A 72-year-old man with a history of metastatic prostate cancer is brought to the emergency department with a 2-day history of progressively worsening lower back pain, bilateral leg weakness, and new-onset urinary incontinence. Neurologic examination reveals decreased sensation to pinprick below the umbilicus, 2/5 motor strength in both lower extremities, and hyperreflexia in the knees and ankles. Anal sphincter tone is decreased. You suspect malignant epidural spinal cord compression. Arrange the following management steps in the most appropriate chronological order.
- 1Administer high-dose intravenous dexamethasone.
- 2Obtain an urgent magnetic resonance imaging (MRI) scan of the entire spine.
- 3Consult neurosurgery or radiation oncology.
- 4Initiate definitive surgical decompression or palliative radiation therapy.
Cevap
The correct sequence is to first administer intravenous dexamethasone, then obtain an MRI of the spine, followed by consulting neurosurgery or radiation oncology, and finally initiating definitive surgical decompression or radiation therapy.
Malignant epidural spinal cord compression (MESCC) is an oncologic emergency. The first and most critical step in management is the immediate administration of high-dose intravenous glucocorticoids (e.g., dexamethasone) based purely on clinical suspicion. This reduces peritumoral edema, relieves pressure on the spinal cord, and preserves neurologic function. Once steroids are given, an urgent MRI of the entire spine is obtained to confirm the diagnosis and delineate the extent of the disease. Following imaging, surgical or radiation oncology specialists are consulted to determine the best definitive treatment, which is then initiated.

Malignant epidural spinal cord compression is an oncologic emergency requiring empiric high-dose glucocorticoids immediately upon clinical suspicion, prior to any confirmatory imaging.
