Zusammenfassung
Bei einem 16-jährigen Mädchen wurde eine intrathyroidal gelegene Zyste festgestellt, die sich histologisch als ektopes Thymusgewebe herausstellte. Die Feinnadelbiopsie hatte keine eindeutige Diagnose gebracht, ebenso wenig mehrfache Ultraschallkontrollen. Die ektope Lage des Thymus in der Schilddrüse ist eine ungewöhnliche Seltenheit.
