Utility of 3D double-echo steady-state with water excitation (3D-DESS-WE) in diagnosing intraparotid facial nerve schwannoma: A case report.

Differentiating intraparotid facial nerve schwannoma from other parotid tumors, particularly pleomorphic adenoma, is clinically crucial due to significant differences in treatment approaches. We report a case of a male patient in his 70s presenting with a left parotid mass. Magnetic Resonance Imaging (MRI) revealed a mass within the left parotid gland exhibiting the characteristic ``target sign''.

Objects: To investigate the specific manifestations of neurogenic and non-neurogenic tumors involving peripheral nerves on contrast-enhanced magnetic resonance neurography (CE-MRN) and explore the potential of CE-MRN in aiding differential diagnosis.
Materials And Methods: Twenty-nine patients with neurogenic tumors and 23 with non-neurogenic tumors involving peripheral nerves were enrolled in this study. Both routine MRI and CE-MRN scanning were performed on all subjects.

Spinal cord tuberculoma is a clinically significant form of extra-pulmonary tuberculosis, despite its rarity. It leads to considerable neurological deficits and morbidity. Accurate diagnosis and early intervention depend on radiologic imaging, typically MRI, which reveals T2 hypointensity with rim enhancement, forming a ``target sign'' characteristic of caseous stage tuberculoma.

Objective: This study explored prenatal ultrasound markers in patients with anorectal malformations (ARMs).
Methods: All patients treated for ARM in our institution from January 2014 to December 2021 with an available expert fetal anomaly scan (eFAS) were reviewed. The eFAS images were assessed to evaluate the fetal anus, specifically by identifying hyperechoic anal mucosa surrounded by hypoechoic anal sphincter, referred to as "target sign" (TS).
The "target sign": A hallmark of lupus enteritis.
