Insights

Moyamoya disease, a rare condition causing blocked arteries, can lead to unusual brain hemorrhages. This case highlights a rare splenium of the corpus callosum hemorrhage in a moyamoya patient.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Neuroimaging

Background:

  • Moyamoya disease is a rare, progressive cerebrovascular disorder characterized by stenosis or occlusion of the terminal internal carotid arteries and proximal anterior and middle cerebral arteries.
  • Hemorrhage, particularly in atypical locations, is an uncommon but serious complication of moyamoya disease.

Observation:

  • A 53-year-old woman presented with a one-week history of unsteadiness and a tendency to fall forward.
  • Cerebral angiography confirmed the diagnosis of moyamoya disease.
  • Head computed tomography (CT) scan revealed an atypical hemorrhage in the splenium of the corpus callosum.

Findings:

  • The patient's symptoms were attributed to a rare manifestation of moyamoya disease: hemorrhage in the splenium of the corpus callosum.
  • The imaging findings underscore the diverse clinical presentations of moyamoya disease.

Implications:

  • This case expands the understanding of potential hemorrhagic complications in moyamoya disease.
  • Highlights the importance of considering moyamoya disease in patients presenting with neurological symptoms and atypical intracranial hemorrhages.
  • Emphasizes the role of advanced neuroimaging in diagnosing rare cerebrovascular conditions and their complications.

Antipsychotic Drugs: Typical and Atypical Agents01:21

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...

Location and Orientation of the Heart01:13

Location and Orientation of the Heart

The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Perceiving Loudness, Pitch, and Location01:21

Perceiving Loudness, Pitch, and Location

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

Selected Data About Geographic Locations

Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
