Pulmonary sequestration is a rare congenital malformation mostly located in the thorax, while intra-abdominal pulmonary sequestration is an extremely rare type of pulmonary sequestration usually diagnosed during the first 6 months of life. Only 1 case of intra-abdominal pulmonary sequestration in a patient older than 60 years has been reported in the current literature. It is difficult to differentiate an intra-abdominal pulmonary sequestration from other retroperitoneal tumors. A definitive diagnosis is always made by histologi- cal examination. Intra-abdominal pulmonary sequestration commonly responds well to surgical resection and is associated with excellent results and prognosis. The authors present the case of a 74-year-old asymptomatic man with a retroperitoneal mass which was completely excised and revealed by histopathological study to be an intra-abdominal pulmonary sequestration.
Vesical paragonimiasis is an extremely rare form of ectopic infestation caused by Paragonimus spp. We reported a case of vesical paragonimiasis associated with urinary symptoms but without history of respiratory symptoms or cercarial dermatitis. The diagnosis was made by histopathological examination of the surgical specimens of the vesical masses. Identification of the species by morphometric analysis of the fluke body sections indicated that the vesical lesion was caused by Paragonimus. Postsurgical medication with the antiparasitic drug praziquantel was applied regularly, and the patient experienced a stable recovery.
Paraneoplastic cerebellar degeneration (PCD) is one of the most common paraneoplastic neurological syndromes characterized by the rapid development of severe cerebellar ataxia. In this report, a 23-year-old female with noticeable dizziness and gait instability was described. The enhanced CT scanning suggested the presence of a pelvic tumor. Then, PCD was established. Postoperative pathological result defined it as a liposarcoma (LS) with dedifferentiation. Interestingly, clinical symptoms disappeared after the surgical removal of the pelvic tumor. To our knowledge, this was the first case report with PCD due to LS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
