Insights

Accidental severe head trauma in neonates can cause retinal hemorrhages (RHs) and peripapillary intrascleral hemorrhages. These findings, previously thought unique to abusive head trauma, highlight the need for careful differential diagnosis.

Area of Science:

  • Ophthalmology
  • Pediatric Pathology
  • Forensic Medicine

Background:

  • Retinal hemorrhages (RHs) are often investigated in cases of suspected child abuse.
  • Peripapillary intrascleral hemorrhages (PIH) have been considered pathognomonic for abusive head trauma (AHT).
  • Current guidelines suggest avoiding postmortem eye removal in cases of clear accidental death.

Observation:

  • Two neonates experienced severe accidental in utero head injuries.
  • Autopsies revealed extensive RHs, optic nerve sheath hemorrhages, and PIH in both neonates.
  • Neither infant had a documented clinical fundal examination prior to death.

Findings:

  • The presence of RHs and PIH in neonates with accidental head trauma challenges their exclusive association with AHT.
  • Accidental severe head injuries, even in utero, can mimic findings typically attributed to abuse.
  • This underscores the importance of considering non-abusive etiologies for these ocular findings.

Implications:

  • Findings necessitate a broader differential diagnosis for RHs and PIH in neonates.
  • Rethinking diagnostic criteria for AHT may be required.
  • Careful clinical evaluation and consideration of accidental trauma are crucial in interpreting these pediatric autopsy findings.

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...

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...

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...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

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...
Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
