Summary
Infective skull base lesions can cause lower cranial nerve palsies, particularly in elderly individuals. This study highlights that these conditions are not limited to immunocompromised or diabetic patients.
Area of Science:
- Neurology
- Otolaryngology
- Infectious Diseases
Background:
- Diseases of the temporal bone can lead to lower cranial nerve palsies.
- Bony erosion in this region often suggests a malignant process.
- Osteomyelitis and inflammatory masses are considered in immunocompromised or diabetic patients with otitis externa.
Observation:
- This study presents four cases of infective skull base lesions causing multiple lower cranial nerve palsies.
- The affected patients were elderly and did not have compromised immune systems or diabetes.
- These cases challenge the typical patient profile for such conditions.
Findings:
- Infective skull base lesions can manifest as lower cranial nerve palsies in elderly patients without typical risk factors.
- The findings indicate that osteomyelitis and inflammatory masses are not exclusive to immunocompromised or diabetic populations.
- This broadens the differential diagnosis for cranial nerve palsies in the elderly.
Implications:
- Clinicians should consider infective skull base lesions in the differential diagnosis of lower cranial nerve palsies, even in non-immunocompromised, non-diabetic elderly patients.
- Early recognition and appropriate management of these lesions are crucial to prevent further neurological deficits.
- This research expands the understanding of the epidemiology and presentation of infective skull base pathologies.

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,...
01:19Cranial Nerves: Overview and Anatomy
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...
01:22Cranial Nerves: Types Part II
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

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...
