Background
Various pathologic masses which include congenital (spinal dysraphism,
tailgut cyst,
sacrococcygeal teratoma etc),
infectious and neoplastic condition (sacrococcygeal canal tumors and bone tumors) can occur in the sacrococcygeal area.
But,
these lesions may present a diagnostic challenge due to low incidence rate and delayed nonspecific symptoms,
such as lower back pain,
radiculopathy.
