Computed Tomography-Derived Extracellular Volume Fraction and Splenic Size for Liver Fibrosis Staging.

Objective: Extracellular volume fraction (fECV) and liver and spleen size have been correlated with liver fibrosis stages and cirrhosis. The purpose of the current study was to determine the predictive value of fECV alone and in conjunction with measurement of liver and spleen size for severity of liver fibrosis.

Methods: This was a retrospective study of 95 subjects (65 with liver biopsy and 30 controls).

Long-Term Survival in an Adolescent and Young Adult with Metastatic Relapse of an Undifferentiated Embryonal Sarcoma of the Liver.

Undifferentiated embryonal sarcoma of the liver (UESL) is an extremely rare and aggressive malignancy in adults. Adults with UESL have a worse prognosis compared to pediatric population. Due to the rarity of this disease in adults, there has been a lack of information that assists in treatment decisions within this group.

Survival outcomes of intracranial extraventricular neurocytomas: a systematic review and individual patient data meta-analysis.

Objective: The rarity of intracranial extraventricular neurocytomas (EVNs) has precluded accurate definition of its surgical characteristics to date. The authors present the first survival analysis of this unique entity that aims to clarify tumor characteristics, surgical outcomes, and efficacy of postoperative adjuvant therapy.

Methods: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Contribution of Somatic Ras/Raf/Mitogen-Activated Protein Kinase Variants in the Hippocampus in Drug-Resistant Mesial Temporal Lobe Epilepsy.

Importance: Mesial temporal lobe epilepsy (MTLE) is the most common focal epilepsy subtype and is often refractory to antiseizure medications. While most patients with MTLE do not have pathogenic germline genetic variants, the contribution of postzygotic (ie, somatic) variants in the brain is unknown.

Objective: To test the association between pathogenic somatic variants in the hippocampus and MTLE.

Intraductal tubulopapillary neoplasm.

A man aged above 70 years old with a medical history of ulcerative colitis presented with unintentional weight loss. A pancreatic mass associated with pancreatic duct dilatation was detected on imaging procedures. Initial investigations including fine needle aspiration and cytology examination were inconclusive.
