Insights

Diagnosing abusive head trauma (AHT) is challenging due to unclear criteria. Benign external hydrocephalus (BEH) in infants can be misdiagnosed as AHT, highlighting the need for expert evaluation.

Area of Science:

  • Pediatrics
  • Neurology
  • Forensic Medicine

Background:

  • Diagnostic criteria for abusive head trauma (AHT), also known as shaken baby syndrome, are not well-defined.
  • This ambiguity can lead to misdiagnoses based on insufficient evidence.

Purpose of the Study:

  • To investigate the potential misdiagnosis of benign external hydrocephalus (BEH) as abusive head trauma (AHT).
  • To propose measures to prevent diagnostic errors in infant head trauma cases.

Main Methods:

  • A study collected data on 28 infants suspected of violent shaking, with caregivers under investigation.
  • Clinical and radiological findings, including head circumference, symptoms, and neuroimaging, were analyzed.

Main Results:

  • Eighty-one percent of symptomatic infants had head circumference at or above the 90th percentile.
  • Macrocephaly and seizures were common symptoms; 65% had bilateral retinal hemorrhages.
  • All infants showed neuroimaging findings consistent with chronic subdural hematomas/hygromas and benign external hydrocephalus (BEH).

Conclusions:

  • Benign external hydrocephalus (BEH) with subdural hematomas/hygromas can be misdiagnosed as abusive head trauma (AHT).
  • Medical experts must be trained in recognizing BEH features.
  • Inclusion of neuro-pediatric clinicians and access to head circumference history are crucial for accurate diagnosis.

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

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,...

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...
Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
Cerebral Edema l: Introduction01:19

Cerebral Edema l: Introduction

Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
