SummaryBackgroundIntracranial neurenteric cysts are rare cystic masses of endodermal origin lined with mucin producing low columnar or cuboidal epithelium. Approximately 141 cases have been reported so far. Most of the posterior fossa neurenteric cysts are typically small, located anteriorly to the brainstem in the midline or in the cerebellopontine angle cistern area.Case ReportWe present a rare, histologically proven case of a large lobulated intracranial neurenteric cyst measuring 4.2 centimeters in the maximal transverse dimension and involving bilateral cerebellopontine angle cisterns. We also present a review of the literature on this uncommon finding.ConclusionsImaging features of neurenteric cyst are non-specific and it should be considered in the differential diagnosis for any intracranial extraaxial cystic lesion.
Undescended testis is one of the most common pediatric disorder of the male endocrine glands and the most common genital disorder identified at birth. The undescended testis may be palpable or non-palpable. Approximately 20% of undescended testis are non-palpable and either located in the abdomen or the canaliculi, or atrophic or are completely absent. Identifying the location of ectopic and undescended testes can aid in presurgical planning and help determine the optimal type of surgical correction procedure to be performed. Ultrasound and MRI are the most common imaging exams ordered to detect and locate these two variants. Testicular tissue at ectopic site was identified by presence of characteristic signal intensity pattern, mediastinum testis and its location along empty spermatic canal in cases of inguinal testis either singly or in combination. We conclude that MR imaging is useful in the localization and tissue characterization of nonpalpable testes.
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.
