This lesion was detected by WBS and confirmed by surgery and histopathologic analysis.

However, the clinical characteristics of false-negative Tg cases with positive WBS have not been clarified.

We encountered two WBS patients presenting with infantile spasms, which is extremely rare in WBS.

Larger case series are needed to further characterize the correlation between WBS and acute coronary events.

In light of this result, an ultrasound scan confirmed the presence of well-characterized features of WBS.
