Table 2 Radiological characteristics of sclerosing angiomatoid nodular transformation reported in the literature
Previous reports
Radiological characteristics
Li et al[8] Low density with small calcification on plain CT scan and progressive enhancement of the lesion after enhancement
Zeeb et al[18] Edge enhancement in arterial and portal phases. A stellate low-density region can be seen in the center of the delayed phase of the lesion
Thacker et al[19] Persistent stellate low-density areas can be seen in the center of the lesion
Bamboat et al[20] MRI T2-WI showed that the center of the lesion was stellate and low-density, and it appeared as a spoked-wheel configuration
Karaosmanoglu et al[21] MRI and CT enhancement patterns of marginal enhancement and progressive spoked-wheel enhancement towards the center of the lesion
Nomura et al[12] CT: Lesion is well circumscribed and of lower attenuation compared to the background spleen, and the mass becomes isodense in the delayed phase.MRI: On fat-saturated precontrast T1-weighted images SANT presented as a central hyperintense area consistent with hemorrhage, and on T2-weighted images, the lesion appeared as a spoke and wheel pattern.
