An unusual case of hydranencephaly presenting with an anterior midline cyst, a posterior calcified mass, cerebellar hypoplasia and occlusion of the posterior cerebral arteries.

We present an unusual case of severe hydranencephaly in a term infant who presented with the following additional unique features, which were discovered on CT, MRI and MR angiography examinations: (1) occlusion of the bilateral posterior cerebral arteries, (2) absence of the occipital lobes, (3) an ovoid calcified mass sitting on the inner table of the occipital bone, (4) severe cerebellar hypoplasia, (5) a dysmorphic cystic diencephalon, (6) a large anterior midline cyst just above the cribriform plate and (7) absence of the falx. These imaging findings were confirmed at autopsy.

The neurology of benign paroxysmal torticollis of infancy: report of 10 new cases and review of the literature.

Benign paroxysmal torticollis is an under-recognized cause of torticollis of early infancy. The attacks usually last for less than 1 week, recur from every few days to every few months, improve by age 2 years, and end by age 3. There very frequently is a family history of migraine. We did a detailed analysis of 10 cases of benign paroxysmal torticollis, seen over 5 years, and compared our findings with those in the 103 cases in the literature. Detailed neurodevelopmental assessments, available only in our cases, showed accompanying gross motor delays in 5/10 children, with additional fine motor delays in 3/5. As the benign paroxysmal torticollis improved, so did the gross motor delays in 3/5, and the fine motor delays in 1/3. In all of our cases, at least 2 other family members had migraine. Benign paroxysmal torticollis is likely an age-sensitive, migraine-related disorder, commonly accompanied by delayed motor development.
