Mario Bertolotti (1876-1957) was an Italian radiologist.
Bertolotti trained as a neurologist, and went on to become a full professor of radiology later in life. His monograph Roentgen Craniology Lessons (1920); studies on pneumoencephalography (1934) and internal frontal endocraniosis were widely respected and he is considered the founder of Italian neuroradiology
Bertolotti, best known for his work concerning the articulation between the L5 transverse processes and sacrum, which he described in a 1917 article

Bertolotti syndrome (1917)
Sacralisation of the lower lumbar vertebrae. Partial or complete fusion of the transverse process of the L5 vertebra to the sacrum. Associated with scoliosis and symptoms of low back pain and sciatica. It can be unilateral or bilateral.
Bertolotti Syndrome is an atypical cause of low back pain or buttock pain caused by a transitional lumbar vertebrae with a large, “spatulated” transverse process that either fuses with the sacrum (sacral ala) or ilium, or forms a pseudo-articulation at that location (Seen on a lumbar spine AP X-ray).
This is a congenital abnormality, but doesn’t usually become symptomatic until a patient’s 20’s or 30’s.
