Intramuscular Infiltrating Lipoma of the Longus Colli Muscle. A very rare cause of Neck Structures Compression

Introduction

Lipomas are the most common benign soft tissue mesenchymal tumors. They are usually located in the subcutaneous layer without infiltrating adjacent tissues [12]. Infiltrating lipomas, by contrast, are uncommon entities that characteristically infiltrate skeletal muscles with a propensity for local recurrence if they are incompletely excised [1]. These infiltrating lesions can be subclassified into intermuscular and intramuscular lipomas [5] [11] [12]. We describe the case of a large intramuscular lipoma of the right longus colli muscle located at the level of C2-C5. Although other reports of retropharyngeal space lipomas exist [7] [13] [18] [20] [24], ours seems to be the first case of a longus colli intramuscular lipoma described in the English literature since 1988 [7].
