Clinical examination revealed that all masses were soft, movable and well defined (Fig. 1).
(A) Sagittal T1-weighted MRI revealed a homogenous low intermediate signal intensity mass, surrounded by a low signal intensity well-marginated capsule in the subcutaneous fat of the posterior neck. (B) Axial T2-weighted MRI images showed an oval mass with high signal intensity and debris with low signal intensity at the surrounding capsule.

T1-weighted images, while in T2-weighted images, its signals were of high signal intensity with multiple occurrences of focal low signal intensity debris (Fig. 2). The masses in the left upper back (13x12x6 cm) and the left scalp (5x5x4 cm) were diagnosed as subcutaneous lipomas based on MRI findings.
Mass in the posterior neck was well defined with an elastic texture and contained a cream-colored fluid with a butter-like consistency.

The mass in the posterior neck was well defined with an elastic texture and contained a cream-colored fluid with the consistency of butter (Fig. 3).
Histopathological examination showed the epidermal cyst wall with a thin layer of benign stratified squamous epithelium and lamellated keratin debris present in the cyst (H&E-stained; original magnification, x20).
