Abstract. Primary pancreatic lymphoma (PPL) is a rare entity, most likely to be clinically misdiagnosed as pancreatic cancer. The cure rate of PPL is higher compared with that of pancreatic adenocarcinoma. This is the case report of a 57-year-old male patient who was hospitalized with complaints of abdominal pain, weight loss and jaundice. The radiological evaluation revealed a pancreatic head mass and, following endoscopic ultrasound-guided fine-needle aspiration biopsy, the tumor was diagnosed as diffuse large B-cell lymphoma. The final diagnosis was PPL, and the patient went into remission after receiving three cycles of treatment with rituximab, doxorubicin, cyclophosphamide, vincristine and prednisolone (R-CHOP regimen). Therefore, PPL should be considered in the differential diagnosis of pancreatic masses and its management differs from that of other types of pancreatic tumor.
Aims: To investigate the diagnostic accuracy of shear-wave elastography (SWE) for assessing malignant and benign kidneymasses.Materials and methods: Forty patients with solid renal masses underwent US elastographic evaluation. SWE values of the lesions and adjacent cortical renal parenchyma and SWER were detected prospectively. Malignant tumors were recorded as group 1 and benign tumors were recorded as group 2.Results: The highest elasticity values were 27.27±25.66 kPa for group 1 and 16.13±8.89 kPa for group 2. The mean±SD elasticity values for adjacent renal cortex for groups 1 and 2 were 2.7±2.08 and 2.75±1.35, respectively. For group 1, a negative correlation was observed between the age of the patients and SWER value (p=0.047, rs=‑0.401). There was also a negative correlation between the SWER value and the SWE value of adjacent renal cortex (p=0.004, rs=‑0.555).Conclusion: SWE is a noninvasive method that provides quantitative elasticity informationon tissues. Overlaps among different types of renal lesions may be due to heterogeneity of the lesions. Larger studygroups may clarify the other factors affecting SWE values under both normal and pathological conditions.
Knowledge regarding the variations of median nerve branching is particularly important in surgical decompression and trauma cases. A bifid median nerve together with a palmar-type median artery is a rare anatomical variation. The importance of a persistent median artery lies in the fact that the one with a large caliber may lead to an early compression of the median nerve in the carpal tunnel in patients. In the presence of a persistent median artery, surgeons must be aware regarding possibility of additional median nerve anomalies.
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.
