Sialolithiasis is the most common cause of calcifications detected with ultrasound in patients with chronic inflammatory symptoms and swellings of the salivary glands. Other differential diagnoses of calcifications are extremely rare and mostly benign. Case report and literature review. Two rare cases of malignant parotid gland tumors with calcifications in a localization typical for sialolithiasis, which were mistaken for salivary calculi based on image findings, are presented. This report intends to highlight the pitfalls in the imaging of parotid gland diseases. Even if malignant tumors of the parotid gland with calcifications are extremely rare, in ambiguous cases, differential diagnoses should be considered carefully. A high suspicion index of the need for further diagnostics in cases with calcifications is practical and could include missing periprandial symptoms, no obstruction signs in the proximal duct, and missing evidence of sialolithiasis in sialendoscopy.
涎石病是慢性炎症症状和唾液腺肿大患者中超声检测到钙化的最常见原因。钙化的其他鉴别诊断极为罕见，且大多为良性。病例报告与文献综述。本文报告了两例罕见的腮腺恶性肿瘤病例，其钙化部位与涎石病典型部位相同，基于影像学表现被误诊为唾液腺结石。本报告旨在强调腮腺疾病影像学诊断中的陷阱。即使伴有钙化的腮腺恶性肿瘤极为罕见，但在诊断不明确的病例中，仍应仔细考虑鉴别诊断。对于有钙化的病例，提高对进一步诊断必要性的怀疑指数是可行的，这可能包括无进食相关症状、近端导管无梗阻体征以及唾液腺内镜检查无涎石病证据。
