Imaging of Chiari Type I and Type Ii Malformations
نویسندگان
چکیده
Chiari malformations (CM) are a group of posterior fossa abnormalities affecting the cerebellum, brainstem and the spinal cord. An in-depth understanding of the radiological findings is highly imperative for the early accurate diagnosis of CM in the developing fetus and the adult alike. We report here a case each of Type I and II CM presenting with the classical MRI imaging findings of CM Type I in a 38-year-old lady with complaints of a headache, seizures and loss of sensation in the lower limbs. And Arnold Chiari Type II during routine antenatal ultrasonographic screening in a 30-year-old primigravida at 17 weeks and 3 days of gestation respectively.

The brain and spinal cord were examined with MR imaging in 30 myelomeningocele patients 3-32 years old to study the prevalence of syringohydromyelia and Chiari malformations and to correlate these conditions with developmental scoliosis and spontaneously arrested hydrocephalus. Twelve patients had neurologic deficits above the level of the myelomeningocele and 10 had spontaneously arrested hydr...
