🧠 Schwannoma
🖊 A schwannoma is a benign tumor that develops from Schwann cells, which are specialized cells that form the myelin sheath around peripheral nerves. These tumors are generally slow-growing and typically do not spread to other parts of the body.
🖊 Characteristics
- Origin: They arise from Schwann cells in the peripheral nervous system.
- Growth pattern: Usually encapsulated and slow-growing.
- Location: Can occur anywhere along peripheral nerves, but commonly found in the head, neck, and extremities.
- Genetic association: Often linked to mutations in the NF2 gene, especially in cases of multiple schwannomas.

#Neuropathology
You perform a resection of a tumor in a 45-year-old patient using a posterior fossa approach. Upon exposure, the tumor appears to arise from the dura rather than the brain parenchyma itself. The pathological specimen is demonstrated below.

🧠 Arachnoid cap cells
🖊 Arachnoid cap cells are specialized cells found in the central nervous system, specifically within the arachnoid mater, which is one of the three meningeal layers that protect the brain and spinal cord.
🖊 Structure and Location: Arachnoid cap cells are located in the arachnoid granulations, also known as Pacchionian granulations.
🖊 These granulations are small protrusions of the arachnoid mater that extend into the dural venous sinuses, particularly the superior sagittal sinus.
🖊Function: The primary function of arachnoid cap cells is to facilitate the absorption and drainage of cerebrospinal fluid (CSF) from the subarachnoid space into the venous system.

🧠 Inferior colliculus
🖊 The inferior colliculus (IC) is a crucial structure in the auditory system, located in the midbrain. It plays a significant role in processing auditory information and integrating various aspects of sound.
🖊 Structure and Function: The inferior colliculus consists of several subnuclei, each with specific roles in auditory processing.
🖊 Its primary functions include:
- Sound localization
- Analysis of temporal features
- Frequency processing
- Sound intensity analysis4
🖊 The IC serves as an important relay station in the auditory pathway, receiving inputs from lower auditory centers and projecting to higher auditory areas.

A 60-year-old woman presents with difficulty performing fine motor tasks, such as writing and buttoning her shirt. She has no resting tremor and no history of trauma or stroke. Neurological examination reveals a 4-5 Hz intention tremor in both hands, which increases as she attempts to touch a target. MRI of the brain is shown below.

🖊 The dentate nucleus is a crucial structure within the cerebellum, responsible for coordinating voluntary movements and maintaining posture and balance.
🖊 Location: Situated in the lateral part of the cerebellum, within the cerebellar hemispheres. It is one of the deep cerebellar nuclei.
Functions
🖊 Motor Control: The primary role of the dentate nucleus is to coordinate motor activities. It processes movement-related information and sends signals to various brain regions.
🖊Clinical Significance: Neurological Disorders: Damage or dysfunction of the dentate nucleus can lead to neurological problems such as ataxia, intention tremor, and other movement disorders.
