Focal epithelial hyperplasia or Heck’s disease is a rare benign lesion of oral mucosa caused by human papilloma virus especially subtypes 13 and 32. The disease is predominantly found in children and adolescents with indigenous heritage. This paper reports a unique case of Heck's disease in an 11-year-old Iranian girl with multiple, bilateral and elevated lesions on the buccal and labial mucosa...

we present a case of unilateral tibia vara associated with an area of focal fibrocartilaginous dysplasia in the medial aspect of the right proximal tibia. such a case has not been described previously. the affected child was 8 months old. deformity resolved without aggressive treatment. the pathogenesis of the focal lesion remains controversial. the most likely explanation is that the mesenchym...

Introduction: The quality of T2-weighted images (T2WI) of the liver in the clinical setting is often degraded by ghosting artifact from various sources of motion. This artifact can obscure the margins of the liver, intra-hepatic vessels, and focal liver lesions, lowering diagnostic utility. One study has noted that such motion within the liver is more severe at 3T compared with at 1.5T [1]. Fur...

Neurologic sequelae after cardiopulmonary bypass have a multi-factorial etiology. Although it is typically thought that a neurologic dysfunction means a focal lesion, symptoms of a brain disorder can be initiated by metabolic disruption such as from hyper- or hypoglycemia, hypercalcemia, renal and hepatic injury, fatigue, and anesthesia. However, one of the most important causes of acute neurol...

We report a case of a 67-year-old Caucasian man with right upper quadrant abdominal pain. He underwent radiologic investigations that revealed a solid, focal mass, at the V hepatic segment. Because a definitive diagnosis, based on imaging appearance of the lesion, was impossible in our case, we performed a hystopathological investigation but the biopsies were inconclusive. So, the definitive di...

Focal nodular hyperplasia is a benign liver lesion incidentally discovered with increasing frequency because of the proliferation of imaging studies. Radiographic characterization can diagnose this pathologic lesion and nonoperative therapy is the standard of care. However, surgical resection may be required for diagnostic reasons or symptomatic patients. Depending on the anatomic location of t...

We present the case of a young female on oral contraceptives (OCs) who was diagnosed with focal nodular hyperplasia (FNH) and remained on oral contraceptives. Months later, the patient presented with acute abdominal pain and intratumoral hemorrhage in the liver. The patient was taken to the operating room (OR) and was diagnosed with a ruptured hepatic adenoma (HA). We review the key diagnostic ...
