Isolated primary bony lymphoma of the spine is exceedingly rare. Bone as the primary site of lymphoma occurs in 1% of all non-Hodgkin's lymphoma. Primary vertebral locations are seen in 1.7% of all primary bony lymphomas. Anaplastic Large Cell Lymphoma (ALCL) is very rare. We diagnosed the patient as a case of Anaplastic Lymphoma Kinase (ALK-1) positive ALCL by immunohistochemistry on a surgical specimen. Post-operative MRI of the spine as well as PET scan revealed residual active disease. Patient received combination chemotherapy with radiotherapy. He showed an excellent response in the form of improvement in paraparesis and good quality of life. Though this was a rare type of lymphoma with rare location, combined modalities of therapy resulted in a satisfactory outcome.Keywords

Most of the sensor nodes in a Wireless Sensor Network (WSN) have limited energy. Enhancing energy efficient algorithms to increase the WSN lifetime is of researcher’s interest for the past two decades. The present study demonstrates the data routing method from node to BS (Base Station) using two cluster heads to prolong the battery life of sensor nodes. The double cluster head analogy reduces the overhead of cluster head, avoids packet collision, and improves reliable data transmission with little compromise in energy consumption and hop count compare to single cluster head method. The present study demonstrates the data routing method using Energy efficient Surface water Wireless Sensor Network (ES-WSN) Algorithm for reliable operation of wireless sensor network. If single cluster head is used for both collecting the information from the nodes as well as communicating with BS, there would be countable packet loss, resulting in more processing time, and adequate reformation of clusters. To avoid the drawbacks of single cluster head method second cluster head is selected to provide link between first cluster head and BS.
