from tumor recurrence. It exhibits a marked restricted diffusion pattern with lower ADC values than carcinomas and post-operative changes.
