Epidermoid cysts (ECs) account for 0.5% to 1% of all spinal tumors. They can be congenital or acquired. Acquired spinal ECs are extremely rare and are mostly caused by trauma, or secondary to iatrogenic procedure such as lumbar punctures or surgery for spina bifida. As far as we know, this is the first report of a spinal EC complicating surgery for a lumbar disc herniation. ⋯ Despite the extreme rarity of this event, we should be aware of the potential de novo development of epidermoid tumors in patients who undergo surgery for lumbar disc herniation. Concerns must be given to persistent low back pain and delayed neurologic symptoms in these patients.

Post-dural puncture headache (PDPH) has been the most common complication of diagnostic and therapeutic lumbar puncture (LP). The occurrence and clinical features of PDPH in relationship to different demographic, clinical, and paraclinical parameters and parameters related to LP were assessed. ⋯ The results of the present study are important for the prediction of the occurrence of PDPH and the differential diagnosis of headaches after LP.

Compensatory mechanisms for cervical kyphosis are unclear. Few alignment analyses have targeted ongoing cervical kyphosis and detailed the effects of compensatory alignment changes. ⋯ When CL decreased after ACCF, ΔO-C2 immediately compensated for the CL loss that could lead to failure to obtain horizontal gaze. If cSVA increased, Δcaudal adjacent angle and ΔT1 slope (extension below the kyphosis) compensated for the horizontal offset translation. The noncompensatory status (ΔcSVA and ΔT1 positive) may necessitate further correction surgery in which the caudal fused level is beyond T1.

Carotid cavernous aneurysm (CCA) rupture is rare. However, it can result in various complications such as carotid cavernous fistula (CCF), epistaxis, spontaneous thrombosis, and subarachnoid hemorrhage. ⋯ In patients with clinical manifestation of OCS with no history of any predisposing risk factors, diagnosis of ruptured cavernous sinus aneurysm and resulting direct CCF should be considered. In such cases, emergent imaging along with early endovascular intervention can resolve OCS and prevent permanent ocular injury and vision loss.

With an aging population and advances in neuroanesthesia and critical care, an increasing subgroup of elderly patients have been undergoing neurosurgery. Of particular relevance is the cohort aged >80 years. The aim of the present study was to investigate the 30-day mortality and survival in this cohort after emergency and elective neurosurgery. ⋯ The current model for accepting elderly patients has been associated with good overall outcomes. The elderly should not be refused neurosurgery on the basis of their age alone. However, we applied fairly strict criteria, especially for those with subarachnoid hemorrhage, which should be factored into our results.
