Summary
Idiopathic hypertrophic cranial pachymeningitis, a rare dural thickening condition, can cause neurological deficits. Combined corticosteroid and immunosuppressive therapy effectively resolved symptoms in three patients.
Area of Science:
- Neurology
- Pathology
Background:
- Idiopathic hypertrophic cranial pachymeningitis is a rare chronic inflammatory condition causing dura mater thickening.
- This thickening can lead to significant neurological deficits, often presenting as cranial neuropathy and headache.
Purpose of the Study:
- To report the clinical features, neuroimaging, histopathology, and treatment outcomes of three patients diagnosed with idiopathic hypertrophic cranial pachymeningitis.
Main Methods:
- Case series reporting on three patients with idiopathic hypertrophic cranial pachymeningitis.
- Diagnostic methods included clinical assessment, brain MRI for dural thickening, and histopathological examination of dural tissue.
- Treatment involved a combination of corticosteroid and immunosuppressive drugs.
Main Results:
- All three patients exhibited prominent dural thickening on MRI and chronic inflammatory cell infiltration upon histopathological analysis.
- Clinical presentations included abducens nerve palsy, cranial nerve IX-XII lesions, and optic neuropathy, all associated with headaches.
- Combined therapy led to near-complete symptom resolution, with residual visual impairment in one case.
Conclusions:
- Idiopathic hypertrophic cranial pachymeningitis requires a multimodal diagnostic approach.
- Combined corticosteroid and immunosuppressive therapy demonstrates significant efficacy in managing this rare condition.

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...
01:29Increased 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...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
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...
01:24Bacterial 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,...
