Posterior fossa horns; a new calvarial finding of mucopolysaccharidoses with well-known cranial MRI features.

Background/aim: Mucopolysaccharidoses (MPS) are a group of hereditary metabolic diseases. The aim of this study was to share the previously unreported calvarial finding of internal hypertrophy of the occipitomastoid sutures (IHOMS) together with some other well-known cranial MRI findings in this patient series.

Materials And Methods: A retrospective evaluation was conducted of 80 cranial MRIs of patients who had been diagnosed and followed up with MPS from 2008 to 2019 in our center.

Persistent craniopharyngeal canal, bilateral microphthalmia with colobomatous cysts, ectopic adenohypophysis with Rathke cleft cyst, and ectopic neurohypophysis: case report and review of the literature.

Introduction: Persistent craniopharyngeal canal (PCC) is a rare anomaly of the base of the skull. PCC is defined as a well-corticated osseous canal, extending from the roof of the nasopharynx to the base of the sella over the course of the sphenoid corpus. We reported a PCC case with unique associations.

Association between deep neck space abscesses and internal carotid artery narrowing in pediatric patients.

Background/aim: Our aim was to interpret the effects of deep neck space abscesses on the adjacent carotid artery according to abscess location, as well as to determine narrowing by calculating the mean stenosis ratios.Materials and methods: Neck computed tomography scans and clinical data of 45 children with neck abscesses were evaluated retrospectively for abscess location and internal carotid artery narrowing. The lumen areas of the carotid arteries were measured from standard levels, and stenosis ratios were calculated with two different techniques.

Hepatic Complications of Umbilical Venous Catheters in the Neonatal Period: The Ultrasound Spectrum.

Objectives: Umbilical venous catheterization is commonly used in the neonatal period; however, it has some complications. In this study, we evaluated neonates who underwent umbilical venous catheterization and developed hepatic complications. Furthermore, we aimed to define all of the possible lesions and to clarify the imaging findings of umbilical venous catheter-induced hepatic injury.

A Newborn with an Alternative Porto-Caval Shunt.

Background: Absent ductus venosus (ADV) is a rare condition, but it should be known that this embryonic anomaly may be detected by fetal echocardiographic or newborn ultrasound examinations.

Case Report: We present a baby with an ADV and an accompanying alternative porto-caval shunt between the right portal vein and inferior vena cava detected on postnatal ultrasound examination.

Conclusions: Variations in the fetal umbilical or porto-systemic circulations should be detected by fetal or newborn ultrasound examinations and kept in mind before common interventions such as UV catheterizations.
