PHACE syndrome. PHACE syndrome is a medical condition characterized by uncommon associations between birth defects of the brain, skin (large facial infantile hemangiomas), arteries, heart and eyes. "PHACE" is an acronym for the parts of the body the syndrome usually impacts: Posterior fossa abnormalities and other structural brain abnormalities.
The Posterior cranial fossa is colored in blue, yellow, and red. The posterior cranial fossa is the part of the cranial cavity located between the foramen magnum, and tentorium cerebelli. It is formed by the sphenoid bones, temporal bones, and occipital bone. It lodges the cerebellum, and parts of the brainstem.
Collier's sign (also known as Collier's tucked lid sign [1] or posterior fossa stare [2]) is bilateral or unilateral eyelid retraction. It is an accepted medical sign of a midbrain lesion, first described in 1927 by J Collier. [3] With the eyes in the primary position, the sclera can be seen above the cornea, and further upgaze increases the ...
In 1879, the syndrome was first described in a 64 years old male by Anderson Stuart, a medical student. [1] In 1959, Hamming and Vink first described the management of the PAES in a 12-year-old patient. The patient was treated with myotomy of the medial head of the gastrocnemius muscle and concomitant endarterectomy of the popliteal artery ...
Brain herniation is a potentially deadly side effect of very high pressure within the skull that occurs when a part of the brain is squeezed across structures within the skull. The brain can shift across such structures as the falx cerebri, the tentorium cerebelli, and even through the foramen magnum (the hole in the base of the skull through ...
Platybasia is also a feature of Gorlin-Goltz syndrome, commonly known as basal cell nevus syndrome. It may be developmental in origin or due to softening of the skull base bone, allowing it to be pushed upward. The developmental variant is the result of a wider angle between the skull base of the frontal or anterior fossa and the clivus, which ...
The suboccipital triangle is a region of the neck bounded by the following three muscles of the suboccipital group of muscles: Rectus capitis posterior major - above and medially. Obliquus capitis superior - above and laterally. Obliquus capitis inferior - below and laterally. (Rectus capitis posterior minor is also in this region but does not ...
The fabella sign is displacement of the fabella that is seen in cases of synovial effusion and popliteal fossa masses. [ 1] The fabella is an accessory ossicle located inside the gastrocnemius lateral head tendon on the posterior side of the knee, in about 25% of people. It can thus serve as a surrogate radio-opaque marker of the posterior ...
