Prenatal Ultrasonographic Molar Tooth Sign: Case Reports and Review of Literature

Journal of Fetal Medicine, 2021
AbstractJoubert Syndrome and Related Disorders (JSRD) refers to all disorders presenting as “molar tooth sign” (MTS) on brain imaging. Fetuses with JSRD present with relatively nonspecific signs on prenatal ultrasound varying from increased nuchal translucency, enlarged cisterna magna, cerebellar vermian agenesis, occipital encephalocele ...

Early Second-Trimester Molar Tooth Sign

Fetal Diagnosis and Therapy, 2014
Molar tooth sign (MTS) is pathognomonic for Joubert syndrome (JS) and related disorders. We report a case in which MTS was suspected in an ‘at risk' patient at 16 weeks' gestation by sonography and at 18 weeks by additional ultrasound. It was then confirmed at 20 weeks by MRI.

A 15-Year-Old Boy With Snoring and Molar Tooth Sign

Chest, 2015
A 15-year-old boy presented for evaluation of snoring and sleep-disordered breathing. The parents noted that the patient snored every night and that he had episodes when he stopped breathing, ending with gasping for air. He had no history of sleep walking, night terrors, tongue biting, or seizures.

The molar tooth sign

Neurology, 2008
Joubert syndrome and related cerebellar disorders (JSRD) are a group of recessive congenital ataxia conditions usually showing neonatal hypotonia, dysregulated breathing rhythms, oculomotor apraxia, and mental retardation. The pathognomonic finding in JSRD is the unique molar tooth sign (MTS) on brain imaging.

Molar Tooth Sign and Superior Vermian Dysplasia: A Radiological, Clinical, and Genetic Study

Neuropediatrics, 2006
We have identified a group of 13 patients with a homogeneous radiological pattern at MRI consisting of the molar tooth sign (MTS) and superior vermian dysplasia. The patients represent a relatively heterogeneous clinical group with variable severity of developmental delay, ataxia, hypotonia, and apnea.

Molar Tooth Sign in Joubert Syndrome: Clinical, Radiologic, and Pathologic Significance

Journal of Child Neurology, 1999
Joubert syndrome is a rare autosomal-recessive condition characterized by early hyperpnea and apnea, developmental delay, and truncal ataxia. We previously described key ocular motor signs in Joubert syndrome and the molar tooth sign resulting from dysplasia of the isthmic segment of the brain stem, superior cerebellar peduncles, and vermis.

Molar tooth sign of the midbrain–hindbrain junction: Occurrence in multiple distinct syndromes

American Journal of Medical Genetics Part A, 2003
AbstractThe Molar Tooth Sign (MTS) is defined by an abnormally deep interpeduncular fossa; elongated, thick, and mal‐oriented superior cerebellar peduncles; and absent or hypoplastic cerebellar vermis that together give the appearance of a “molar tooth” on axial brain MRI through the junction of the midbrain and hindbrain (isthmus region). It was first
