Abstract

Background: A calcifying nested stromal-epithelial tumour (CNSET) is an erratic primary liver malignant tumour frequently discovered in young girls and females. Neither its pathogenesis nor its nosogenesis is clearly known. While principally indolent, infrequent tumours with aggressive clinical progression have been defined. This paper describes a CNSET case with rare clinical and imaging features.

Case presentation: A 17-year-old girl initially presented with enlarged lymph nodes near the main portal vein of the liver and a large liver tumour. Lesions were identified on the imaging findings obtained via positron emission tomography-computed tomography (CT) scanning, including an abnormal increase of heterogeneous glucose metabolism in the intrahepatic mass, with a maximum standardised uptake value of around 3.2. The CT imaging showed multiple dense shadows in the lesion, while the magnetic resonance imaging indicated a long T1 and a slightly longer T2.

Conclusions: This study summarises the imaging features of CNSETs to provide a reference for diagnosing liver tumours. In addition, the literature on the topics covered was systematically reviewed.

Keywords: Calcifying nested stromal-epithelial tumours; computed tomography; differential diagnosis; nuclear magnetic resonance imaging; positron emission tomography/ computed tomography.
