Initial MRI study demonstrates an epidermoid situated in the fourth
ventricle. The epidermoid restricts diffusion, is heterogeneous on sagittal
T1, axial T2 weighted and FLAIR images and does not enhance (yellow
arrows).. MRI, magnetic resonance imaging.

A 42-year-old male with a clinical history of Gardner syndrome and multiple sclerosis underwent magnetic resonance imaging (MRI) evaluation which revealed a 1.8 cm heterogeneous mass without enhancement within the fourth ventricle (Figure 1).
MRI performed 6 years following the initial study reveals interval growth of
the epidermoid cyst (yellow arrows).. MRI, magnetic resonance imaging.

The mass restricted diffusion and was followed subsequently by the Department of Neurosurgery (Figure 2).
Follow up MRI performed 10 years following initial study reveals progressive
enlargement of the epidermoid cyst. The lesion restricts diffusion, is
heterogeneous on T2 weighted and flair images and does not enhance (yellow
arrows).. MRI, magnetic resonance imaging.

The mass demonstrated progressive enlargement and, at 10 years, now measures 2.7 cm in greatest dimension (Figure 3).
