Size of mamillary
bodies in health and disease: Useful measurements in neuroradiological diagnosis of Wernicke's encephalopathy.
MRI scan revealed a T1 and T2 weighted isointense and FLAIR slight hyperintense mass lesion in Hypothalamic Tuber Cinerium region with extension of lesion into right mamillary
Brain structures such as the periaqueductal nuclei, mamillary
bodies and thalami with high metabolic requirements are especially vulnerable to thiamine deficiency.
Furthermore, with the block in position, the spinous, lamina or mamillary
processes can be contacted to rotate the vertebra opposite to the direction indicated by the cervical vertebra transverse process sensitivity.
While hyperintensity is seen in medial thalamic and periacuaductal gray matter on T2 and FLAIR sequences of cranial Magnetic Resonance Imaging (MRI) in acute cases, atrophy in mamillary
bodies, enhanced signaling in the base of fourth ventricle, midline of cerebellum may be seen in chronic cases and contrast enhancement may occur in mamillary
bodies and inferior quadrigeminal region (4,5).
Avian eggshell consists of the innermost bilayered membranes, a calcified layer composed of a mamillary
and pallisade layer, and the outermost cuticle.
Each fascicle arises from a common tendon attached to the spinous process of individual lumbar vertebrae with fascicles attaching to the mamillary
process of the inferior vertebrae, the iliac crest and the sacrum (Macintosh and Bogduk 1986).
50) In a study of the brains of 49 patients who had died at least 4 days after an event of severe hypoxia, the findings demonstrated that the morphological changes in the mamillary
bodies due to thiamine deficiency and those due to hypoxia-ischemia may be identical.
However, there was a redemonstration of increased T1 signal seen within the bilateral basal ganglia and relative diminutive appearance to the bilateral mamillary
bodies, which suggests possible liver disease and/ or alcohol abuse.
