Randomized Controlled Trial
Screening for lung cancer by imaging: the Nelson study.
The NELSON trial is the first randomised lung cancer screening trial in which pulmonary nodule management is based on volumetry. This led to considerably less false-positive referrals compared to other lung cancer screening trials, with very high negative predictive values found in the first and second screening rounds. Mortality results are still pending, but the knowledge already gained in the NELSON trial and its side-studies provide valuable information in the field of screening for lung cancer.

Biography Historical Article
A midline sagittal brain view depicted in Da Vinci's "Saint Jerome in the wilderness".
It is estimated that around the year 1480 Leonardo da Vinci painted Saint Jerome in the Wilderness, representing the saint during his years of retreat in the Syrian dessert where he lived the life of a hermit. One may interpret Leonardo's Saint Jerome in the Wilderness as St. Jerome practicing self-chastisement with a stone in his right hand, seemingly punching his chest repeatedly. ⋯ With careful analysis of the painting one can identify the skull which is hidden in an arc represented as a lion's tail. The image is of a hemicranium (midline sagittal view) showing the intracranial dura, including the falx and tentorium, and venous system with the sinuses and major deep veins. This may have been the first time when the intracranial sinuses and the major deep venous vessels were illustrated.

Supravalvar aortic stenosis (SVAS) is a form of congenital left ventricular outflow tract (LVOT) obstruction that occurs as a localized or diffuse narrowing of the ascending aorta beyond the superior margin of the sinuses of Valsalva. SVAS is a rare progressive congenital heart defect with a higher risk of sudden cardiac death. ⋯ CT and MRI angiography and eventual arteriography confirmed the diagnosis by showing a narrowing of the aorta at the sinotubular junction with significant accelerated flow. This stenosis was eventually surgically corrected with no complications.

We report a case of sudden onset of respiratory distress caused by pulmonary edema due to laryngospasm. The diagnosis was established by the clinical context and chest X-ray. A CT-scan was performed to narrow down the differential diagnosis and to confirm the diagnosis. Postextubation pulmonary edema due to laryngospasm is a rare entity with a typical clinical and radiographic presentation.
