Nonfunctional pituitary neuroendocrine tumors (PitNETs) exhibit wide variability in growth pattern based on subtype. Silent corticotroph adenomas (SCAs) demonstrate aggressive growth compared with other nonfunctional pituitary adenomas (NFPAs), especially into the cavernous sinus. In this study, we sought to characterize other growth patterns of SCAs compared with NFPAs. ⋯ Silent corticotroph PitNETs demonstrate predilection for invasion of bony structures, with higher rates of growing through the sellar floor into the sphenoid sinus, growing posteroinferiorly into the clivus and laterally into the cavernous sinuses. Other nonfunctional PitNETs tended to follow the path of least resistance, growing superiorly into the suprasellar space. These differences in growth patterns may account for some of the clinical challenges of treating silent corticotroph PitNETs.

Surgical timing after rupture of brain arteriovenous malformations (AVMs) is controversial. There is scarce literature on AVM surgical outcomes from developing countries. This study aims to determine if there is a difference between early and delayed surgical resection for patients with ruptured brain AVMs. ⋯ In this case series of 31 patients from a developing country, there were no differences in clinical outcomes at the final follow-up between acute and delayed surgical interventions for ruptured AVMs. The most important factor associated with the final outcomes was the initial Glasgow Coma Scale.

Bilateral orbital metastases are extremely rare, and no previous literature has reported bilateral multiple orbital metastases treated with stereotactic radiosurgery (SRS). We present the impressive images of a patient with history of metastatic leiomyosarcoma with newly diagnosed bilateral multiple orbital metastases. The pre-SRS magnetic resonance imaging (MRI) showed 1 right and 2 left orbital metastatic lesions. ⋯ The presenting symptoms were all improved after the treatment with no adverse effects from the SRS. Our interesting images show the presence of multiple lesions in the orbital spaces with excellent treatment response post SRS. This is the first report of a patient who has bilateral and multiple orbital metastases that were successfully treated with standalone SRS.

Incidence, clinical course, and fatality of spontaneous subarachnoid hemorrhage (SAH) are evolving, with prevalence of risk factors diminishing, implementation of early detection programs and strategies for priority aneurysm exclusion, technical refinement with less invasive procedures, and improvements in neurocritical care. Modern epidemiological and prognostic data are lacking, especially in southern European and Mediterranean populations. ⋯ Even when most patients received timely aneurysm treatment, case fatality rates were considerably high. Data provided by the HSACat project may have public health effects and be used to guide prevention programs and screening strategies.

Craniocerebral trauma is one of the main causes of death and disability worldwide. Decompressive craniectomy is a common emergency measure in the treatment of craniocerebral trauma, aimed at relieving intracranial pressure. However, cranial bone reconstruction (CP) following this surgery is crucial for the patient's long-term recovery. Despite this, research on complications and prognostic factors after ultra-early cranioplasty remains limited. Therefore, this study aims to explore the complications of ultra-early cranioplasty with titanium mesh and its impact on prognosis. ⋯ Ultra-early CP can promote the recovery of neurological function, reduce the disturbance of consciousness, improve daily living ability, and improve cognitive function in patients with craniocerebral trauma, but there is a high risk of postoperative complications. In addition, age and postoperative NIHSS score are related factors affecting the poor prognosis of ultra-early CP patients.
