Dual-Source Dual-Energy CT-Scan Confirms the Diagnosis of Ancient Hydatid Cysts Recovered from a Late Roman Burial in Amiens, France
Background: Two calcified objects recovered from an adolescent in a burial site in Amiens, France, have been previously identified as hydatid cysts using thin-section petrography. The importance of ancient hydatidosis besides the value of these unique archeological excavated materials encouraged the authors to look at this attractive subject more interdisciplinary by implementing medical radiology.
Methods: In the current experiment, which has been carried out in the Radiology Department, Tehran Heart Center (THC), Tehran, Iran, the conventional and dual-energy dual-source CT-scan was used in studying the remaining structures of the two calcified masses. The imaging procedure was carried out based on X-Ray attenuation by two different tube voltages.
Results: A high concentration of calcium sediment in the cyst walls was revealed in Hounsfield units, the measuring of the elements in CT. Taking advantage of implementing this imaging technique the oxalate calcium was also shown as the dominant component of the samples. The results were all in favor of diagnosing hydatid cysts.
Conclusion: The achieved pictorial results in the present paper have highlighted the important role of CT scan as a noninvasive confirming technique in paleopathological investigations. Using Dual-source dual-energy CT-scan in reconfirming these previously identified hydatid cysts, is an encouraging message towards the necessity of sequential studies on invaluable biological excavated pieces.
