Primary lymphomas of the female genital tract: imaging findings

Primary lymphomas of the female genital tract are extremely rare, and a definitive diagnosis requires correlation of the clinical, radiological, and pathological findings. Unlike nonlymphomatous malignant tumors, the treatment of lymphoma is typically nonsurgical, thus raising the possibility of lymphoma in the differential diagnosis of a pelvic mass, a radiologist can significantly change the approach to the disease. Although some imaging findings may appear nonspecific, others may suggest the possibility of lymphoma, such as the presence of one or more solid, well-defined, homogeneous masses without necrosis despite a large size or the presence of diffuse infiltration leading to organomegaly with architectural preservation. Additionally, pelvic lymphadenopathy may be evident. In this pictorial essay, we discuss the radiological appearances of gynecological primary lymphomas, grouped by organ, in ultrasonography, computed tomography, and magnetic resonance imaging.

Algoritmo de abordagem das lesões anexiais indeterminadas na ecografia

O esclarecimento do órgão de origem, ou principalmente da natureza benigna ou maligna de um tumor anexial ecograficamente indeterminado surge com frequência na prática clínica e obriga a uma investigação complementar da sua natureza de modo a evitar cirurgias inúteis, sem deixar de diagnosticar precocemente a patologia maligna. Neste trabalho apresentamos um algoritmo de diagnóstico por Ressonância Magnética (RM), que recentemente foi proposto pela European Society of Urogenital Radiology (ESUR), o qual permite um diagnóstico preciso dos casos indeterminados à ecografia e uma intervenção responsável na abordagem clínica destas doentes.
