While RAD-140 and MK-677 have not been previously linked to splenic pathology, their pharmacological effects on androgen receptor signalling and IGF-1 pathways warrant consideration as possible contributing factors, particularly in the context of a suspected pre-existing vascular malformation. Early recognition, aggressive resuscitation, and timely surgical intervention remain critical, as delayed diagnosis carries significant mortality. This evidence concerns the gene IGF1 and vascular malformation.
