Pineal cysts measuring 5 mm or larger in greatest dimension were found in 478/48,417 patients (1.0%). Follow up imaging was present in 151 patients for greater than 3 years. The authors conclude that follow-up imaging and neurosurgical evaluation are not mandatory for adults with asymptomatic pineal cysts.

The authors describe the patterns of arterial injury after chiropractic manipulation and their management in the modern endovascular era in 13 patients since 2007. Of particular note was the severity of the arterial injuries in the cohort. Not only were these lesions often lengthy, their neurological sequelae were frequently severe. Three patients were left permanently debilitated by stroke and 1 died, producing an adverse outcome rate of 31% (4 of 13 patients).

Very complete review of the anatomy and physiology of the intervertebral disc, including over 200 references. It is amazing to me that we still do not know the precise origin and nature of the cells within the intervertebral disc, or the fate of the notochord cells.
