Summary
Rarely, vacuum disc phenomenon can cause nerve compression. This study details two cases where gas from the disc formed an epidural cyst, leading to lumbosacral radiculopathy.
Area of Science:
- Neurosurgery
- Radiology
- Spinal Imaging
Background:
- Vacuum disc phenomenon involves gas accumulation within the intervertebral disc space.
- While typically asymptomatic, rare instances can lead to spinal canal gas displacement.
- Epidural gas can compress neural structures, causing symptoms like radiculopathy.
Purpose of the Study:
- To describe two cases of symptomatic epidural gas-containing cysts.
- To investigate the origin of these cysts from intervertebral vacuum phenomenon.
- To analyze the mechanism of nerve root compression by these cysts.
Main Methods:
- Case report of two patients with lumbosacral radiculopathy.
- Radiographic evaluation including imaging of the lumbar spine.
- Analysis of gas collection in the epidural space and its relation to the intervertebral disc.
Main Results:
- Both patients presented with symptomatic epidural gas-containing cysts.
- Radiographic studies confirmed intervertebral vacuum phenomenon and lumbar epidural gas accumulation.
- Gas-containing cysts compressed the dural sac and nerve roots, causing radiculopathy.
Conclusions:
- Epidural gas-containing cysts originating from vacuum disc phenomenon can cause nerve root compression.
- Consideration of gas-containing cysts is important in cases of epidural gas and nerve root compression.
- The findings highlight a rare but significant cause of lumbosacral radiculopathy.

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

2.1K
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.
