Malignant neoplasm of unspecified main bronchus [C34.00], Reason for Study: ^Reason: metastatic lesions History: back pain Cervical spineThere bone marrow replacing enhancing lesions involving C7 left side facet joints and lamina as well as T1 vertebral body indicating metastatic lesions.There is diffuse bulging of disc at the level of C45 and C56 without showing significant spinal canal stenosis.Spinal cord signal intensity is normal.Thoracic MRIThere are multifocal bone marrow replacing lesions involving T7, T8, T12 and L1 vertebral bodies. In particular, the T7 and T8 vertebral bodies demonstrate various degree of compression fractures; about 50% for T7 and 30% for T8.The T8 vertebral compression fracture is associated with minimal retropulsion, however, there is no evidence of spinal canal stenosis, nor abnormal spinal cord signal intensity. There are multiple non vertebral abnormal enhancing lesions indicating metastatic lesion involving right mid to lower pleural spaces and lung parenchyme as well as right side paravertebral muscle at the level of L1.The cord signal is normal. The conus medullaris terminates at the level of T12-L1.
1. Multifocal metastatic lesions involving C7, T1, T7, T8, T12 and L1 vertebral levels.2. Vertebral compression fractures on T7 and T8.3. No spinal cord signal abnormality.4. Multifocal metastatic lesions involving left pleural space, left lung parenchyme and right paraspinal muscle (L1 level).
