De Novo Extramedullary Plasmacytoma of Thyroid Cartilage.

Myeloma involving the laryngeal cartilage is rare, whereas extramedullary plasmacytoma involving only the thyroid cartilage is even rarer. No case of de novo extramedullary plasmacytoma involving thyroid cartilage has been published so far. Hence, it was a diagnostic challenge for clinicians, radiologists, and pathologists.

Adding MR Diffusion Imaging and T2 Signal Intensity to Neck Imaging Reporting and Data System Categories 2 and 3 in Primary Sites of Postsurgical Oral Cavity Carcinoma Provides Incremental Diagnostic Value.

Background And Purpose: The NI-RADS lexicon doesn't use ADC parameters and T2 weighted signal for ascribing categories. We explored ADC, DWI, and T2WI to examine the diagnostic accuracy in primary sites of postsurgical oral cavity carcinoma in the Neck Imaging Reporting and Data System (NI-RADS) categories 2 and 3.

Materials And Methods: We performed a retrospective analysis in clinically asymptomatic post-surgically treated patients with oral cavity squamous cell carcinoma who underwent contrast-enhanced MRI between January 2013 and January 2016.

Combined Diagnostic Accuracy of Diffusion and Perfusion MR Imaging to Differentiate Radiation-Induced Necrosis from Recurrence in Glioblastoma.

We aimed to use quantitative values derived from perfusion and diffusion-weighted MR imaging (PWI and DWI) to differentiate radiation-induced necrosis (RIN) from tumor recurrence in Glioblastoma (GBM) and investigate the best parameters for improved diagnostic accuracy and clinical decision-making. Methods: A retrospective analysis of follow-up MRI with new enhancing observations was performed in histopathologically confirmed subjects of post-treated GBM, who underwent re-surgical exploration. Quantitative estimation of rCBV (relative cerebral blood volume) from PWI and three methods of apparent diffusion coefficient (ADC) estimation were performed, namely ADC R1 (whole cross-sectional area of tumor), ADC R2 (only solid enhancing lesion), and ADC R3 (central necrosis).

Incidental detection of Zinner syndrome in a patient with nonseminomatous germ cell tumor of testis.

Zinner syndrome is a rare congenital abnormality occurring in males comprising a triad of unilateral renal agenesis, ipsilateral ejaculatory duct obstruction, and seminal vesicle cyst. Most patients remain asymptomatic, and some may present with lower urinary tract symptoms or infertility. We present a case of incidentally detected Zinner syndrome in a patient with nonseminomatous germ cell tumor of testis, an association that is not reported in literature to our knowledge.

Infected hydrocele following laparoscopic appendectomy: case report.

In the literature, specific reported complications after laparoscopic appendectomy include bowel injury, hemorrhage, wound infection, and cecal fistula. We report the occurrence of infected hydrocele after laparoscopic appendectomy in a 20-year-old man. This complication, to our knowledge, has not yet been described in the literature.
