Diplegia in the legs
Diplegia of the legs consists of paralysis of both legs. There are 3 levels of severity. Mild diplegia means the person can usually walk but might walk a little differently, can usually play and run to a limited extent. Moderate diplegia means the person can usually walk but with a slight bend in the knees. They usually cant run and have to use the handrails to go up and down steps. People with severe diplegia usually need crutches, a walker, or a wheelchair to be able to get around.Children with diplegia in the legs have a delayed growth in their leg muscles which causes the muscles to be short. This then causes the joints to become stiff and the range of motion to decrease as the child grows. “For the majority of children with diplegia, growth and development are not a problem. Children with diplegia are eventually able to walk, just normally later; they generally attend regular schools and become independently functioning adults.”

Causes
The most common cause of diplegia in the legs is cerebral palsy. Paralysis of the legs may also be caused by trauma, injury, or genetics, but this is very rare. Age of onset
Usually occurs within 2 periods:
With premature babies
full diagnosis usually between ages 2–5 yearsDiplegia is usually not diagnosed before the age of 2 years yet the symptoms and signs of the earlier stages are typical and should enable the diagnosis to be made before the contractures have occurred.
Alternatively, enlarged lymph nodes may represent a primary malignancy of the lymphatic system itself, such as lymphoma (both Hodgkins and non-Hodgkins), lymphocytic leukemia, Lymphadenopathy that lasts less than two weeks or more than one year with no progressive size increase has a very low likelihood of being neoplastic.Metastatic lymph nodes are enlarged because tumor cells have detached from the primary tumor and started growing in the lymph node ("seeded"). Since cancer generally occurs more frequently in older people, this kind of lymphadenopathy is more common in older persons. Metastatic lymph nodes tend to feel hard and may be fixed to underlying tissues and may or may not be tender. Usually the lymph nodes that directly drain the area of the cancer are affected by the spread (e.g. Sometimes metastatic cervical lymph node is detected before the main cancer). In such cases, this discovery leads to a search for the primary malignancy, firstly in the nearby area with endoscopy, "blind" biopsies, and tonsillectomy on the side of the lymphadenopathy. If no tumor is found, then the rest of the body is examined, looking for lung cancer or other possible sites. If still no primary tumor is detected, the term "occult primary" is used.In lymphoma, usually there are multiple enlarged nodes which feel rubbery to palpation. Rhabdomyosarcoma
Neuroblastoma
