Learning objectives

To review the common and uncommon gluteal lesions. To illustrate key radiological findings which could guide a correct diagnosis.

Background

The gluteal region is subject to a wide variety of disorders as it consists of different layers and tissues. A pictorial review of the common and uncommon gluteal region anomalies is presented. Diagnostic imaging plays an important role in assessment, in which the differential diagnosis is mainly based on the tissue of origin and specific imaging characteristics. Magnetic resonance imaging(MRI), computed tomography(CT) as well as angiography are used to depict characteristic radiological findings, guiding a correct diagnosis and appropriate treatment.

Findings and procedure details

The gluteal region consists of skin, subcutaneous layer, blood vessels, muscle, neural tissue, and bones. A pictorial review of 12 patients aged from 40 to 85 with gluteal mass lesion was presented, in the order of superficial to deep layers. Skin and subcutaneous layer Epidermoid cyst Epidermoid cyst(Fig.1) is a common cutanoues lesion that consist of proliferation of squamous epithelium within a confined space. It often develops spontaneously by occlusion ofpilosebaceous unitbut can also be caused by trauma.On MR images, its content is typically T1...

Conclusion

Radiologists play an important role in assessing the gluteal lesions of patients.Awareness of the clinical context, knowledge on common and uncommon gluteal abnormalties and their characteristic imaging features are essential to make a correct diagnosis and guide appropriate treatment.
