Cirrhosis I: Introduction

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...

Vascular Malformations

Background:

Cystic cavernous angiomas are uncommon vascular malformations.
This study reviews 25 cases to elucidate their clinical and radiological characteristics.

Observation:

Patients predominantly women (15/25), aged 4 months to 75 years (mean 44).
Common symptoms include headache, cerebellar signs, papilledema, hemiparesis, and seizures.
Lesions primarily supratentorial (64%), cerebellopontine angle (16%), and cerebellum (20%).

Findings:

MRI reveals mixed-intensity nodules with iso- to high-intensity cysts, showing enhancement and peripheral low intensity on T2-weighted images.
Histology shows vascular channels, hemosiderin, calcification, and fibrous cyst walls with inflammation.
Total nodule removal with partial cyst resection and drainage is the preferred surgical strategy.

Implications:

Understanding the presentation and imaging features aids diagnosis of these rare lesions.
Surgical intervention is crucial for managing symptoms and preventing complications.
Further research is needed to clarify the etiology of cyst formation in these vascular malformations.
