Migration of a Globefish Bone to the Sternocleidomastoid Muscle: Case Report

Fishbones are the most common upper aerodigestive and esophageal foreign body found in adults. Usually these bones pass, but when complications arise, they can be catastrophic and may include neck abscesses, mediastinitis, and esophago-aortic or esophagocarotid fistulas. We report the radiologic findings of fishbone injury occurring in a 48-year-old man in whom a globefish bone had penentrated the hypopharynx and migrated to the sternocleidomastoid muscle.

Dedifferentiated Liposarcoma in the Thigh: Case Report

Dedifferentiated liposarcoma occurs in less than 10% of all liposarcoma and is found most often in the retroperitoneum and extremities. Histologically, the tumor was composed of well-defferentiated liposarcomastous areas with malignant fibrous histiocytoma-like area, peculiar neurallike whirling pattern associated and focal metaplastic bone formation. The rare radiologic feature of this have not been sufficiently described in the previous literature, and we now report a case of dedifferentiated liposarcoma in the thigh.

A Case of Severe Asthma Complicated with Pneumoperitoneum and Pneumomediastinum During AMBU Ventilation / 결핵

Pneumoperitoneum, Pneumomediastinum, subcutaneous emphysema and a pneumothorax are some of the mechanical complications of bronchial asthma. The incidence of pneumoperitoneum during an attack of acute asthma is rare. The pathogenesis is free gas track from the overdistended alveoli, through the bronchovascular sheaths to the mediastinum. If the high pressure is maintained, air can escape retroperitoneally into the abdomen and burst into the peritoneal cavity. A 43-year-old woman was admitted due to a severe asthma attack. She was required endotracheal intubation and AMBU(air mask bag unit) ventilation. Immediately after these procedures, pneumoperiotneum, pneumomediastinum, and subcutaneous emphysema daveloped. She was treated with mechanical ventilation and medical therapy. The pneumoperitoneum was resolved after 27 days. Here, we report this case with the review of the relevant literature.
