[The interesting case -- case no. 67].

Background: Lipoma of the retropharyngeal space is a rare benign tumour often showing unspecific clinical symtoms. It can grow to an enormous extent causing total obstruction of the upper respiratory tract. Until now its etiology is unknown. With a variety of differential diagnoses, a diagnostic concept is necessary.
Case Report: A 41 year old male patient complained about a nondolent swelling of the neck. The radiological diagnostics showed a huge lipoma of the para- and retropharyngeal space with subtotal obstruction of the pharynx. The lipoma was removed completely via transcervical approach.
Conclusion: Lipoma as differential diagnosis of retropharyngeal tumours always has to be considered. Surgical intervention is recommended. To prevent functional complications resulting from tumour and surgery and to get information about the extent of the lipoma, accurate radiological imaging is mandatory.
