Myocardial bridging in adult with hypertrophic cardiomyopathy: Imaging findings with coronary computed tomography angiography.

Myocardial bridgin in an adult with hypertrophic cardiomyopathy is a rare congenital coronary artery anomaly. It is often detected incidentally, and its true incidence in the general population is not known. Myocardial bridging may cause compression of a coronary artery, and it has been suggested that myocardial ischemia may result.

Imaging features of sublingual dermoid cysts: a report of four cases.

Dermoid cysts of the floor of the mouth are rare lesions presumed to be caused by entrapment of germinal epithelium during the closure of the mandibular and hyoid branchial arches. They usually manifest as nonpainful swelling. Developmental cysts are histopathologically classified into 3 types: epidermoid, dermoid, and teratoid.

Frequency of complications and risk factors associated with computed tomography guided core needle lung biopsies.

Background: Although transthoracic needle biopsy (TTNB) is an effective method for diagnosis of lung tumors, it has some complications. It is crucial to know the frequency and severity of the complications of TTNB and its risk factors in order to avoid them.

Objectives: Evaluate the complications and risk factors of computed tomography guided core needle lung biopsies (CT-CNLB).

The diagnostic value of 4D MRI at 3T for the localization of parathyroid adenomas.

Purpose: The aim of this study was to assess the feasibility of four-dimensional magnetic resonance imaging (4D MRI) at 3 T for the localization of parathyroid adenomas.

Materials And Methods: Preoperative 4D MRI scans, encompassing dynamic contrast-enhanced (DCE) sequences and non-contrast enhanced (non-CE) sequences, including a T2-weighted multipoint Dixon (T2-mDixon) sequence, with in-phase, out-phase, and water-only images, were evaluated retrospectively in 41 patients with surgically proven parathyroid lesions. Two readers who were blinded to the surgical findings independently reviewed the images in two sessions (non-CE sequences alone and non-CE + DCE sequences).

Multimodality imaging of a rare type of coronary cameral fistula.

Coronary artery fistulas are defined as abnormal vascular connections between one or more coronary arteries and the cardiac chamber [coronary cameral fistula (CCF)] or a great thoracic vessel. Here, we present multimodality imaging findings of a rare case with CCF between the sinoatrial nodal artery and the left atrium.

Association between facial nerve second genu angle and facial canal dehiscence in patients with cholesteatoma: evaluation with temporal multidetector computed tomography and surgical findings.

Introduction: Otitis media, mastoiditis or the pressure effect of tumorous lesions such as cholesteatoma can be the cause of facial canal dehiscence and facial nerve paralysis. The most common segment involved in dehiscence is the tympanic segment and the second most common is the lateral aspect of the facial canal in the oval window area.

Objective: To determine the prevalence of the facial canal dehiscence and the relationship between the angle at the second genu of the facial nerve and facial canal dehiscence.

The diagnostic value of shear wave elastography for parathyroid lesions and comparison with cervical lymph nodes.

Aims: The aim of this study was to prospectively assess the feasibility of the Virtual Touch tissue imaging quantification (VTIQ) method of shear wave elastography (SWE) for the discrimination of parathyroid lesions and to compare the lesions' stiffness with that of cervical lymph nodes.

Materials And Methods: SWE using VTIQ was performed on 66 patients with 87 histopathologically proven parathyroid lesions (54 parathyroid adenomas and 33 parathyroid hyperplasia) and 29 patients with 31 inflammatory cervical lymph nodes. The mean SWVs of the lesions were compared and receiver operating characteristic (ROC) curve analysis was used to evaluate diagnostic performance.

Calcification of the submandibular gland in a patient with chickenpox.

The pneumonia virus of chickenpox is now known to cause scattered calcified foci in the lungs, however to our knowledge, recent literature has not discussed calcification in the salivary glands. A 15-year-old boy consulted the department of radiology because of a swelling on the right side of the submandibular area. Radiological assessment included an ultrasonography and computerized tomography scan of the neck area, which demonstrated intraparenchymal amorph calcification, with approximately 13 mm diameter in the right submandibular gland.

The diseases of airway-tracheal diverticulum: a review of the literature.

Tracheal diverticulum (DV) is a type of paratracheal air cyst (PTAC) that is often asymptomatic and usually detected incidentally by imaging methods. Tracheal DV are divided into two subgroups: congenital and acquired. Dysphagia, odynophagia, neck pain, hoarseness, hemoptysis, choking, and recurrent episodes of hiccups and burping can also be seen in symptomatic patients.

Palate Lymphoma: CT Findings.

Objective: Non-Hodgkin lymphomas (NHL) in the palate are very rare. We aimed to investigate the CT appearance of lymphoma in the palate to improve diagnostic quality and review the literature on NHL.

Materials And Methods: The study retrospectively included patients with histopathologically confirmed lymphoma who were treated at our hospital between 2008 and 2015.

Paratracheal air cysts: prevalence and correlation with lung diseases using multi-detector CT.

Introduction: The purpose of this study was to determine the prevalence of paratracheal air cysts (PACs), their correlation with different lung diseases and their connection with the trachea by chest multi detector computed tomography (MDCT).

Methods: We retrospectively reviewed chest MDCT images of 8240 consecutive patients obtained from January 2010 to December 2011 with a 16-detector multi-detector CT scanner. PACs were assessed for prevalence, location, level, size and the presence of visible communication with the trachea.

Postoperative lung volume change depending on the resected lobe.

Objectives: The aim of this study was to evaluate the lung volume changes depending on the resected lobes. The changes were quantitatively evaluated using stereological methods on computed tomography images and by pulmonary function tests (PFTs).

Methods: The study subjects included 30 patients who underwent lung resection.

The effect of minimally invasive surgical repair on the lung volumes of patients with pectus excavatum.

Objectives: To assess the increase in lung volume after Nuss surgery in patients with pectus excavatum (PE) by using stereological methods and to evaluate the correlation between the lung volume and spirometry findings.

Methods: Twenty patients, treated for PE between 2008 and 2010, were evaluated prospectively. They underwent preoperative chest radiography, computed thorax tomography (CTT), and spirometry.

Descending necrotizing mediastinitis associated with an infected dentigerous cyst.

Descending necrotizing mediastinitis (DNM) is a rare condition in which an infection from the head and neck propagates into the mediastinum. The most common cause of DNM is odontogenic infection. DNM is spread by the fascial planes from the neck into the mediastinum and requires an aggressive surgical drainage through cervical and thoracic approaches.

Pulmonary actinomycosis mimicking chest wall tumor in a child.

Actinomycosis is an uncommon disease in children and most cases are cervicofacial infections. To date, there have been only a few reports on children with chest wall involvement due to actinomycosis. Here we report a 9-year-old girl with a mass lesion in the chest wall mimicking Ewing's sarcoma of the rib.

Value of Doppler sonography in assessing the progression of chronic viral hepatitis and in the diagnosis and grading of cirrhosis.

Objective: The purpose of this study was to evaluate the value of Doppler sonography in assessing the progression of chronic viral hepatitis and in the diagnosis and grading of cirrhosis.

Methods: Abdominal sonographic and liver Doppler studies were performed in 3 groups: 36 patients with chronic viral hepatitis, 63 patients with cirrhosis, and 30 control subjects with no evidence of liver disease. A series of Doppler indices of hepatic vascularity, including portal vein velocity, portal vein pulsatility score, flow volume of the portal vein, resistive and pulsatility indices of the hepatic artery, modified hepatic index, hepatic vascular index, waveform of the hepatic vein, and focal acceleration of flow, were measured and correlated with liver and spleen size, portal and splenic vein diameter, and presence of ascites and collateral vessels.
