Abstract:

Atypical meningiomas represent a minority of intracranial meningiomas yet carry more aggressive biological behavior and higher recurrence rates, making preoperative differentiation essential for optimal management. We report a 56-year-old female presenting with progressive headaches, drowsiness, and vomiting, with no focal neurological deficits. Brain Magnetic Resonance Imaging (MRI) revealed a dural-based lesion at the posterior falx with cystic components, irregular margins, heterogeneous enhancement, disproportionate peritumoral edema, all suggesting atypicality. Subtotal resection followed by histopathological analysis confirmed a atypical meningioma. This case underscores the pivotal role of comprehensive MRI-including conventional sequences and advanced techniques-in identifying features of atypical meningioma even without definitive brain invasion, thereby guiding appropriate surgical planning and consideration of adjuvant therapy.

Interslice Magnetization Transfer Ratio Imaging for Meningioma Detection

Begin with a patient with meningioma, or a brain tumor, positioned in an MRI scanner for non-invasive brain imaging.Adjust the scanner to obtain structural images of individual slices of the brain.Enhance the contrast to improve tissue differentiation.Use interslice magnetization transfer ratio imaging on brain slices using radiofrequency pulses slightly offset from the MRI signal.The pulses deliver energy to the proton pool in macromolecules and bound water molecules.This energy transfers to...

Examining Gesture Production in the Presence of Communication Challenges

Examining Gesture Production in the Presence of Communication Challenges

Here, we present a protocol that manipulates interlocutor visibility to examine its impact on gesture production in interpersonal communication. This protocol is flexible to tasks implemented, gestures examined, and communication modality. It is ideal for populations with communication challenges, such as second language learners and individuals with autism spectrum...

Antipsychotic Drugs: Typical and Atypical Agents

Antipsychotic Drugs: Typical and Atypical Agents

Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...

Acetylcholine Re-Challenge After Intracoronary Nitroglycerine Administration

This protocol presents the acetylcholine rechallenge after nitroglycerine as an add-on procedure to spasm provocation testing. The purpose of this technique is to unmask co-existing microvascular spasm in patients with epicardial spasm and to assess the protective efficacy of nitroglycerine on a per-patient level to guide medical...
