Ninety-three patients were included in the study. Nineteen patients with semicircular canal dehiscence were detected. The mean age of the study group was 45 years. Radiologic evidence of SSCD occurred in 23 of 186 temporal bones with a radiologic prevalence of 12%. The most common symptoms in dehiscent patients were vertigo, hearing loss and tinnitus. Defect lengths varied between 1 mm and 6.5 mm.

Vascular lesions of the head and neck include vascular neoplasms, vascular malformations, and hypervascular lesions, derived from nonvascular soft-tissue elements. We retrospectively evaluated magnetic resonance imaging and computed tomography images of vascular lesions located in the head and neck. Twelve patients (seven males, five females) aged 1-68 years (mean age, 35.25 years) were included in this study. Most of the vascular lesions in our study were histologically diagnosed. The lesions were as follows: a hemangioma located in the parotid space (n=1); a hemangioendothelioma located in the parotid space (n=1); a hemangiopericytoma located in the larynx (n=1); a juvenile angiofibroma located in the nasopharynx (n=1); a glomus tumor located in the carotid bifurcation (n=1); venous malformations located in the parapharyngeal space, the pterygoid area, the orbital space, and the larynx (n=4); lymphatic malformations located in the parotid space and the supraclavicular area (n=2); and an arteriovenous malformation located in the infratemporal fossa (n=1). We present rare vascular lesions of the head and neck, which have typical radiological findings.

AIm: Intrasutural bones are often found within sutures and fontanelles of the skull. It is important that the anatomy of these bones in the field of non-accidental injury with respect to medicolegal complications. Skull fracture lines are critical in their differential diagnosis, and the features of bone formations, their appearance and position give us a more definitive diagnosis. mATERIAL and mETHods: Intrasutural bone location, its number and symmetry were investigated in totally 300 adult skulls.REsuLTs: 27 intrasutural bones were identified as interparietal (2%), preinterparietal (3%) and sutural bones (4%) were in the lambdoid sutures. It was detected that the interparietal and preparietal bones were single, and the sutural ones were in a multiple number. The sutural bones were superposed in significant structures such as sagittal sinus and sinus sigmoideus. CoNCLusIoN:The ones that should be paid attention to in the differential diagnosis of the skull fracture lines are preinterparietal and interparietal bones in larger sizes. These findings prompted us to report these cases as their presence can lead to confusion in diagnosis in cases of skull fractures. BuLGuLAR: 27 tane sütüral kemik tanımlandı: interparietal (%2), preinterparietal (%3) ve sütüral kemik (%4) tanımıyla lambdoid sütür kemiği. Interparietal ve preparietal kemikler tek, sütüral olanları ise çok sayıda idi. Sütüral kemikler aynı zamanda sagittal sinüs ve sigmoid sinüs gibi önemli yapıların üzerine yerleşmiş idi. soNuÇ: Preparietal ve interparietal kemiklerin daha büyük boyutlarda olması kırık hattı ayırıcı tanısında dikkat edilmelidir. Bu olgularda elde ettiğimiz kemiklerin, tanıda kafa kırıkları ile karışabileceği yönündedir.

A 45-year-old man presented with dyspnea on exertion, fatigue, and cough. Transthoracic echocardiography showed a large apical thrombus in the left ventricle. The laboratory results showed prominent eosinophilia on blood smear, elevated acute phase reactants and D-dimer serum levels. Bone marrow examination showed a Fip1-like platelet-derived growth factor receptor alfa fusion gene mutation. The case was diagnosed as myeloproliferative variant hypereosinophilic syndrome. Contrast-enhanced computed tomography demonstrated thrombi not only in left ventricle but also in multiple segmental pulmonary arteries. Cardiac magnetic resonance imaging showed left ventricular apical thrombus without subendocardial fibrosis. Cardiopulmonary manifestations of hypereosinophilic syndrome completely resolved after treatment.
