There was slightly high signal in T2W, heterogeneous enhancement in arterial phase, persistent enhancement in delayed phase, high signal presented in DWI, and reduced ADC (Figure 1).
Histology of the cervical small cell carcinoma (X200). There was hypercellularity and scanty stroma. The cells were arranged in ribbons, lines, or waves, which are typical of small cell carcinomas.
