TY - CHAP M1 - Book, Section TI - Joubert Syndrome A1 - Bissonnette, Bruno A1 - Luginbuehl, Igor A1 - Engelhardt, Thomas Y1 - 2019 N1 - T2 - Syndromes: Rapid Recognition and Perioperative Implications, 2e AB - A genetic disorder characterized by cerebral malformations (vermis and brain stem) resulting in severe coordination (ataxia) and breathing (sleep apnea, hyperpnea) disorders. This medical condition is present during infancy and is characterized by cerebellar ataxia, hyperpnea, sleep apnea, abnormal eye, tongue movements, and myotonia. There is a significant range of mental retardation. The presence of the “molar tooth sign” found in the MRI, in which the cerebellar vermis of the brain is absent or underdeveloped whereas the brain stem is abnormal, is very informative and the Joubert Syndrome must be considered in the differential diagnosis.
