Cutaneous squamous cell carcinoma (cSCC) is a common nonmelanoma skin cancer that has the potential for local invasion and spread to other tissues, so an accurate preoperative evaluation is important for treatment planning. The article describes the case of an 83-year-old female patient with a gradually enlarging mass on her head, who was examined using high-resolution 3T-MRI with microcoil enhancement. Imaging revealed a 22 × 15 × 26 mm lesion with heterogeneous signal and irregular surface extending through the epidermis, dermis, and subcutaneous fat. Surgical resection and histopathological examination confirmed moderately to well-differentiated squamous cell carcinoma (2.8 × 2.3 × 2.0 cm) without perineural invasion. Compared with conventional magnetic resonance imaging, high-resolution MRI has improved the accuracy of determining tumor boundaries and provided valuable information for preoperative planning. High-resolution MRI plays an important role in the evaluation of squamous cell carcinoma of the skin, especially in determining the depth of tumor infiltration and its differentiation from other skin malignancies, allowing early detection and more accurate surgical planning.
