Summary
This case study highlights a rare instance of hypertrophic pachymeningitis (HP) in an adolescent, presenting with hypoglossal nerve palsy. Surgical intervention, initially suspected for meningioma, led to a diagnosis of HP with subsequent MRI regression.
Area of Science:
- Neurology
- Neurosurgery
- Pathology
Background:
- Hypertrophic pachymeningitis (HP) is a rare dural thickening, often challenging to diagnose, particularly in pediatric cases.
- Distinguishing HP from meningioma can be difficult due to similar MRI findings, complicating diagnosis without histological confirmation.
Observation:
- An 18-year-old male presented with hypoglossal nerve palsy and dysphagia following a middle ear infection.
- Initial surgical exploration, prompted by suspicion of meningioma, revealed no tumor, leading to a diagnosis of HP.
Findings:
- Post-surgical follow-up MRI demonstrated significant regression of the pathological dural changes.
- The patient experienced an uneventful postoperative recovery.
Implications:
- This case underscores the importance of considering HP in the differential diagnosis of cranial nerve palsies, even with initial suspicion of tumors.
- Successful management of HP may involve surgical intervention and can lead to favorable outcomes with radiological improvement.

151
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...

793
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

01:14Atypical Pneumonia
67
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease...

01:19Cranial and Spinal Meninges
5.0K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

15.8K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

01:25Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
