1 Measurement showed the septum pellucidi deviated from falx cerebrum and midline.

2 Results Bleeding only in subdural space cerebral falx or tentorium occurred in 7 and 5, 2 cases bleeding located in the base of frontotemporal region.

3 The morphology of falx cerebri and tentorium cerebelli was investigated in 3250 adult cadavers.

4 Methods 36 cases of subdural hygroma beside cerebral falx were summarized , 33 cases is traumatic, 3 cases is non-traumatic.

5 This circumscribed reddish - yellow firm neoplasm beneath the dura next to the falx is a meningioma.

6 Brain MRI displayed abnormal strengthening signals in cerebral dura mater, especially in cerebral falx and tentorium of cerebellum.

7 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.

8 A detailed US examination using a 3.5-MHz transabdominal probe demonstrated a fused single ventricle, a fused thalami, a cleft lip and palate, and the absence of falx cerebri in her fetus.

9 Objective To analyze CT features and reason of subdural hygroma beside cerebral falx.

10 Coronal image shows the midline interhemispheric fissure ( IF ), which contains the echogenic falx cerebri.

11 This circumscribed reddish-yellow firm neoplasm beneath the dura next to the falx is a meningioma. The superior parasagittal location is quite common.

12 Both occur more commonly in women during the 5th decade of life with a predilection for similar sites of involvement including the cerebral convexities, sphenoid ridge, falx,[] and tentorium.

13 Objective To study the relationship of parasagittal and parafalx meningiomas with the sagittal sinus and falx, and to discuss its MRI features.

14 Objective To evaluate CT features of subdural hematomas at cerebral falx and tentorium of cerebellum.

15 We also review the other subtypes of chondrosarcoma and discuss the differential diagnosis of an aggressive-appearing extra-axial hypervascular tumor at the falx cerebri.
