Management of Proximal Thoracic Kyphoscoliosis with Early Myelopathy in a Young Adult with Neurofibromatosis Type 1: A Case Report and Review of Literature.

Introduction: Neurofibromatosis (NF) 1 is associated with skeletal deformities. Scoliosis is seen in about 10-64% of NF-1 patients. NF-1 may be associated with dystrophic or non-dystrophic type of curve.

Locally aggressive aneurysmal bone cyst of C4 vertebra treated by total en bloc excision and anterior plus posterior cervical instrumentation.

We are presenting a case of cervical (C4) aneurysmal bone cyst in a 13-year-old girl, came to the outpatient department with neck pain and stiffness since 6 months and normal neurology. We did an en bloc excision of locally aggressive tumor through anterior plus posterior approach and stabilization by lateral mass screw fixation and anterior cervical instrumentation. Involvement of several adjacent cervical vertebrae by an aneurysmal bone cyst is rare, and conventional treatment with curettage and bone grafting is most likely to carry a high rate of recurrence and spinal instability.
