Summary
This study reports a rare geniculate ganglion meningioma with calcifications, a unique finding confirmed by imaging and histology. This case advances understanding of intratemporal meningiomas.
Area of Science:
- Neuro-oncology
- Radiology
- Pathology
Background:
- Meningiomas typically occur in intracranial locations, with geniculate ganglion involvement being exceptionally rare.
- Intratemporal meningiomas pose diagnostic challenges due to their unusual location and potential for subtle imaging findings.
Observation:
- A case of meningioma intrinsic to the geniculate ganglion is presented.
- High-resolution computed tomography (HRCT) revealed geniculate ganglion erosion, facial canal enlargement, and intralesional calcifications.
- Magnetic resonance imaging (MRI) demonstrated intermediate T1-weighted and mild T2-weighted hyperintensity.
Findings:
- Histological examination confirmed the presence of calcifications within the meningioma.
- This represents the first reported case of a geniculate ganglion meningioma with calcifications.
- The imaging features, particularly calcifications, were key in suspecting the diagnosis.
Implications:
- The presence of calcifications in geniculate ganglion lesions should raise suspicion for meningioma.
- This case expands the spectrum of imaging findings for geniculate ganglion tumors.
- Accurate diagnosis through advanced imaging is crucial for appropriate management of these rare tumors.

01:19Cranial and Spinal Meninges
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...

01:18Cranial Part of Parasympathetic Division
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.

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...
01:18Viral 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...
01:24Peripheral Nervous System: Ganglia and Nerves
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

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...
