low back pain and paraplegia as initial clinical presenting of medulloblastoma: a case report

Introduction: medulloblastoma is one of the most common malignancies in children. common clinical symptoms of patients are related to the symptoms due to tumor in the posterior cranial fossa. presentation of patients with symptoms related to metastatic tumors in the spinal canal are unusual. case presentation: we present a 6-year-old child with symptoms of lower back pain and paraplegia as early symptoms of medulloblastom. the magnetic resonance image (mri) of spinal cord revealed multiple tumors in the spinal canal (initially diagnosed). a biopsy of the tumor was also performed. then, whole cns (central nervous system) imaging revealed tumor in the posterior cranial fossa. he had a dramatic improvement after treatment and returned to normal in all clinical signs. four years have passed from his treatment and he is symptom free. conclusions: presentation of medulloblastoma with widespread spinal canal drop metastases is rare. however, spinal drop metastasis should be considered to prevent a suboptimal management in child. these patients did not consider in aspect of the treatment outcome as hopeless.
