In the 2016 World Health Organization renal tumor classification, the mixed epithelial and stromal tumor family was introduced as a new entity. This family encompasses a spectrum of tumors, ranging from predominantly cystic tumors (adult cystic nephromas) to tumors that are variably solid (mixed epithelial and stromal tumors). The majority of previous studies incorporating "mixed epithelial and stromal tumor" in the titles were actually reports of imaging findings of adult cystic nephroma.

- The study aimed to analyze the MRI features and staging of neuroendocrine carcinoma (NEC) of the uterine cervix, while also examining the relationship between pathology and survival rates.
- Findings indicated that most cases showed a slightly high signal intensity and restricted diffusion in MRI scans, with a high overall accuracy of 88% for staging when compared to pathology results.
- The research revealed that fewer patients with advanced stages (III and IV) had favorable survival outcomes, with significant recurrence rates observed during the follow-up period.
An intrahepatic portosystemic venous shunt is a relatively rare abnormality that can cause encephalopathy owing to hyperammonaemia. Two patients with encephalopathy owing to intrahepatic portosystemic venous shunts were treated with transcatheter emboli sation using the AMPLATZER Vascular Plug II. Both patients achieved complete obliteration, which was confirmed on dynamic CT.
