Meningioma seen at autopsy, as a tumor of the dura mater extending into the cranial cavity, and can be detached from the bone along with the rest of the dura mater. Small tumors (e.g., < 2.0 cm) usually are incidental findings at autopsy without having caused symptoms. Larger tumors may cause symptoms, depending on the size and location.

Frontal lobe syndrome can be caused by a range of conditions including head trauma, tumours, neurodegenerative diseases, neurodevelopmental disorders, neurosurgery and cerebrovascular disease. Frontal lobe impairment can be detected by recognition of typical signs and symptoms, use of simple screening tests, and specialist neurological testing.
The lateral sulcus divides both the frontal lobe and parietal lobe above from the temporal lobe below. It is in both hemispheres of the brain. The lateral sulcus is one of the earliest-developing sulci of the human brain, appearing around the fourteenth week of gestational age. [1] The insular cortex lies deep within the lateral sulcus. [2]
This leads to various other symptoms including headache and a swollen optic disc. The differential diagnosis for sphenoid wing meningioma includes other types of tumors such as optic nerve sheath meningioma, cranial osteosarcoma, metastases, and also sarcoidosis. Following the physical exam, the diagnosis is confirmed with neuro-imaging.
Different sutures between the frontal and parietal bones of the skull expand in specific directions, causing a symmetrically shaped human head. [3] The frontal bone and the parietal bones are joined at the frontal suture. The frontal bone has a number of parts, including the squamous part, the orbital part, and the nasal parts.
The salience network is theorised to mediate switching between the default mode network and frontoparietal network (central executive network). [1] [2] [3]The frontoparietal network (FPN), generally also known as the central executive network (CEN) or, more specifically, the lateral frontoparietal network (L-FPN) (see Nomenclature), is a large-scale brain network primarily composed of the ...
