Abstract:
Parapharyngeal tumors are less common in clinical practice and are often difficult to diagnose upon clinical examination due to the anatomic complexity of the region. We report a rare case of extracranial parapharyngeal space meningioma presenting as a cervical mass with encasement of cranial nerves giving tram track appearance and features on various imaging modalities [Radiographs, Ultrasound, Computed tomography (CT) scan and Magnetic resonance imaging (MRI)].
Insights
Parapharyngeal tumors are rare and challenging to diagnose clinically. This case highlights an extracranial meningioma presenting as a cervical mass with characteristic imaging findings.
Area of Science:
- Neurosurgery
- Oncology
- Radiology
Background:
- Parapharyngeal tumors are uncommon and diagnostically challenging due to complex anatomy.
- Early diagnosis is crucial for effective management of parapharyngeal space lesions.
Observation:
- A rare case of an extracranial parapharyngeal space meningioma was observed.
- The tumor presented as a cervical mass, encasing cranial nerves.
Findings:
- Imaging studies including radiographs, ultrasound, CT, and MRI revealed specific features.
- The "tram track" appearance on imaging indicated cranial nerve encasement by the meningioma.
Implications:
- This case underscores the importance of advanced imaging in diagnosing rare parapharyngeal tumors.
- Recognizing imaging patterns aids in differentiating meningiomas from other cervical masses.
