Ganglioneuroma is a rare tumor in the posterior mediastinum; fat-containing ganglioneuromas are rarely reported. The present case report documents a brown fat-containing, posterior mediastinal ganglioneuroma, which has not been reported previously. Radiological examination, in particular 18F-2-fluoro-2-deoxyglucose-positron emission tomography, suggested that the tumor had low-grade malignant potential. This led to uncertainty at preoperative diagnosis. ⋯ Histological diagnosis of the surgically resected mass confirmed ganglioneuroma with substantial amounts of white and brown adipose tissues in peripheral areas. The existence of both ganglion cells and brown fat tissue intensified the accumulation of 18F-2-fluoro-2-deoxyglucose, resulting in a false-positive result by positron emission tomography. Considering this, ganglioneuroma should not be excluded either clinically or pathologically in fat-containing, posterior mediastinal tumors.

The frequency of vertebrobasilar ischemia in patients with cervical spine trauma had been regarded as low in many published papers. However, some case reports have described cervical spine injury associated with blunt vertebral artery injury. Many aspects of the management of vertebral artery injuries still remain controversial, including the screening criteria, the diagnostic modality, and the optimal treatment for various lesions. The case of a patient who had a brain infarction due to recanalization of his occluded vertebral artery following open reduction of cervical spinal dislocation is presented here. ⋯ The management of asymptomatic vertebral artery injury is controversial with several treatment options available, including observation alone, antiplatelet therapy, anticoagulation therapy, or invasive intervention. Although there are some reports in which management with observation alone is described as safe, we should pay serious attention to the vertebral artery injury caused by cervical spine trauma.

Case Reports
Jehovah's Witness patients presenting with ruptured ectopic pregnancies: two case reports.
The management of emergencies in Jehovah's Witnesses presents several challenges to obstetricians and gynaecologists. We present two cases of ectopic pregnancies in Jehovah's Witnesses recently managed in our institution. This is the first case review series of its kind that we could identify. We feel it is of clinical importance for all physicians caring for Jehovah's Witnesses. ⋯ We feel that this case review series emphasises the importance of appropriate management of Jehovah's Witnesses in our units. In both of the above cases, these women were in potentially life-threatening situations. Advances in haematology and pharmaceutical therapy contributed to their survival. We welcome these advances in the treatment of this patient population.

Differential diagnosis of thrombotic microangiopathies can be difficult. Atypical hemolytic uremic syndrome is a rare, life-threatening disease caused by uncontrolled chronic activation of alternative complement pathway, resulting in microvascular thrombosis, organ ischemia and damage. Prognosis is poor: up to 65 percent of patients require dialysis or have kidney damage of varying severity or die despite plasma exchange/plasma infusion treatment. ⋯ Establishing the diagnosis of atypical hemolytic uremic syndrome in patients presenting with thrombotic microangiopathy is challenging since common symptoms are shared with other conditions like Shiga toxin-producing Escherichia coli hemolytic uremic syndrome and thrombotic thrombocytopenic purpura. The described case illustrates the complexity and importance of rapid diagnosis in a rare disease and the need for appropriate and specific treatment for best long-term outcomes.

Case Reports
Autoimmune pulmonary alveolar proteinosis co-existing with breast cancer: a case report.
Pulmonary alveolar proteinosis is a rare pulmonary disease characterized by excessive alveolar accumulation of surfactant due to defective alveolar clearance by macrophages. There are only a few published case reports of pulmonary alveolar proteinosis occurring in association with solid cancers. To the best of our knowledge, there are no previously reported cases of pulmonary alveolar proteinosis associated with breast cancer. ⋯ The present case involved the coincident occurrence of autoimmune pulmonary alveolar proteinosis with breast cancer; breast cancer may be a factor during pulmonary alveolar proteinosis development.
