Clinical imaging
-
To increase the awareness on intracranial papillary meningiomas (PMs) by presenting magnetic resonance imaging (MRI) findings on this disease. ⋯ Although PM is rare, it should be considered in the differential diagnosis when evaluating intracranial neoplasms. Younger patient age, as well as imaging features such as unclear tumor-brain interface, internal heterogeneity including cyst formation, irregular enhancement, signal voids of vessels, and marked peritumoral edema can help distinguish PM from typical benign meningiomas.

Case Reports
Sling left pulmonary artery with patent type IIA tracheobronchial anomaly and imperforate anus.
We present a 3-month-old boy with a type IIA sling left pulmonary artery associated with imperforate anus and rectourethral fistula. Tracheobronchial abnormalities are demonstrated using multidetector CT with 3-D volume rendering of the airways. This case represents a novel variant of an already rare entity with an unusually high right upper lobe bronchus and no evidence of associated tracheobronchial stenosis.
