Background: We present a rare case of a ruptured neoplastic aneurysms (NCA) caused by metastatic spread of triple-negative breast cancer (TNBC) in a female patient in her 60s. The patient had a medical history of TNBC and presented to the emergency department after experiencing 3 days of persistent headache.

Background: Reliable prediction models of intracerebral hemorrhage (ICH) outcomes are needed for decision-making of the treatment. Statistically making such prediction models needs a large number of samples and time-consuming statistical analysis. Deep learning (DL), one of the artificial intelligence, is attractive, but there were no reports on DL-based functional outcome prediction models for ICH outcomes after surgery. We herein made a functional outcome prediction model using DLframework, Prediction One (Sony Network Communications Inc., Tokyo, Japan), and compared it to original ICH score, ICH Grading Scale, and FUNC score.

Background: Although associated with controversy, decompressive craniotomy (DC) for malignant middle cerebral artery infarction (MMCAI) is an unequivocally lifesaving intervention. DC for MMCAI is rarely performed in lower- to middle-income countries.

Background: Tumefactive demyelinating lesions (TDLs) share similar clinical features and MRI characteristics with high-grade glioma (HGG). This study develops an approach to navigating this diagnostic dilemma, with significant treatment implications as the management of both entities is drastically different.

Background: Primary central nervous system (CNS) melanoma is a rare lesion derived from neural crest precursors. While its management is analogous to metastatic spinal melanoma, the literature does not describe this entity clearly in pregnant patients and the unique implications it presents. Here, we describe the case of a pregnant patient who presented with primary CNS melanoma of the cervical spine.

Background: Cerebral venous thrombosis (CVT) is a rare cause of stroke that preferentially affects reproductive aged females and patients with hereditary or acquired thrombotic risk factors. The superior sagittal sinus and transverse sinus are the two most common sites for thrombus formation.
