Vague neuroglycopenic complaints camouflage diagnosis of adolescent insulinoma: a case report.

Background: Insulinoma is a rare diagnosis in the general population with estimates of 1 in 250,000 people per year. Reports of these pancreatic islet cell tumors are even more unusual in children and adolescents. Chronic hypoglycemia due to an insulinoma often presents with neuroglycopenic symptoms that can easily be overlooked, especially in adolescents where nonspecific complaints are common.

Partial anomalous pulmonary venous return through a left subaortic vein.

We present an unusual case of partial anomalous pulmonary venous return draining a subsegmental area of the left upper lobe into the superior vena cava. To our knowledge, this type of partial anomalous pulmonary venous return has not been described previously. We briefly describe embryologic considerations that we believe could help explain the origin of this rare anomaly.

Right-sided oropharyngeal cervical aortic arch.

We present a rare case of cervical aortic arch with associated spontaneously ruptured thoracic aortic aneurysm. Our case is unique in that the apex of the arch was at the level of the second cervical vertebra, the most cranial location of all reported cases. To our knowledge, this case represents the first "oropharyngeal cervical aortic arch" ever described.
