Differentiating malignant from benign splenic lesions: a meta-analysis and pictorial review of imaging features.

Objectives: Splenic lesions might exhibit overlapping imaging features, varying from benign entities like cysts and hemangiomas to malignancies such as lymphoma and angiosarcoma. This meta-analysis aims to delineate imaging characteristics that distinguish malignant from benign splenic lesions.

Methods: Adhering to PRISMA guidelines, we searched PubMed, Scopus, and Web of Science for studies on imaging features differentiating malignant from benign splenic lesions.

Benign hepatic schwannoma in a patient with chronic hepatitis B infection: A case report.

A primary benign hepatic schwannoma is an extremely rare disease with a good prognosis. A 55-year-old man with chronic hepatitis B was referred to our hospital because of jaundice, weight loss, and a hepatic lesion found during an ultrasound examination. Magnetic resonance image revealed a 55 × 120 mm solid mass lesion in the segment V and VIII of the liver.

A technical review of percutaneous sclerotherapy with bleomycin for giant hepatic venous malformation.

Background: Hepatic venous malformation (HVM), traditionally called liver haemangioma, is considered the most common benign hepatic lesion.

Methods: In this study, 107 immunocompromised COVID-19 patients were recruited as the case group, and 107 immunocompetent COVID-19 patients as the control group.

Biomechanical changes of the common carotid artery and internal jugular vein in patients with multiple sclerosis.

Purpose: Investigations of the hemodynamic changes of the venous system in patients with multiple sclerosis (MS) have shown contradictory results. Herein, the biomechanical parameters of the internal jugular vein (IJV) and common carotid artery (CCA) of MS patients were extracted and compared to healthy individuals.

Methods: B-mode and Doppler sequential ultrasound images of 64 IJVs and CCAs of women including 22 healthy individuals, 22 relapsing-remitting multiple sclerosis (RRMS) patients, and 20 primary-progressive multiple sclerosis (PPMS) patients were recorded and processed.

Percutaneous Sclerotherapy for Budd-Chiari Syndrome Secondary to Giant Hepatic Venous Malformations (Hemangiomas).

This prospective study evaluated the safety and effectiveness of percutaneous sclerotherapy in the treatment of secondary Budd-Chiari syndrome due to hepatic venous malformations (HVMs). Four patients (mean age, 40 years; 3 women) with 5 HVMs underwent 7 sessions of percutaneous sclerotherapy with a mixture of bleomycin and lipiodol. All patients had chronic Budd-Chiari syndrome, determined based on imaging findings, with the main symptom being abdominal discomfort and distention.

Objective: To investigate the predictive factors and the best predictive model for relapse in granulomatosis with polyangiitis (GPA) patients.

Methods: All patients referred to our tertiary university hospital with confirmed diagnosis of GPA based on 1990-ACR criteria and/or revised Chapel Hill nomenclature, who were followed more than 24 months between 2012 and 2021 were included. Patients were classified into relapsing and non-relapsing groups.

Percutaneous Sclerotherapy with Bleomycin and Ethiodized Oil: A Promising Treatment in Symptomatic Giant Liver Hemangioma.

Background Percutaneous sclerotherapy with bleomycin has been proven to have a potential benefit in the management of low-flow venous malformations. Liver hemangiomas are considered low-flow venous malformations. Thus, percutaneous sclerotherapy could potentially have a promising result in their management.

Neurological Manifestations and their Correlated Factors in COVID-19 Patients; a Cross-Sectional Study.

Introduction: COVID-19 might present with other seemingly unrelated manifestations; for instance, neurological symptoms. This study aimed to evaluate the neurologic manifestations and their correlated factors in COVID-19 patients.

Methods: This retrospective observational study was conducted from March 17, 2020 to June 20, 2020 in a tertiary hospital in Iran.

Predictors of the prolonged recovery period in COVID-19 patients: a cross-sectional study.

Background: The clinical course of COVID-19 may vary significantly. The presence of comorbidities prolongs the recovery time. The recovery in patients with mild-to-moderate symptoms might take 10 days, while in those with a critical illness or immunocompromised status could take 15 days.

Retrospective Review of Complications of Liver Hydatid Cyst Surgery with Emphasis on Outcomes of Omentoplasty.

Background: The outcome and complications of liver hydatid cyst surgeries with new and old techniques are not well determined. We intended to present the results of operations done for patients with hepatic hydatid cyst in an endemic area.

Methods: Data of 112 patients referred and operated for liver hydatid cyst, in Imam Khomeini Hospital complex, Tehran, Iran, from 2015 to 2018, were collected including demographic characteristics, operation parameters and complication related statistics.

A 21-year-old Pregnant Trauma Patient with Asymptomatic Fat Embolism; a Case Report.

Introduction: Fat embolism syndrome (FES) is most often associated with orthopedic trauma that typically presents 24-72 hours after the trauma with a classic triad. Only few cases of fat embolism due to lower extremity venous system had been reported.

Case Presentation: The current case report presents a pregnant woman who was referred to our emergency department with bilateral femoral open fracture.

Intractable parastomal bleeding in a portal hypertensive patient managed by direct sclerotherapy: a case report.

Patients with a stoma have 5% chance of developing parastomal varices, which tend to repetitive massive and life-threatening hemorrhages. Treatment of choice in parastomal varices have not been established, while Transjugular Intrahepatic Portosystemic Shunt (TIPS) has been revealed as the most successful measure. We report a hemodynamically unstable patient with a history of Ulcerative Colitis (UC) and Primary Sclerosing Cholangitis (PSC) with colostomy, because of colon cancer who presented with massive parastomal bleeding.

A Rare Cause of Gastrointestinal Bleeding in a 65-Year-Old Man with History of Polycythemia Vera.

Polycythemia vera (PV) is classified as a myeloproliferative disorder (MPD). Such patients are prone to both thrombotic and hemorrhagic events. Although gastrointestinal (GI) bleeding is not a prominent manifestation of PV, it would be life threatening and necessitating hospital admission and blood transfusion if it occurs.
