Traumatic Brain Injury l: Introduction01:28

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
Prosopagnosia01:24

Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
Transient Ischemic Attack l: Introduction01:26

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
Increased Intracranial Pressure l: Introduction01:14

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

Summary
This summary is machine-generated.

Post-traumatic cortical defects are asymptomatic bone lesions in children, typically occurring in the distal radius after fractures. These defects resolve spontaneously, requiring no treatment.

Area of Science:

  • Pediatric Orthopedics
  • Pediatric Radiology
  • Pediatric Bone Pathology

Background:

  • Post-traumatic cortical defects are rare, asymptomatic bone lesions observed in children following greenstick or torus fractures.
  • These defects commonly affect the distal radius and appear approximately three months post-injury, located near the fracture site.

Observation:

  • The pathogenesis is thought to involve intramedullary fat and blood accumulation under intact periosteum.
  • Diagnosis relies on computed tomography (CT) and magnetic resonance (MR) imaging.
  • This case report details a defect following distal radius epiphysiolysis, adding to the limited 25 reported cases.

Findings:

  • The lesion is asymptomatic and requires no intervention.
  • Spontaneous resolution is the typical outcome for these defects.
  • Imaging characteristics on CT and MR are crucial for diagnosis.

Implications:

  • Understanding post-traumatic cortical defects aids in accurate diagnosis and avoids unnecessary interventions in pediatric patients.
  • Further research into the exact pathogenesis may elucidate underlying mechanisms of bone healing and remodeling.
  • This case expands the literature on this rare entity, particularly its occurrence after epiphysiolysis.
