Insights
Iodide mumps, a rare condition, can occur after CT scans using iodinated contrast media like iopamidol. This case highlights the importance of recognizing this adverse reaction in patients presenting with salivary gland swelling post-procedure.
Area of Science:
- Radiology
- Endocrinology
Background:
- A 70-year-old female with a history of renal cancer underwent CT examination for metastasis assessment.
- The patient received 100 ml of iopamidol, an iodinated contrast agent.
Observation:
- Three hours post-CT, the patient developed nausea, vomiting, facial flushing, bilateral jaw pain, and fever.
- Symptoms persisted for four days, gradually decreasing in severity.
Findings:
- Laboratory results revealed elevated white blood cells and serum amylase.
- Analysis indicated 86% of amylase originated from salivary glands, consistent with iodide mumps.
- The patient was treated with anti-inflammatory therapy.
Implications:
- This case underscores the potential for iodide mumps as an adverse reaction to iodinated contrast media.
- Awareness of this condition is crucial for radiologists and clinicians managing patients post-CT.
- Further research into the incidence and management of contrast-induced sialadenitis is warranted.
Abstract:
We have experienced a case of iodide mumps after CT examination with 100 ml of iopamidol. The patient was a 70-year-old woman with a history of right nephrectomy due to right renal cancer. She underwent CT examination to explore local recurrence and abdominal metastases including lymph node and liver metastases. Three hours after the CT examination, she complained of nausea, vomiting, facial flushing, bilateral jaw pain, and fever. The laboratory findings 12 hours after CT examination showed increased white blood cells and elevated serum amylase enzyme. Analysis of the amylase fraction showed that 86% originated from the salivary glands. She was admitted to the hospital, and the symptoms continued for four days, with decreasing severity. Anti-inflammatory therapy was performed, and the patient was discharged six days after the event.
