Spinal cord compression Anatomy Extends from foramen magnum to L1 – L2 Below the termination of the cord it contains the lumber cistern, an enlargement of the subarachonoid space that surrounds the cauda equina. SAS terminates inferiorly at S2 – S3.
Clinical Presentation Pain (90%-95%),usually precedes all other symptoms by several weeks to months Weakness is rarely the first symptom (2%)but is fairly common at diagnosis (75%). Sensory loss (50%) Autonomic dysfunction associated with unfavorable prognosis and late (50%) Once neurologic deficits develop, impairment progresses rapidly.
Diagnostic imaging (MRI (Gold standard if neurological symptoms CT Conventional Myelography XRay
Treatment Steroid to be started immediately and then taper as tolerated Surgery as a first line if 1- diagnosis unknown or doubtful for malignancy 2-instability of spine or bony compression of the cord 3- previous radiation of the site of compression 4- progression during radiation 5- contra indication of radiation or radiation resistant tumor.
CONT.. Radiation Post op Alone if multiple levels of compression or poor performance status patient.
Superior Vena Cava Syndrome Superior Vena Cava Syndrome is a medical emergency occasionally seen in patients with malignant tumor that requires immediate action Causes 1- bronchogenic carcenoma 80 % 2- Malignant lymphoma % 3- Benign 2-3%
Diagnosis Biopsy CT
1 = carina 2 = left main bronchus 3 = right main bronchus 4 = right upper lobe bronchus 5 = descending aorta 6 = superior vena cava
Treatment 1- Radiation 2- Chemotherapy in case of Small Cell Lung Cancer Or Lymphoma 3- Steroids 4- ? Diuretics
Bone Metastases Common cause of severe cancer pain Good pain control may improve OS Sites of mets : Spine (Lumber > Thoracic) > Pelvis > Ribs >femur >Skull Primary ( breast, Prostate, Thyroid, Kidney. Lung)
Workup Bone scan is the primary imaging modality Plain films looking for fracture MRI for Spinal cord Biopsy if unknown primary
Treatment 1- Supportive including pain control 2-Surgery incase of fracture or impending fracture 3- Radiation
