INTRODUCION Intracranial chondroma is a very rare, slow growing, benign cartilaginous tumor that arises usually from the base of the scull. Chondroma located at the falx is extremely rare. According to our best knowledge 15 cases of falx chondromas have been reported in the literature. CASE OUTLINE This is the first case report of falx chondroma located in the parietal area associated with hy...

chondroma is a benign tumor which mostly occurs in extremities but also sometimes in brain. most intracranial chondromas arise from skull base, but chondroma of falx origin is a rare circumstance. indeed, the intracranial chondromas rise from falx is mostly in relation with syndromic disorders such as mafucci's syndrome or ollier's syndrome. here, we reported a rare case of falxian intracranial...

Folds of the meningeal layer of the dura mater, the falx cerebri and tentorium cerebelli, traverse the vertebrate intracranial cavity and thus compartmentalise the brain. The falx cerebelli, another dural fold, is found in the posterior cranial fossa and attaches to the inferior aspect of the tentorium cerebelli and to the internal occipital crest. We present a case of a duplicated falx cerebel...

OBJECTIVE To describe the first trimester diagnosis of agenesis of the corpus callosum (ACC). METHODS The midbrain and falx cerebri were examined in stored images of the midsagittal view of the fetal brain at 11(+0)-13(+6) weeks' gestation from 15 fetuses with ACC and 500 normal controls. The midbrain diameter and falx diameter were measured and their ratio was calculated. The values in fetus...

During a routine faculty prosection of the head and neck region of an adult female cadaver, a partial ossification of the falx cerebri was found. Ossification of other dural areas or regions of the body were not found. In addition, the brain and remaining organs appeared to be grossly normal. Reports of partial ossification of the falx cerebri are still rare and while certain pathologies such a...

Variations of the dural folds and the dural venous sinuses are seldom reported in the extant medical literature. Such variations in the posterior cranial fossa may be problematic in various diagnostic and operative procedures of this region. We report our observation of an extremely rare variation of the falx cerebelli and posterior cranial fossa venous sinuses encountered upon dissection of a ...

To determine the normal appearance of the flax and interhemispheric fissure, 200 consecutive normal CT scans were evaluated prospectively. On unenhanced scans, the normal falx is visualized in 90% of patients and therefore interhemispheric hyperdensity alone should not be considered a sign of subarachnoid hemorrhage. The flax is most often (88%) visualized in the posterior part of the interhemi...

Using intravital microscopy in a chronic in vivo mouse model, we studied the demarcation of myocutaneous flaps and evaluated microvascular determinants for tissue survival and necrosis. Chronic ischemia resulted in a transition zone, characterized by a red fringe and a distally adjacent white falx, which defined the demarcation by dividing the proximally normal from the distally necrotic tissue...
