Central venous stenosis or occlusion is commonly associated with placement of central venous catheters or devices. Although rare, central venous stenosis or occlusion may also develop without a history of previous central venous catheter placement. Here we report a case of central venous stenosis without a previous central catheter placement. A 76-year-old woman with hypertensive nephropathy was admitted due to deterioration of renal function. Tunneled cuffed catheter for hemodialysis was inserted in the right external jugular vein, and we intended to insert central venous catheter because of poorly functioning peripheral vein. But, left internal jugular vein was not cannulated. The patients had a history of pulmonary tuberculosis and chest x-ray revealed extensive calcified lesions mainly in left upper lung. Venography and CT angiogram showed complete occlusion at the confluent point of the left subclavian vein and left internal jugular vein, and left brachiocephalic vein by calcified lesion. The anterior cervical vein and jugular venous arch forming an anastomosis between the neck vein were marked dilated. The patient did not show any clinical symptoms and signs associated with central venous stenosis, and the central venous catheter functioned well, correction of central vein stenosis was not necessary. After the supportive care including temporary hemodialysis, the patient improved from renal dysfunction.

Ameloblastoma is the most common aggressive benign odontogenic tumor of the jaws. Because of slow growth and tendency to local invasion of bone and soft tissue, high rates of recurrence are common. The treatment for ameloblastoma is still controversial and poses some special problems in children. Because of growth of the jaw and the different incidence, prognosis of the tumor make the surgical consideration different from adults. Radical resection cause facial deformity, jaw abnormal movement and masticatory disturbance especially to child and adolescents. So conservative treatment as enucleation, curettage is acceptable initial treatment of ameloblastoma in children who can be followed up in a precise, detailed manner. This report describes a case of unilocular plexiform ameloblastoma treated by enucleation and curettage followed by marsupialization.
