Summary
A young man experienced severe headache and collapse due to atypical giant cell arteritis (GCA) affecting cerebral arteries. This rare, disseminated GCA case highlights unusual arterial inflammation and cerebral infarction in a young patient.
Area of Science:
- Neurology
- Pathology
- Rheumatology
Background:
- Giant cell arteritis (GCA) typically affects older individuals and commonly involves cranial arteries.
- Disseminated GCA, particularly in young patients and involving extensive cerebral arteries, is exceedingly rare.
Observation:
- A 24-year-old male presented with severe headache, collapse, and CT findings of cerebral artery filling defects.
- Post-mortem examination revealed arteritis with giant cells, lymphocytes, and histiocytes in cerebral arteries, carotid siphons, and a renal artery.
- Extensive workup excluded systemic and infectious etiologies.
Findings:
- The case was diagnosed as atypical, disseminated GCA involving anterior, middle, and posterior cerebral arteries, leading to cerebral infarction.
- This presentation is distinct from classic GCA (temporal arteritis) and represents a previously unreported pattern of disseminated GCA.
Implications:
- This case expands the known spectrum of GCA, demonstrating its potential to affect young individuals and present with widespread arterial involvement.
- It underscores the importance of considering atypical GCA in the differential diagnosis of unexplained cerebral infarction, even in younger populations.
- Further research may be warranted to understand the pathogenesis and risk factors associated with this rare variant of GCA.

01:20Disorders of the Male Reproductive System
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.

01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:14Increased 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...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
01:26Brain 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,...
