Hydatid cysts (HCs) are caused by parasites, the larvae of Echinococcus granulosus. They usually affect the liver and lung, but primary brain involvement is rarely seen. HCs may cause a mass effect in the brain. For this reason, surgical excision must be performed. Complications may rarely occur after surgery. Recognition of complications is of vital importance. ⋯ Surgical resection should be applied carefully in the treatment of cerebral cysts. Complications may occur later in patients who do not develop complications at the time of operation. For this reason, follow-up of the patients should definitely be done by magnetic resonance imaging.

Endoscopic Transnasal Transclival Approach to a Pontine Cavernoma with Associated Developmental Venous Anomaly.
Brainstem cavernous malformations represent around 8%-22% of all intracranial cavernous malformations but exhibit a higher annual incidence of hemorrhage (2%-3%) compared with other cavernous angiomas and tend to be more symptomatic given their proximity to critical nuclei and fiber tracts. Recently, endoscopic endonasal techniques have been used for the removal of ventral skull base lesions, with significant improvement in operative morbidity and mortality compared with open approaches. Here we demonstrate the utility and feasibility of the endoscopic transclival approach for ventrally located pontine cavernomas in carefully selected patients. ⋯ This approach provided direct visualization of the lesion and the associated DVA allowing for a gross total resection without injury to the DVA. The transclival approach may be considered as an alternative to open lateral and dorsolateral neurosurgical approaches for ventral brainstem cavernomas in carefully selected patients.

Severe complications after reperfusion therapy for acute major vessel occlusion are not well described. We present an extremely rare case of a patient with rapid malignant brain swelling subacutely after acute ischemic stroke. ⋯ This case has similarities to both second-impact syndrome after head trauma and perfusion breakthrough phenomenon. Initial ischemic damage following reperfusion therapy and damage secondary to sepsis and subarachnoid hemorrhage may have led to rapid malignant brain swelling in this patient. Careful management is important for patients receiving reperfusion therapy.

To assess association between champagne bottle neck sign (CBNS) in carotid artery and intracranial hemorrhage in patients with moyamoya disease (MMD). ⋯ CBNS is significantly associated with intracranial hemorrhage in the ipsilateral hemisphere in patients with MMD, particularly intracranial hemorrhage in posterior territories.

Patients with an aneurysmal subarachnoid hemorrhage (aSAH) and World Federation of Neurosurgical Societies (WFNS) grade I on admission are generally considered to have a good clinical outcome. ⋯ Despite their neurologically optimal clinical condition on admission, 1 in 5 patients with WFNS grade I aSAH has an unfavorable clinical outcome or is dead at 6-month follow-up. Additional multivariable analysis in larger patient cohorts is necessary to identify the extent to which preventable complications contribute to unfavorable outcomes in these patients.
