Tuberous sclerosis complex combined with primary lymphedema: A case report.

BACKGROUND:Tuberous sclerosis complex (TSC) and primary lymphedema (PLE) are both rare diseases, and it is even rarer for both to occur in the same patient. In this work, we have provided a detailed description of a patient's clinical presentation, imaging findings, and treatment. And a retrospective analysis was conducted on 14 published relevant case reports. CASE SUMMARY:A 16-year-old male came to our hospital for treatment due to right lower limb swelling. This swelling is already present from birth. The patient's memory had been progressively declining. Seizures had occurred 1 year prior at an unknown frequency. The patient was diagnosed with TSC combined with PLE through multimodal imaging examination: Computed tomography, magnetic resonance imaging, and lymphoscintigraphy. The patient underwent liposuction. The swelling of the patient's right lower limb significantly improved after surgery. Epilepsy did not occur.after taking antiepileptic drugs and sirolimus. CONCLUSION:TSC with PLE is a rare and systemic disease. Imaging can detect lesions of this disease, which are important for diagnosis and treatment.
