Zebra stripe sign: Transverse sclerotic lines in the long bones

Stripe sign in pulmonary embolism: a review of the causes.

The most common indication for radionuclide imaging of lungs is the evaluation of suspected pulmonary thromboembolism (PE). Scintigraphically PE classically produces ventilation/perfusion mismatch, that is perfusion defects in areas showing normal ventilation. Stripe sign refers to the visualization a stripe at normally perfused lung interposed between a defect and adjacent pleural surfaces as ...

The Prophylactic Effect of Methyl Prednisolone Sodium Succinate against Fat Embolism in Long Bones Fractures

In this prospective study the effect of low dose methylprednisolone succinate (10mg/kg) on the incidence of fat embolism syndrome and isolated arterial hypoxemia in 99 patients with long bone fracture (52 control and 47 steroid-trated subjects) was studied. Frequency of fractures among the selected patients was as follows: femoral fracture 52.5%, tibial fracture 36.4%, both femoral and tibial f...

Sclerotic metaphyseal lines in children and adolescents treated with alendronate.

INTRODUCTION Bisphosphonates inhibit bone resorption by interfering with the action of osteoclasts. Among the adverse effects, sclerotic lines observed in the metaphysis of long bones have been described as the main imaging finding in pediatric patients. OBJECTIVE To evaluate the frequency of radiographic changes caused by alendronate in children and adolescents with low bone density or calci...

Resection of the Long Bones

Remote cerebellar hemorrhage (zebra sign) in vascular neurosurgery: pathophysiological insights.

Hemorrhage in regions remote from the site of initial intracranial operations is rare, but may be fatal. Postoperative cerebellar hemorrhage as a complication of supratentorial surgery, with a radiological appearance known as zebra sign, is an increasingly recognized clinical entity and is associated mainly with vascular neurosurgery or temporal lobe resection. The pathophysiology remains uncle...
