The patient underwent NVC which showed granular flow, dyshomogeneous capillary morphology, increased efferent/afferent loop ratio, many enlarged capillaries sized between 20 and 50 microm, loss of alignment and not uniform distribution of capillaries, characteristics compatible with a non-specific pattern (Figures 2-5(Fig. 2)(Fig. 3)(Fig. 4)(Fig. 5)).
