- A case of sclerosing angiomatoid nodular transformation of the spleen: Imaging and histopathological findingsPublication . Eusébio, Marta; Sousa, Ana Lucia; Vaz, Ana Margarida; da Silva, Silvia Gomes; Milheiro, Maria Adelaide; Peixe, Bruno; Caldeira, Paulo; Guerreiro, HorácioA 62-year-old woman presented with left upper quadrant pain and anorexia for 1 month. She had a past medical history of nephrolithiasis, extramembranous glomerulonephritis and a relevant atopic background. Physical examination as well as laboratory tests were unremarkable. Abdominal computed tomography, performed without endovenous contrast due to patient’s atopic history, highlighted a nodular density between the pancreatic tale and splenic hilum. On unenhanced magnetic resonance imaging this corresponded to a vascular structure, next to the spleen, with a ‘‘serpentine’’ shape and apparently in continuity with this organ. Additionally, within the spleen there were three, well circumscribed, macronodular lesions, with lobular borders, the biggest measuring 2.5 cm in greater diameter. These lesions were isointense on T1-weighted sequences and hypointense with mildly hyperintense septa on T2 and FATSAT Fiesta sequences. No other relevant lesions were identified.
