    To assess symmetrical increased echogenicity of bilateral caudothalamic grooves (SIEBCG) detected on newborn cranial ultrasonography (CUS) using magnetic resonance susceptibility-weighted imaging (SWI). A total of 14 newborns (8 girls; 12 premature with mean gestational age of 30 weeks and 5 days, 2 mature) who were detected to have SIEBCG on routine serial CUS and underwent cranial magnetic resonance imaging (MRI) were recruited for the study. The cranial MRI examinations including SWI acquired on the same day of SIEBCG detection and serial CUS to assess the progress of SIEBCG lesions in the following 6 month period were retrospectively evaluated and compared for the presence of germinal matrix hemorrhage. On SWI, solely one patient (7, 1%) had signal alteration on caudothalamic groove compatible with grade 1 germinal matrix hemorrhage. Two patients (14, 2%) had parenchymal (on cerebellar and parietal white matter) millimetric hemorrhagic foci. Seven patients (50%) had signs of presumptive hypoxic insult including hyperintense dots on centrum semiovale and periventricular white matter in five, and increased signal intensity on the globus pallidi in two, on T1-weighted images. Four patients (28, 6%) had normal findings. Of these, 10 patients became normal on follow-up CUS at postterm-equivalent age, whereas four were missing. Symmetrical increased echogenicity of bilateral caudothalamic grooves seen on newborn CUS may be the indicator of other pathologies as ischemic insult or focal parenchymal hemorrhage. In the presence of SIEBCG, further examination with SWI should be performed.

    Sonography in the Diagnosis of Congenital Adrenal Hyperplasia in a Neonate
    (Aves Press Ltd, 2017) Koc, Gonca; Doganay, Selim; Dogan, Mehmet Sait; Gorkem, Sureyya; Coskun, Abdulhakim
    Congenital adrenal hyperplasia (CAH) is a relatively rare inherited disease that primarily affects the synthesis of steroid hormones by the adrenal glands. Patients usually present in the weeks following birth with salt wasting and virilization. In patients who are clinically suspected, a definitive diagnosis is established with the detection of increased levels of precursor hormones. An evaluation of the adrenal glands by ultrasonography may help make an accurate diagnosis of CAH prior to a biochemical confirmation. We report the case of a neonate with 21-hydroxylase deficiency who was diagnosed with the typical appearance of the adrenal glands for CAH revealed with ultrasonography.
