Clinical image analysis of 12 patients with tuberous sclerosis complex

Abstract

Objective To analyze the clinical,CT and MRI characteristics of tuberous sclerosis complex (TSC) to raise awareness of multiple organ damage in this disease. Methods The clinical, CT and MRI characteristics of 12 cases of clinically confirmed TSC in Nanjing Jiangbei Hospital from September 2015 to June 2020 were retrospectively analyzed. Results TSC involved multiple organs and showed different changes in clinical imaging (the count of cases may overlap). In central nervous system, there were 9 cases of typical subependymal nodule, including 7 calcified nodules and 2 non-calcified nodules; 5 cases of cortical and subcortical nodule, 3 cases of white matter signal change, 1 case of subependymal giant cell astrocytoma. In abdomen,there were 8 cases of angiomyolipoma of different sizes in both kidneys (of which 2 cases were accompanied by intratumoral hemorrhage) and 1 case of multiple hepatic angiomyolipoma. In chest, there were 2 cases of pulmonary lymphangioleiomyomatosis and 1 case of cardiac rhabdomyoma. In bone, there was 1 case of multiple nodular and patchy osteosclerosis. Conclusion The analysis of clinical imaging features of TSC multi-system tumor is helpful for the diagnosis of TSC.
