Appendiceal intussusception is a rare condition characterized by the invagination of appendix into base cecum. In some cases, this can lead to obstruction, ischemia, and perforation. It more common in elderly patients, particularly women, often associated with presence lesion, benign or malignant, acting as “lead point.” This case report details emergency management 54-year-old female patient severe abdominal pain, nausea, vomiting. The physical examination was unremarkable, were laboratory...

The loss of breast cancer cell differentiation during metastatic progression leads to a down-regulation class 1 human leukocyte antigen (HLA) expression, which in turn hinders cytotoxic T lymphocytes from effectively preventing tumor proliferation. Consequently, one would expect that decreased HLA expression correlate with 5-year survival. However, estrogen receptor alpha (ESR1) is known be positively associated overall study aimed determine the levels HLA-A, HLA-B/C, and ESR1 assess their...

Background/Aim: Class 1 human leukocyte antigen (HLA) ensures that cytotoxic T lymphocytes (CTLs) attack tumor cells. As part of de-differentiation, the expression HLA on cell surface may decrease, which can facilitate growth. Therefore, reduced is generally negatively associated with overall survival (OS). The reverse true for programmed death protein (PD-1) and ligand (PD-L1). presence PD-1 PD-L1 cancer cells inhibits immune defense mechanisms against one would expect increased PD-1/PDL-1...

Background: This study analyzed different classifier models for differentiating pancreatic adenocarcinoma from surrounding healthy tissue based on radiomic analysis of magnetic resonance (MR) images. Methods: We observed T2W-FS and ADC images obtained by 1.5T-MR 87 patients with histologically proven training validation purposes then tested the most accurate predictive that were another group 58 patients. The tumor segmented three consecutive slices, largest area interest (ROI) marked using...

The aim of this retrospective study was to present and compare the results using two different types esophageal self-expanding stents (uncovered covered) for palliative treatment patients with inoperable malignant stenosis esophagus cardia. Over a period 8 years, 152 underwent fluoroscopically guided insertion metal stents. We inserted uncovered nitinol Strecker in 54 (group I) covered Ultraflex remaining 98 II). stent procedure successively performed all patients. Closure fistula by...

Gastrointestinal metastases from invasive lobular breast cancer are uncommon with the stomach and small intestines being most common metastatic sites. Peritoneal rectal very rare only rarely occur as first manifestation of disease. We herein report case a 47-year-old woman who presented abdominal carcinomatosis sign carcinoma (ILC). Identifying important immunohistochemical markers for ILC: gross cystic disease fluid protein 15, estrogen progesterone receptors enabled correct diagnosis....

The objective of this study is to determine the morphological computed tomography features tumor and texture analysis parameters, which may be a useful diagnostic tool for preoperative prediction high-risk gastrointestinal stromal tumors (HR GISTs). This prospective cohort that was carried out in period from 2019 2022. included 79 patients who underwent CT examination, analysis, surgical resection lesion suspicious GIST as well pathohistological immunohistochemical analysis.

Background Intrahepatic mass-forming cholangiocellular carcinoma (IMC) is the second most common primary liver tumor. The differentiation between IMC and solitary hypovascular metastases (SHLM) represents a diagnostic challenge due to many overlapping magnetic resonance imaging (MRI) features. Purpose To determine value of diffusion-weighted (DWI) in addition conventional MRI for distinction intrahepatic cholangiocarcinoma metastases. Material Methods Fifty-three patients with pathologically...

Inflammatory myofibroblastic tumor (IMT) is an aggressive benign mass that may arise from various tissues and organs with a great variability of histological clinical appearances. Due to variable nonspecific imaging findings, diagnosis IMT not obtained before surgery. The aim this paper present CT MRI findings during four-year follow-up complete, spontaneous regression the uterus. was made by histology immunohistochemistry analysis open excisional biopsy specimen.

Background Pancreatic adenocarcinoma is a highly lethal disease even in initially resectable patients. Functional imaging procedures such as diffusion-weighted (DWI) and computed tomography (CT)-perfusion might facilitate preoperative prediction of factors influencing prognosis patients with pancreatic adenocarcinoma. Purpose To evaluate CT-perfusion DWI quantitative parameters to assess their correlation clinicopathological features. Material Methods Forty-four histopathologically proven...

Patients with coronavirus disease 19 (COVID-19) have increased susceptibility to secondary respiratory infections including invasive pulmonary aspergillosis (IPA). COVID-19-associated (CAPA) is difficult diagnose and can be associated mortality especially in severe immunodeficiency such as hematological malignancies. Our study evaluates IPA COVID-19 patients defined COVID-19-CAPA among acute leukemia (AL). A retrospective single-center analyzed 46 infection leukemia, admitted the Clinic for...
