Neurosurgeons indicated that the tumor on the parietal region of calvarium
was expansive, showed invasion into the brain parenchyma and caused brain edema.
I would use scissors to cut the neck and separate - I am not in the uterus, I am in the vagina - separating the fetal calvarium
from the fetal body.
The chronic presence of an arachnoid cyst thins and remodels the inner table of the calvarium
, which is suggestive of the diagnosis and is seen best on CT with bone windows (Figure 5).
The margin of bone where the preorbital diverticulum and calvarium
met was mildly irregular and evidence of bony lysis was visible.
In the first case, the skull of a male adult exhibits a circumferentially cut calvarium
These less-frequent patterns are reported to be more common in the calvarium
and gnathic bones (39,40) and may result from local factors, such as different structural characteristics of affected bones.
Using native fluoroscopic roadmap guidance and sterile ultrasound, the arterialized venous pouch lying along the left retromastoid calvarium
was punctured with a 21-gauge micropuncture needle.
7) A small island of split calvarium
was harvested from the posterior midfrontal bone and remained attached to the frontal pericranium (figure 2, A).
1) Extracranial extension is more commonly to the orbits, external table of the calvarium
, temporal bone and paranasal sinuses.
An area of minimal loss of definition along the internal wall of the calvarium
could be appreciated.
3,6,8,10) The skull base and calvarium
are also common sites of involvement.
Although osteoblastoma occurs in the maxilla and calvarium
, it is very rare in the paranasal sinuses, nasal cavity, and orbit.
