[Value of muscular echography in the detection of carriers of progressive muscular dystrophy].

Progressive muscular dystrophy is an hereditary disease with a sex-linked recessive transmission. It is remarkable that in a 33% of the patients the disease is due to a spontaneous mutation. The great deal of methods described for the detection of carriers, reflects their poor reliability.

[Semilobar holoprosencephaly associated with central diabetes insipidus].

The clinical and neuroradiological findings in a case of semilobar holoprosencephaly associated to hypernatremia behaving like diabetes insipidus are described. The differential diagnosis with a neurogenic hypernatremia is discussed. The advantages of ultrasounds in the diagnosis of this malformation are pointed out.

Spontaneous hematomas caused by microangiomatosis of the basal ganglia. Presentation of two cases in the newborn period.

We present 2 cases of tumors of the gray basal nuclei with intraventricular hemorrhage and secondary hydrocephalus. Because of the patients' ages, the absence of traumatic antecedents and the angiographic characteristics, the findings were diagnosed as gliomas. In both cases, the existence of hematomas provoked by microangiomatosis was proved after the operation.
