Condensing pediculolaminar hypertrophy of mechanical origin is known as "Dahu's sign". Dahu's sign corresponds to hypertrophy of the vertebral hemi-arch found by CT scan and leads to suspicion of controlateral lysis of the isthmus. It is the CT scan equivalent of vertebral "anisocorism" by conventional radiology.
