Dolichoectasia is a rare disorder of the cerebral vasculature consisting of vascular elongation, widening, and tortuosity, usually involving the vertebral and basilar arteries. Its neurological symptoms and signs are highly variable. ⋯ Vertebrobasilar dolichoectasia can cause multiple clinical manifestations, with hydrocephalus being less common. In addition, having dolichoectasia of both posterior and anterior circulation is extremely rare.

Pneumocephalus is a complication of head injury in 3.9-9.7% of the cases, it also appears after supratentorial craniotomy in 100% of cases. The accumulation of intracranial air can be acute (<72 hours) or delayed (≥72 hours). When intracranial air causes intracranial hypertension and has a mass-effect with neurological deterioration, it is called tension pneumocephalus. ⋯ Tension pneumocephalus is a life-threatening neurosurgical emergency case, which needs to undergo immediate surgical or conservative treatment.

Vertebral artery injuries during cervical spine surgery are rare, but potentially fatal. When performing cervical spine surgery, it is imperative that the surgeon has a systematic approach for avoiding, and if necessary, dealing with a vertebral artery injury. ⋯ Prior to performing cervical spine surgery, one must understand the four A's of vertebral artery injuries: Anatomy, Assessment, Avoidance, and Action.

Multiple type of spinal injections, whether epidural/translaminar or transforaminal, facet injections, are offered to patients with/without surgical spinal lesions by pain management specialists (radiologists, physiatrists, and anesthesiologists). Although not approved by the Food and Drug Administration (FDA), injections are being performed with an increased frequency (160%), are typically short-acting and ineffective over the longer-term, while exposing patients to major risks/complications. ⋯ Although the benefits for epidural steroid injections may include transient pain relief for those with/without surgical disease, the multitude of risks attributed to these injections outweighs the benefits.

Hepatic cerebrospinal fluid pseudocyst: A rare complication of ventriculoperitoneal shunt.
Ventriculoperitoneal (VP) shunts are among the most frequently performed operations in the management of hydrocephalus. Hepatic cerebrospinal fluid (CSF) pseudocyst is a rare but important complication in patients with a VP shunt insertion. In addition to presenting our own case, we performed a PubMed search to comprehensively illustrate the predisposing factors, clinical picture, diagnostic methods, and surgical treatment. This article represents an update for this condition. ⋯ Hepatic CSF pseudocyst is a rare complication of a VP shunt. Once the diagnosis is verified and if the CSF is sterile, just simply remove the peritoneal catheter and reposition a new one in the abdomen. We believe that it is not necessary to remove or aspirate the hepatic intraaxial pseudocyst, because of the risk of bleeding. In case of CSF infection, the VP shunt can be removed and/or an external derivation can be made, and after treatment with antibiotics, a new VP shunt is placed in the opposite side of the peritoneum.
