Overview
Sacrococcygeal teratoma (SCT) is classified into 4 different categories according to Altman classification.[1]

Altman are classified morphologically according to how much of them is outside or inside the body:
- Altman Type I - extensively exterior with minimal pelvic involvement.[1]
- Altman Type II - has pelvic involvement giving tumorous growth an "hour-glass" appearance.
- Altman Type III - has more pelvic and intra-abdominal involvement than external.
- Altman Type IV - extensive pre-sacral involvement without external growth.
