A metastatic glomus jugulare tumor. A temporal bone report

Area of Science:

• Otolaryngology
• Neurosurgery
• Oncology

Background:

• Glomus jugulare tumors, rare paragangliomas arising in the temporal bone, can exhibit aggressive behavior.
• Metastatic potential of glomus jugulare tumors is uncommon but associated with high malignancy.

Observation:

• A patient presented with classic symptoms of a primary malignant ear tumor, including facial paralysis, otorrhea, pain, hearing loss, tinnitus, dizziness, and vertigo.
• Clinicopathologic examination of the temporal bone revealed a highly malignant, metastasizing glomus jugulare tumor.

Findings:

• The tumor demonstrated aggressive local invasion and metastatic potential.
• Multimodal treatment was initiated, including cobalt irradiation and radium implant for residual tumor.
• Surgical intervention with a left-sided radical mastoidectomy was performed post-radiation therapy.

Implications:

• This case highlights the importance of considering malignant potential in glomus jugulare tumors.
• Aggressive treatment strategies may be necessary for advanced or metastatic disease.
• Further research into the molecular mechanisms driving metastasis in these tumors is warranted.
