Retrorectal dermoid cyst in a male adult: case report.
We describe a 48-year-old male patient who presented with rectal fullness and pain. Magnetic resonance imaging (MRI) and computed tomographic studies revealed a noncalcified, unilocular, cystic mass lesion with well-defined borders. On MRI nondependent fat spheres were detected inside the cyst. The same pattern has been described in dermoid cyst of the ovary. We suggest that this MRI pattern is specific to dermoid cysts.
