Introduction Intraspinal gas is a common clinical finding, but an epidural gas pseudocyst in association with lateral disc herniation compressing a nerve root is an exceptional observation. Case Report A 49-year-old man was admitted to our department presenting with sciatica. The neurological examination demonstrated moderate lumbar pain without neurological deficit. A lumbosacral computed tomography showed the presence of degenerated disc herniation and epidural gas collection. Discussion The pathological association between the cyst and the hernia is probably due to the migration of gas pumped from the intervertebral space through a breaking point or lower in the annulus fibrosis, involving its contiguity with the herniated disc. Conclusion An association between a disc herniation and a gas pseudocyst can be a cause of sciatica.

Clinical Cases

The authors performed retrospective analysis of 180 clinical cases of surgical treatment of lumbar herniated discs in patients who underwent endoscopic transforaminal microdiscectomy. This technique allows minimally invasive insertion of the endoscope into the spinal canal under local anaesthesia to decompress the nerve root by removing hernial protrusion under visual control. However, this technique is not universal and cannot be applied to all patients. Considerable practical experience has shown that the surgeon may encounter certain technical difficulties in cases of cranial or caudal sequester migration and in some cases when the access at L5–S1 level is complicated due to the high standing of the iliac crest. However, if there are correct indications, this technique allows to solve the problem of radicular compression syndrome in a short time.

Methane Budget

Based on data on the spatial distribution and fluxes of streaming (bubbling) methane within the Black Sea, the rate of dissolved methane inflow to Black Sea deep waters was assessed. Calculations showed that gas bubble streams annually replenish the methane budget in the Black Sea by 1.2 109 m3, or 0.9 Tg, which is considerably less than determined by known biogeochemical estimates of components of methane balance in the Black Sea.
