DISCUSSION
Ectopic thymic tissue is a rare clinical entity that can occur in the
neck, lung, pleura or another location in the thoracic
cavity.78 Bilateral cervical ectopic thymus has also
been reported.13 From our systematic review, 192
paediatric cases were identified with 150 with sufficient data to be
analysed in the last 20 years. We will discuss the challenges regarding
both the diagnosis and management of ECT based of the current available
evidence.
