FAMILIAL TRIAD OF ANORECTAL, SACROCOCCYGEAL, AND PRESACRAL ANOMALIES THAT INCLUDES SACROCOCCYGEAL TERATOMAS

We present two Australian families with the triad of anorectal, sacroc occygeal, and presacral anomalies. In one family four members had sacr al deformities, three of which were associated with presacral masses a nd anal stenosis. The presacral masses were: one meningocoele combined with a teratoma; one teratoma; and the third remains undiagnosed and unresected at the patient's request. In the second family, one child h ad an infected presacral teratoma with a small sacral defect and the f ather had a similar sacral defect with computed tomographic evidence o f a presacral meningocoele and teratoma. The presence of anal stenosis and constipation with a sacral defect should raise the possibility of a presacral mass. The mass may take the form of a meningocoele, terat oma, enteric cyst, or any combination of these. Once detected, other f amily members should be investigated.
