Traumatic diaphragmatic rupture (TDR) is uncommon, and may be associated with other severe life-threatening injuries after blunt trauma. Recently, we experienced a right-sided TDR patient with other multiple life-threatening injuries. A 59-year-old female inflicted with a right-sided TDR accompanied by herniated liver was treated with thoracoscopic exploration. We successfully managed associated life-threatening injuries such as traumatic brain injury and pelvic bone fractures with bleeding, simultaneously.

Spindle epithelial tumor with thymus-like differentiation (SETTLE) is a very rare tumor of the thyroid gland mostly occurring in young patients. The imaging findings of SETTLE tumors are yet to be defined. However, they are usually described as well-defined heterogeneously enhanced masses on CT scan. The current case has the potential growth as compared with a 2009 chest radiography. We took into account the possibility of SETTLE in the case of a bulky mass in patients over 70 years old, particularly in the lower neck...
