Abstract:
A 13 year-old girl presented with back pain and recurrent falls of one year, with more recent loss of ambulation and bladder control. Examination showed spasticity and a sensory level bilaterally at T8. CT and MRI scans showed an epidural soft tissue mass with spinal cord compression and destruction of the pedicle, transverse process and other portions of a mid-thoracic vertebral body. Histologic examination of the gross total resection showed a pigmented villonodular synovitis (PVNS). PVNS is most common in the knee and only 26 cases have been reported in the spine. Although vertebral bodies are rarely involved, it is important to include PVNS in the differential diagnosis of spinal lesions because of its tendency to recur locally if not totally resected.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
