  • Mineral foreign bodies (stones) are infrequent findings in clinical and radiological practice. However, a growing number of reports indicate that they raise clinical and diagnostic concern in ophthalmology, neurosurgery, maxillofacial surgery, otolaryngology, gastroenterology, and vascular surgery. Dense finding in the soft tissue without clear history of foreign body penetration may represent diagnostic challenge mimicking calcifications or bony fragments. The aim of this work is to analyze the appearance of stone foreign bodies on radiographs and computed tomography. A collection of minerals and rocks was used for analysis. The clinical case of a stony foreign body which penetrated into the soft tissue of the leg is used to demonstrate the diagnostic challenge and management. Available literature describing imaging characteristics of stones was reviewed. The results of this work will help in diagnostic interpretation and assessment of stone foreign body composition.
