Ductal carcinoma in situ (DCIS) falls into a heterogeneous group of tumors, whose diagnosis has increased with the use of mammography as screening method. The Van Nuys Prognostic Index, mainly based on histological nuclear grade and presence of necrosis, is the most reproducible histopathological classification system. The most common abnormality observed during a mammography are microcalcifications, which coexist with other lesions such as masses and architectural distortion, and represent low-grade lesions. The initial diagnosis should be performed by anamnesis and a detailed physical examination to help determine the morphostructural characteristics of the lesion. Then an imaging and dynamic approach should be achieved by magnetic resonance imaging (MRI) complemented by immunohistochemistry to characterize the tumor. The presence of morphological segmental distribution is typical of m...

Posterior Reversible Encephalopathy Syndrome (PRES) is a clinical and radiological condition given by neurologic signs along with characteristic imaging findings. During pregnancy, its presentation is associated to Eclampsia. We present the case of an 18-year-old patient who develops treatment refractory eclampsia and HELLP syndrome during immediate puerperium, thus leading to the diagnosis of PRES and referral to intensive care. Imaging assessment confirmed diagnosis, with successful results. PRES consists of a heterogeneous group of pathologic processes, triggered by multiple etiologies, in our case secondary to hypertensive encephalopathy caused by Preeclampsia-Eclampsia Syndrome. Association of PRES, Preeclampsia-Eclampsia Syndromeand HELLP such as the case of our patient, is extremely rare with limited amount of case reports.
