Study Notes
Meningitis
- Meningitis is an inflammation of the meninges, the membranes that surround the brain and spinal cord.
- The meninges consist of three layers: the dura mater, arachnoid mater, and pia mater.
- The dura mater is the outermost layer and is tough.
- The arachnoid mater is a delicate membrane that lies beneath the dura mater.
- The pia mater is the innermost layer and is closely attached to the brain and spinal cord.
- The space between the arachnoid mater and the pia mater is called the subarachnoid space, and this space contains cerebrospinal fluid (CSF).
Encephalitis
- Encephalitis is an inflammation of the brain parenchyma.
- Encephalitis is a generalized inflammation of the brain tissue.
Leptomeninges
- The arachnoid and pia mater are collectively known as the leptomeninges.
- Leptomeninges are delicate membranes.
- Leptomeninges are inflamed in most cases of meningitis.
Pachymeninges
- The dura mater is often referred to as pachymeninges.
Cerebritis
- Cerebritis is a localized inflammation of the brain parenchyma.
- It is a localized uncapsulated inflammation of brain parenchyma.
Cerebral Abscess
- A cerebral abscess is a localized collection of pus in the brain.
- Cerebral abscesses are typically caused by bacterial infections.
- Cerebral abscesses are encapsulated collections of pus in the brain.
- Cerebritis can evolve into a cerebral abscess if the inflammation is not adequately treated, and capsule formation occurs.
Key Differences Summary
-
Meningitis vs. Encephalitis:
- Meningitis is inflammation of the meninges, while encephalitis is inflammation of the brain parenchyma.
- Meningitis is a generalized inflammation of leptomeninges, encephalitis is a generalized inflammation of the brain tissue.
-
Cerebritis vs. Cerebral Abscess:
- Cerebritis is a localized uncapsulated brain parenchyma inflammation, while a cerebral abscess is a localized, encapsulated collection of pus in the brain.
-
Leptomeninges vs. Pachymeninges:
- Leptomeninges are the delicate inner two layers of membranes: the arachnoid and pia mater, while the dura, the outermost layer, is called the pachymeninges.
