Lingula of cerebellum (I)

The lingula is a small, tongue-shaped lobe of the superior vermis of the cerebellum, located immediately anterior to the central lobule and superior medullary velum. It forms the most anterior part of the superior vermis and is continuous laterally with the culmen of the anterior lobe. The lingula is composed of cerebellar cortex (gray matter) overlying white matter and participates in coordination of postural reflexes and balance, as part of the vermal functional system.

It is anatomically significant due to its proximity to the fourth ventricle and superior medullary velum, making it an important landmark in posterior fossa imaging, neurosurgery, and cerebellar lesion localization. The lingula is narrow, elongated, and tongue-shaped, distinguishing it from adjacent lobules of the vermis.

Function

  • Contributes to postural coordination and balance control

  • Integrates signals from the vestibular system and spinal cord

  • Participates in fine-tuning of axial musculature

  • Works with other vermal lobules to maintain equilibrium during movement

Synonyms

  • Cerebellar lingula

  • Lingula vermis

  • Superior vermis tongue-shaped lobule

MRI Appearance

T1-weighted images:

  • The lingula appears as gray matter with intermediate signal intensity, overlying hyperintense white matter in the cerebellar vermis

  • The cortical-subcortical junction is well-delineated

  • Pathological lesions such as infarcts, demyelination, or tumors alter normal signal intensity

T2-weighted images:

  • Cortical gray matter of the lingula appears intermediate to slightly hyperintense

  • Underlying white matter is low-to-intermediate signal, providing contrast

  • T2 is useful for identifying edema, gliosis, or cerebellar pathology

STIR (Short Tau Inversion Recovery):

  • Gray matter shows mild hyperintensity, white matter is suppressed

  • Edema, inflammation, or small lesions appear bright, enhancing detection of subtle abnormalities

T1 Post-Contrast (Gadolinium-enhanced):

  • Normal lingula shows no significant enhancement

  • Lesions such as neoplasms, vascular malformations, or inflammatory processes demonstrate variable enhancement, highlighting abnormal tissue

CT Appearance:

  • The lingula is not easily distinguished on non-contrast CT due to similar density of gray matter and surrounding cerebellar tissue
