Insights

A pediatric giant aneurysm in the internal carotid artery caused headaches and vision loss. Endovascular obliteration led to successful aneurysm regression, confirmed by MRI.

Area of Science:

  • Pediatric Neurology
  • Vascular Neurosurgery
  • Endovascular Therapy

Background:

  • Giant aneurysms are rare in children.
  • Supraclinoid internal carotid artery aneurysms can present with mass effect symptoms.
  • Aneurysms may mimic other suprasellar lesions like craniopharyngioma.

Purpose of the Study:

  • To report a case of a partially-thrombosed giant lobulated aneurysm in a pediatric patient.
  • To discuss the diagnostic challenges and endovascular management of such cases.
  • To highlight the successful outcome of endovascular obliteration and aneurysm regression.

Main Methods:

  • Case presentation of a 2-year-old boy with progressive headache and visual loss.
  • Diagnostic imaging including CT, revealing a suprasellar mass.
  • Successful endovascular obliteration of the aneurysm.

Main Results:

  • The lesion was identified as a partially-thrombosed giant lobulated aneurysm.
  • Endovascular obliteration was technically successful.
  • Follow-up MRI confirmed regression of the aneurysm.

Conclusions:

  • Giant aneurysms in the supraclinoid internal carotid artery are a rare but significant cause of neurological deficits in children.
  • Endovascular treatment is a viable and effective option for managing pediatric giant aneurysms.
  • Prompt diagnosis and intervention can lead to favorable outcomes and regression of the aneurysm.

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: 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,...
The Arch of Aorta01:10

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

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...

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
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...
