</div></div><div class="section-body" id="section-1"><p>A spinal cord abscess is caused by an infection inside the spine. An abscess of the spinal cord itself is very rare. A spinal abscess usually occurs as a complication of an <a test="test" href="./001416.htm">epidural abscess</a>.</p><p>Pus forms as a collection of:</p><ul><li>White blood cells</li><li>Fluid</li><li>Live and dead bacteria or other microorganisms</li><li>Destroyed tissue cells </li></ul><p>The pus is commonly covered by a lining or membrane that forms around the edges. The pus collection causes pressure on the spinal cord.</p><p>The infection is usually due to bacteria. Often it is caused by a staphylococcus infection that spreads through the spine. It may be caused by <a test="test" href="./000077.htm">tuberculosis</a> in some areas of the world, but this is not as common today as it was in the past. In rare cases, the infection may be due to a fungus.</p><p>The following increase your risk for a spinal cord abscess:</p><ul><li>Back injuries or trauma, including minor ones</li><li><a test="test" href="./001474.htm">Boils</a> on the skin, especially on the back or scalp (rare)</li><li>Complication of <a test="test" href="./003428.htm">lumbar puncture</a> or back surgery</li><li>Spread of any infection through the bloodstream from another part of the body (<a test="test" href="./000666.htm">bacteremia</a>)</li><li>Injecting drugs </li></ul><p>The infection often begins in the bone (<a test="test" href="./000437.htm">osteomyelitis</a>). The bone infection may cause an epidural abscess to form. This abscess gets larger and presses on the spinal cord. The infection can spread to the cord itself.</p><p>A spinal cord abscess is rare.
