Sir,The recent publication on cysticercosis and ptosis is very interesting.[1] Netravathi et al. reported an uncommon presentation of neurocysticercosis and concluded that “Patients with ptosis need to be evaluated for other rare central cause especially when neostigmine test is negative.”[1] Indeed, the ptosis due to parasitic infestation is not rare in tropical countries.[2] It should be noted that not only central neurocysticercosis but also ocular cysticercosis can induce ptosis.[3] Hence, the investigation of unexplained ptosis without neostigmine should start from the problem at the ocular and the surrounding areas then the central nervous system.Other rare disorders, including the malignancy, should also be included in differential diagnosis.[4]
