MRI analysis of relative tumor enhancement in liver metastases and correlation with immunohistochemical features.

Objective: Investigate the association between the relative tumor enhancement (RTE) of gadoxetic acid across various MRI phases and immunohistochemical (IHC) features in patients with liver metastases (LM) from colorectal cancer (CRC), breast cancer (BC), and pancreatic cancer (PC).

Methods: A retrospective analysis was conducted on 68 patients with LM who underwent 1.5-T MRI scans.

Associations between Dynamic Contrast-Enhanced Magnetic Resonance Imaging with Histopathological Features in Cholangiocarcinoma.

Introduction: The relationships between histopathology and imaging remain elusive, and investigating the underlying reasons for tumor microstructure leading to an imaging phenotype is of clinical importance. In the present study, a cross-sectional guided biopsy specimen was used to correlate prebioptic magnetic resonance imaging (MRI) with immunohistochemical staining of the histopathologic specimen using precise spatial biopsy localization.

Methods: Twenty-seven patients with mass-forming cholangiocarcinoma (CCA) were included in the present analysis.

Surgical Outcome and Microbial Colonization of Standardized Smear Locations after Pancreatic Head Resection (Pylorus-Preserving Pancreatoduodenectomy, PPPD) for Chronic Pancreatitis and Pancreatic Head Carcinoma.

Patients with chronic pancreatitis (CP) as well as with pancreatic head carcinoma (CA) undergo the surgical intervention named "pylorus-preserving pancreatoduodenectomy according to Traverso-Longmire (PPPD)", which allowed a comparative analysis of the postoperative courses. The hypothesis was that patients with CA would have worse general as well as immune status than patients with CP due to the severity of the tumor disease and that this would be reflected in the more disadvantageous early postoperative outcome after PPPD. : With the aim of eliciting the influence of the different diagnoses, the surgical outcome of all consecutive patients who underwent surgery at the Dept.

Uncommon diagnosis of multinodular goiter - isolated extrapulmonary manifestation of sarcoidosis in thyroid gland (scientific case reports).

Aim: By means of the scientific description of two uncommon cases who underwent. surgical resection of multinodous goiter and following histopathological investigation revealing isolated extrapulmonary manifestation of sarcoidosis, this uncommon diagnosis including symptomatology, clinical findings, diagnostic and therapeutic management is to be illustrated.

Case Descriptions: Diagnostics: Scintigraphy of the thyroid gland with a left-thyroid cold node; ultrasound-guided puncture (cytological investigation, non-suspicious).
