Case 3. Case 3. A 10-year-old boy with sublingual swelling shows partial shrinkage after 3 OK-432 injections.A and B, The initial contrast-enhanced CT scan shows cystic lesions in the right sublingual space (arrows) and submental space (arrowheads).C and D, Unenhanced CT scan taken 2 months after the first sclerotherapy, depicts disappearance of the cyst in the right sublingual space (arrow), but a cyst remains in the submental space (arrowheads). The ranula in the submental space recurred after its complete shrinkage after the next 2 OK-432 injections. M.H. Rho et al.
