A rare variation of the posterior cranial fossa: duplicated falx cerebelli, occipital venous sinus, and internal occipital crest.
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...
متن کاملEVALUATION OF ANATOMICAL VARIATIONS OF VESTIBULAR AQUEDUCT DIMENSIONS IN TEMPOR AL BONE CT SCAN
Various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. Both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution CT scan. It was found that in approximately one third of the patient group (with idiopathic SNHL), the vestibular aqueduct was 1.5 mm or larger. ...
متن کاملA partially ossified falx cerebri.
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...
متن کاملAutomatic Extraction of Symmetry Plane from Falx Cerebri Areas in CT Slices
We present the simple and fast symmetry plain detection algorithm, that recognizes Falx cerebri curve on each human brain computed thomogrpahy slice. Symmetry curves appear approximately on 30% images and using such images as reference it is possible to determine symmetry plane. We propose an algorithm based on hybrid methods, that allows detect symmetry plane with deviation angle until 25. The...
متن کاملMesenchymal Chondrosarcoma at the Falx Cerebri
Intracranial mesenchymal chondrosarcoma is one of the rare tumors of the central nervous system, which often presents as an aggressive-appearing extra-axial hypervascular tumor at the falx cerebri. The tumor presents mostly in young adults, while meningioma or metastatic intracranial tumor most commonly in aged people. However, its imaging findings are non-specific. In this article, we present ...
