Lateral semicircular canal dilatation in a patient with congenital hearing loss due to α-tectorin mutation: microanatomical considerations.

The tectorial membrane is crucial in the physiology of the auditory neuroepithelium. Mutations in one of its functional molecules, α-tectorin, lead to autosomal dominant and recessive congenital mid-frequency, non-syndromic hearing loss.Typically, α-tectorin mutations are not accompanied by any morphological abnormalities of the labyrinth.

Distal mechanical thrombectomy for very eloquent M3 branches with a new, adjustable diameter clot retriever: A technical note.

Distal thrombectomy may be considered in selected patients harboring acute occlusion of distal arterial branches, supplying very eloquent brain areas. In these cases navigation and deployment in tortuous, fragile and very small-caliber arteries is usually involved, potentially increasing the risk of per-procedural vessel wall perforation. We report a case of distal recanalization in a right-handed, fourty-year-old woman with left M3 occlusion, with the use of a novel device with manually adapted, gradual expansion, navigated through a 0.

A Ptolemaic mummy reveals evidence of invasive dentistry in ancient Egypt.

Over the last decades, it has been confirmed that computerized tomography (CT) is a valuable tool for studying mummies. In joint efforts put forth by the Mummy Research Project of the Hellenic Institute of Egyptology, the National Archaeological Museum, and the Athens Medical Center, a mummy was transported to the Radiology Department of the Athens Medical Center for study. Thus, a complete CT scanning was performed of this Ptolemaic mummy (AIG 3343: Sekhem, male, 150-30 BCE), belonging to the Egyptian Collection of the National Archaeological Museum of Athens.

Chronic maxillary atelectasis under the wrappings of an Egyptian mummy.

Objectives: In the context of a joint Mummy Research Project of the National Archaeological Museum, the Hellenic Institute of Egyptology and the Athens Medical Centre, an Egyptian mummy of the mid-Ptolemaic Period was transferred to our hospital and was thoroughly investigated with Computed Tomography.

Methods: The mummy was carefully removed from its coffin and scanned in a 64-detector row computed tomographic scanner. Multiplanar and anthropometric measurements were obtained using advanced software.

Intravenous and Intracavitary Use of Contrast-Enhanced Ultrasound in the Evaluation and Management of Complicated Pediatric Pneumonia.

Pediatric pneumonia can be complicated by necrotizing pneumonia or a parapneumonic effusion either in the form of an empyema or a clear effusion. Ultrasonography (US) and computed tomography represent well-established modalities for evaluation of complicated pediatric pneumonia. Contrast-enhanced ultrasound (CEUS) was recently introduced and is gaining increasing acceptance in pediatric imaging.

Ectopic Intrathyroidal Thymus in Childhood: A Sonographic Finding Leading to Misdiagnosis.

Background: During gestation, the primordial thymus migrates from the pharynx to the anterior mediastinum, thus thymic tissue can remain at any point along this path. Intrathyroidal thymic remnants are rare, and their sonographic patterns have only recently been described. This retrospective study presents the sonographic appearance of ectopic intrathyroidal thymus and emphasizes the role of sonography in order to avoid misdiagnosis.
