Dear Sir,

Cysticercosis is an important tissue cestode infestation. The infestation can be difficult to diagnose and the imaging diagnosis is usually the first preliminary diagnostic approach. However, due to the nature of tissue mass, the differential diagnosis from other tissue tumors, such as lymphoma, is needed. The report on “cysticercosis, lymphoma, and [positron emission tomography and computed tomography] (PET/CT) imaging” is very interesting. [1] Jiang et al. reported on the uncommon PET/CT finding that brings difficulty in differential diagnosis between cysticercosis and lymphoma. [1] In fact, cysticercosis is a sporadic parasitic infestation that can be seen worldwide. The clue for diagnosis in the present report by Jiang et al. is the finding of “abnormal cystic lesion.” To support the PET/CT imaging, an additional procedure is required. Fujita et al. reported the use of “a marker of neuroinflammation, translocater protein (TSPO), using PET and the selective ligand (11)CPBR28” to determine inflammation origin for support diagnosis of cysticercosis. [2] Chung et al. reported the successful usage of “carbon-11 methionine PET” for help differentiate tumor from other lesions including cysticercosis. [3] Other investigations, such as magnetic resonance imaging (MRIs) and serological tests, can also be applied for diagnosis of cysticercosis.
