BACKGROUND: High riding jugular bulb (HRJB) develops after 2 years and is rare at younger ages. High riding jugular bulb sometimes protrudes into the tympanic cavity, which can cause hemorrhagic complications during otologic surgery.
CASE PRESENTATION: We describe a congenitally deaf child with bilateral inner ear malformations and a right-sided HRJB on CT at 9 months. This child had undergone left cochlear implantation (CI) at 19 months, and right CI was planned at 6 years. However, we decided not to perform the right CI because preoperative CT images revealed that the right jugular bulb (JB) was enlarged and protruded into the tympanic cavity, completely covering the round window (RW).
CONCLUSION: This is the first pediatric case in which a longitudinal CT scan proves that HRJB develops and protrudes over time. These findings suggest that the earlier the HRJB forms, the larger it may grow. We must keep in mind the possibility of the enlargement and protrusion of HRJB.
