Summary
Ganglioglioma (GG) in the cerebellum is rare and can be missed by CT scans. Magnetic resonance imaging (MRI) is crucial for diagnosing this brain tumor, which can be effectively managed with partial removal.
Area of Science:
- Neuro-oncology
- Neuropathology
- Neuroradiology
Background:
- Ganglioglioma (GG) is a rare primary central nervous system tumor, typically occurring supratentorially.
- Cerebellar GGs are exceptionally uncommon, with limited case reports in existing literature.
Observation:
- This report details the first known case of a cerebellar GG exhibiting supratentorial extension.
- The patient, a 29-year-old male, presented with an 11-year history of intermittent headaches.
- Initial cranial computerized tomography (CT) scans were negative, delaying diagnosis.
Findings:
- Magnetic resonance (MR) imaging revealed a space-occupying lesion in the right cerebellar hemisphere with superior extension.
- Pathological examination confirmed the tumor composed of atypical ganglion cells and astrocytes, consistent with cerebellar GG.
- The patient experienced significant symptom improvement following partial tumor removal.
Implications:
- Cerebellar GGs can evade CT detection, presenting with prolonged, nonspecific symptoms.
- MR imaging is vital for accurate diagnosis of infratentorial GGs.
- Partial resection of cerebellar GG can lead to favorable outcomes and symptom remission.

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:18Cranial Part of Parasympathetic Division
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:19Cranial and Spinal Meninges
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

01:19Cranial Nerves: Overview and Anatomy
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...
01:22Cranial Nerves: Types Part II
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
