Partial CPT was defined as "lacking substantial shared dural venous sinuses", whereas total CPT "share a large portion of their dural venous sinuses and present with pronounced brain compression, which leads to distortion within the cranium". Total
Total craniopagus twins share a large portion of dural venous sinuses and present with pronounced brain compression, leading to distortion within the cranium. Stone and Goodrich also defined two main subtypes, based on whether the long-axis angle between the twins was angular or vertical. The angular subtype has a higher rate of comorbidities than the vertical subtype.Vertical craniopagus calvaria is continuous and is further subdivided on the basis of intertwin axial facial rotation:

Type 1: both children face in the same general directional axis so that the angle between twins is less than 40 degrees. These twins show relatively symmetric superior bi-parietal or vertex compressional flattening. Type 2: both children face opposite directions so that the deformity shows an axial rotation between 140 and 180 degrees.
Pustular bacterid is a skin condition characterized by a symmetric, grouped, vesicular or pustular eruption on the palms and soles marked by exacerbations and remissions over long periods of time. : 205
