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.

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.

We report two very unusual observations in which gas and fluid effusions were transiently and unexpectedly found in the extravertebral spaces of patients presenting with painful necrotic vertebral collapse containing a vacuum cleft. We hypothesize that gas and/or fluid which progressively may replace vacuum in vertebral compression fractures could be secondarily pumped through extravertebral and retroperitoneal spaces. Although being rare, these observations may represent a potential missing link in the imaging snapshots of the cyclic and dynamic vacuum phenomenon.
