Background: Cysticercosis is an emerging and neglected tropical disease (NTD) that poses a serious public health concern worldwide. Disseminated cysticercosis (DCC) is an uncommon manifestation of cysticercosis, also found in China. Case presentation: We report three cases of DCC in patients living in China, with different clinical and radiological presentations. All three patients had DCC with active ocular cysticercosis, including one patient with widespread DCC caused by direct ingestion of Taenia solium eggs. The intravitreal cysticercus cyst in this patient was completely extracted entirely by 23-gauge pars plana vitrectomy, and the cyst was oval in shape on the flat mount preparation. Conclusion: The clinical presentation of DCC is highly sophisticated. The diagnosis depended on the typical radiological presentations, biopsy and flat mount preparations of the cyst.
