The purpose of the present study is to investigate the possible relationship between GHD and the anatomical position of the pons as revealed by magnetic resonance imaging (MRI) in the pediatric age group.

Pathological rupture of the normal spleen: Review with the literature.

Introduction: Atraumatic spontaneous rupture of the spleen is an uncommon but fatal condition that may coexist with other disease. Our case was presented with obvious CT findings of a spontaneous rupture of the spleen.

Presentation Of The Case: A 75-year-old woman admitted to the emergency service with abdominal pain.

A ciliated foregut cyst in a gallbladder: the smallest recorded.

Ciliated foregut cysts (CFCs) are rare masses that develop from the tissues which remain from embryological foregut development. In the literature, about a hundred cases have been described in various organs so far. Although rare, there is a risk of development of squamous cell carcinoma from these cysts that typically bear benign features.

Frontal infundibular cells: pathway to the frontal sinus.

A frontal infundibular cell (FIC) is an uncommon anatomic variant of an anterior ethmoid pneumatization that originates from the frontal recess and typically extends into the lumen of the frontal sinus ostium. FICs may show several anatomic variants that impact the anatomy of the frontal recess. Familiarity with these variants is required for safe endoscopic sinus surgical procedures.

What is the importance of radiology in obstructive sleep apnea?

Lipomas are rare, and they rarely arise in deep soft tissue. Only few cases associated with obstructive sleep apnea (OSA) have been reported. Because of radiologic examinations (computed tomography and magnetic resonance imaging) in a case with OSA, a rarely observed large lipoma was encountered in the retropharyngeal region.

Age-specific size of the upper airway structures in children during development.

Objectives: The purpose of this study was to establish the largest magnetic resonance imaging study so far, by including 292 cases in a prospective fashion, to investigate the normative values of the upper airway and surrounding tissues during development.
