Cutis Verticis Gyrata

Cutis verticis gyrata is a condition of the scalp, seen most commonly in African American males, which causes furrowing and ridging of the scalp.  It can be primary, or secondary to a zillion different conditions, most importantly insulin resistant conditions and chronic pulmonary disease.  .  The giveaway on this guy is the clear ridge/furrow pattern to the scalp, something recognizable in spite of the overexposure.  It was described by Alibert, and there's an extra bonus point for ya if you can tell me the hospital with which Alibert was associated.
