Secondary brain injuries, such as delayed cerebral infarction (DCI), are the leading causes of disability after subarachnoid hemorrhage (SAH). Detecting DCI may be challenging, especially for patients presenting an altered level of consciousness. ⋯ Multiple secondary complications (DCI, seizures, hydrocephalus) may occur after SAH but are clinically difficult to diagnose. A multimodal evaluation (transcranial Doppler, CT or magnetic resonance imaging, electroencephalography) is useful in order to detect and treat late complications.

Colloid cysts (CCs) are rare cystic lesions derived from the endoderm of the central nervous system. Although they appear most commonly in the anterior roof of the third ventricle, there are only a few reports of CCs located in the suprasellar region. Although CCs are considered to be slow-growing benign tumors, their developmental process remains unclear. ⋯ This case suggests that CC may be one of several possible diagnoses in patients who present with suprasellar cystic lesions. Even if CCs in the suprasellar region remain asymptomatic, radiological follow-up is required due to possible progressive enlargement of the cyst.

This study aimed to compare radiographic outcomes of adult spinal deformity (ASD) surgery with or without 2-level prophylactic vertebroplasty (PVP) at the uppermost instrumented vertebra (UIV) and the vertebra 1 level proximal to the UIV. ⋯ PVP at UIV and vertebra 1 level proximal to the UIV cannot prevent PJK, PJF, and PJFX; however, it plays a positive role by delaying their progression. Furthermore, PVP tends to lower the reoperation rate after PJFX in ASD surgery.

We hypothesized that women undergoing scoliosis surgery who became pregnant would go to full term, have uncomplicated pregnancies, and similar patient-reported outcome measures than non-pregnant patients and healthy controls. ⋯ Women with a history of spinal fusion for AIS fused to L3 or L4 reported a higher incidence of low BP, and CSs are more frequently required. This risk increased to 55% when spinal fusion to L4 was performed. The quality of life and sexual function were at the same level in women after scoliosis surgery than in healthy controls.

Whether the risk of rupture of a cerebral arteriovenous malformation (AVM) increases during pregnancy remains controversial. Moreover, it is unclear whether the number of pregnancies correlates with AVM rupture risk. We report a case of ruptured AVM during the fifth pregnancy. ⋯ This report suggests that the risk of AVM rupture persists even after multiple deliveries. Intracranial hemorrhage should be suspected in pregnant patients who underwent multiple deliveries, and a rapid diagnosis and appropriate treatment are necessary.
