Abstract:
Extra-axial hydatid disease (HD) is rare and may create a diagnostic challenge. Herein, we report an extremely rare case of calvarial HD with superior sagittal sinus invasion and an extension to the scalp with unusual magnetic resonance imaging findings simulating osteomyelitis and abscess. Recognition of detached endocystic membranes was the most important clue for the correct diagnosis. HD should be included in the differential diagnosis for a patient having a destructive skull lesion with peripheral enhancing extra-axial soft tissue component. Preoperative correct imaging diagnosis is crucial to improving patient management.

Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
