Sacral dimples are often spotted in post-natal checks by pediatricians, [3] [5] who can check: whether the floor of the dimple is covered with skin; whether there is a tuft of hair in the dimple; whether there are potentially related problems such as weak lower limbs; the distance from the buttocks to the dimple (closer is better).
Diastematomyelia is a "dysraphic state" of unknown embryonic origin, but is probably initiated by an accessory neurenteric canal (an additional embryonic spinal canal.).) This condition may be an isolated phenomenon or may be associated with other segmental anomalies of the vertebral bodies such as spina bifida, kyphoscoliosis, butterfly vertebra, hemivertebra and block vertebrae which are ...
Many individuals may exhibit EEG, CT, or MRI abnormalities. Hyporeflexia, gait abnormalities, and truncal or symmetric limb hypotonia were observed in at least 15% of individuals in a cohort of 136 16p11.2 deletion carriers. [5] Sensorineural or conductive hearing loss and paroxysmal kinesigenic choreoathetosis are observed in some individuals.
MRI imaging appears to be the gold standard for diagnosing a tethered cord. [16] [17] A tethered cord is often diagnosed as a "low conus". The conus medullaris (or lower termination of the spinal cord) normally terminates at or above the L1-2 disk space (where L1 is the first, or topmost lumbar vertebra). After about 3 months of age, a conus ...
Microcephaly is a disorder in which the fetus has an atypically small head, [62] cerebral calcifications means certain areas of the brain have atypical calcium deposits, [63] and meningoencephalitis is the enlargement of the brain. All three disorders cause abnormal brain function or intellectual disability.
If a deletion includes the TCF4 gene (located at 55,222,331-55,664,787), features of Pitt-Hopkins may be present, including abnormal corpus callosum, short neck, small penis, accessory and wide-spaced nipples, broad or clubbed fingers, and sacral dimple. Those with deletions inclusive of TCF4 have a significantly more severe cognitive phenotype.

The first study of the human brain at 3.0 T was published in 1994, [13] and in 1998 at 8 T. [14] Studies of the human brain have been performed at 9.4 T (2006) [15] and up to 10.5 T (2019). [16] Paul Lauterbur and Sir Peter Mansfield were awarded the 2003 Nobel Prize in Physiology or Medicine for their discoveries concerning MRI.
