Insights

Spinal ultrasound effectively detects spinal subdural hematoma in infants with non-accidental trauma. This imaging technique is a valuable, non-invasive tool for diagnosing abuse in children.

Area of Science:

  • Pediatric Radiology
  • Neuroradiology
  • Emergency Medicine

Background:

  • Non-accidental trauma (NAT) in infants can lead to serious injuries, including subdural hematomas.
  • Accurate and timely diagnosis of NAT is crucial for intervention and preventing further harm.
  • Spinal subdural hematoma (SSH) is a potential indicator of NAT, but its detection can be challenging.

Purpose of the Study:

  • To evaluate the efficacy of spinal ultrasound in identifying spinal subdural hematomas in infants diagnosed with non-accidental trauma.
  • To determine if spinal ultrasound is a suitable imaging modality for detecting SSH in this vulnerable population.

Main Methods:

  • A case series involving six infants with suspected non-accidental trauma who underwent spinal ultrasound, CT, and/or MRI.
  • Twelve healthy infants undergoing spinal ultrasound for other reasons served as controls.
  • Radiological examinations included ultrasound, CT/MRI, and skeletal radiography.

Main Results:

  • All six infants with NAT presented with cranial subdural hematomas, confirmed by ultrasound and other imaging modalities.
  • Spinal ultrasound successfully identified spinal subdural hematomas in all six NAT patients, characterized by echogenic effusions.
  • The detected spinal subdural hematomas varied in size and extent, from the cervical spine to the cauda equina, and were asymptomatic.
  • Anatomic landmarks confirmed the subdural location of the hematomas.
  • No osseous lesions were identified on spinal X-rays, and controls did not exhibit spinal subdural hematomas.

Conclusions:

  • Spinal subdural hematoma is a significant indicator of sustained non-accidental trauma in infants.
  • Spinal ultrasound provides a rapid, non-invasive, and effective method for detecting spinal subdural hematomas without requiring sedation or anesthesia.
  • Spinal ultrasound should be incorporated into the standard imaging workup for infants with suspected non-accidental trauma.

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...
Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

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...
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...
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,...
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...
