"Rarely, there is an association with Hajdu-Cheney syndrome, which is characterised by hirsutism, joint laxity, acro-osteolysis, vertebral anomalies, bathrocephaly, and normal intelligence 4."
"Bathrocephalic occiputs is a normal variation in skull shape, in which there is an outward convex bulge of mid-portion of the occipital bone 5. Bathrocephaly extends from the lambdoid to the mendosal suture. There is often a significant bulge of the interparietal portion of the occipital bone 3,6."
"There is no evidence that intervention or surgical management of the disorder is necessary 1."
