Reversible Ortner's Syndrome as a Presenting Feature of Thyrotoxicosis in an Adolescent: A Rare Case Report.

Ortner's or cardiovocal syndrome is hoarseness attributable to left recurrent laryngeal nerve (RLN) palsy associated with mechanical compression of the nerve by pathologically enlarged cardiovascular structures. Ortner's syndrome is a rare condition, and to our knowledge, only a few cases have been reported in Korea. Furthermore, this condition is extremely uncommon in pediatric patients with thyrotoxicosis-related RLN paralysis.

[Delayed Bilateral Common Femoral Pseudoaneurysm after Percutaneous Access with Interventional Management: A Case Report].

Common femoral artery pseudoaneurysm is a potentially serious complication of peripheral angiography.

Deep convolutional neural network for the diagnosis of thyroid nodules on ultrasound.

Background: We designed a deep convolutional neural network (CNN) to diagnose thyroid malignancy on ultrasound (US) and compared the diagnostic performance of CNN with that of experienced radiologists.

Methods: Between May 2012 and February 2015, 589 thyroid nodules in 519 patients were diagnosed as benign or malignant by surgical excision. Experienced radiologists retrospectively reviewed the US of the thyroid nodules in a test set.

Bilateral diffuse tumorous pseudoangiomatous stromal hyperplasia treated with bilateral mastectomy in a 40-year-old woman.

Pseudoangiomatous stromal hyperplasia (PASH) is a rare benign breast disease characterized by breast stromal proliferation mimicking low grade angiosarcoma. PASH is frequently detected as an incidental component coexisting with other breast lesions. However, it can also present as a single localized mass and is typically unilateral.

Spectrum of imaging findings of chronic granulomatous disease: a single center experience.

The purpose of this pictorial essay is to present and summarize findings of various images of chronic granulomatous disease (CGD). CGD represents a heterogeneous group of disorders caused by defective generation of respiratory bursts in human phagocytes. This defect results in abnormal phagocytic functions and defective killing of bacteria by phagocytes.
