What Researchers Did
Researchers reported a case of progressive radionecrosis and cyst formation in the temporal lobe of a patient who received radiotherapy for ear carcinoma.
What They Found
They found that a 73-year-old man developed an 8 x 5 x 3.5 cm cystic lesion in his left temporal lobe, along with neuropsychological symptoms, 10 years after receiving radiotherapy for basosquamous carcinoma of the left external ear canal. Symptoms improved following stereotactic aspiration of the cystic fluid and insertion of an Omaya reservoir.
What This Means for Canadian Patients
Canadian patients undergoing radiotherapy for ear canal cancers should be aware of the potential for rare, long-term complications such as brain radionecrosis and cyst formation. Early recognition and management of such complications, including surgical intervention, can help alleviate severe neuropsychological symptoms.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
As a single case report, the findings of this study cannot be generalized to a larger patient population.
