A twelve-year-old male child presented to neurology outpatient department with complaints of developmental delay, intellectual impairment, weakness in both lower limbs, ataxia and abnormal facies (Figure 1) (Previously, the patient had consulted a local practitioner in his village, but no imaging was performed.
Median sagittal reformatted section of computed tomography of the brain showing hypoplastic vermis with dilated fourth ventricle and deep interpeduncular fossa.

Non-contrast computed tomography of the head showed hypoplastic vermis with a dilated batwing-shaped fourth ventricle (Figures 2 and 3A). The size of the posterior fossa and corpus callosum was normal (Figure 2).
Axial sections of computed tomography of the head showing a dilated batwing-shaped fourth ventricle, hypoplastic vermis (A), and thickened and elongated superior cerebellar peduncles (A, B) with deep interpeduncular fossa (B) giving a "molar tooth sign" (A, B).

Non-contrast computed tomography of the head showed hypoplastic vermis with a dilated batwing-shaped fourth ventricle (Figures 2 and 3A). The isthmus was hypoplastic with deep interpeduncular fossa, thickening and elongation of the superior cerebellar peduncle giving "molar tooth" sign (Figure 3A, 3B).
Sagittal reformatted section of computed tomography of the brain showing thickened superior cerebellar peduncles oriented horizontally.
