Frontal arachnoid cysts have been associated with depression. [12] Cysts on the left temporal lobe have been associated with psychosis. [13] [14] A left fronto-temporal cyst showed symptoms of alexithymia. [15] Cyst on the right sylvian fissure resulted in new onset of schizophrenia-like symptoms at age 61. [16]
Porencephaly is an extremely rare cephalic disorder involving encephalomalacia. [1] It is a neurological disorder of the central nervous system characterized by cysts or cavities within the cerebral hemisphere. [2] Porencephaly was termed by Heschl in 1859 to describe a cavity in the human brain. [3] Derived from Greek roots, the word ...
Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe of the brain due to disease or frontal lobe injury. [5] The frontal lobe plays a key role in executive functions such as motivation, planning, social behaviour, and speech production. Frontal lobe syndrome can be caused by a range of conditions including ...
Epidermoid cyst. Relative incidence of cutaneous cysts, where epidermoid cysts constitute a plurality (blue area). An epidermoid cyst or epidermal inclusion cyst[1] is a benign cyst usually found on the skin. The cyst develops out of ectodermal tissue. Histologically, it is made of a thin layer of squamous epithelium.
Seizures and delays in motor development are also prevalent. Additionally, mild mental retardation can be observed. Patients often exhibit diffuse swelling of the cerebral white matter and large subcortical cysts in the frontal and temporal lobes, with cysts developing on the tips of the temporal and subcortical areas.
Dermatology, general surgery. A sebaceous cyst is a term commonly used to refer to either: [1] Epidermoid cysts (also termed epidermal cysts, infundibular cyst) Pilar cysts (also termed trichelemmal cysts, isthmus-catagen cysts) Both of the above types of cysts contain keratin, not sebum, and neither originates from sebaceous glands.
A frontal horn cyst or connatal cyst is a cystic area in the brain. It is sometimes found in newborn babies with an incidence rate of 0.4-6%. It is adjacent to the superolateral margin of the body and frontal horn of the lateral ventricles, and is believed to represent a normal variant with no effect on neurological development.
The frontal lobe is the largest lobe of the brain and makes up about a third of the surface area of each hemisphere. [3] On the lateral surface of each hemisphere, the central sulcus separates the frontal lobe from the parietal lobe. The lateral sulcus separates the frontal lobe from the temporal lobe. The frontal lobe can be divided into a ...
