Summary
Surgical removal of a rare ossified midbrain cavernoma successfully cured Holmes
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Midbrain cavernomas are rare, and their association with Holmes' tremor is even rarer.
- This report details a unique case of a heavily ossified cavernoma presenting with Holmes' tremor, a clinical manifestation not previously associated with surgical cure.
- The unusual features of heavy ossification and Holmes' tremor in this cavernoma are discussed.
Observation:
- A 60-year-old woman presented with Holmes' tremor as the sole manifestation of a heavily ossified thalamomesencephalic junction cavernoma.
- Neuroimaging revealed characteristic features of an ossified cavernoma.
- Surgical removal was performed via a posterior interhemispheric approach in the sitting position.
Findings:
- Complete surgical excision of the ossified cavernoma was achieved.
- The patient experienced near-complete suppression of Holmes' tremor post-surgery.
- Histological examination confirmed the cavernoma and its ossified nature.
Implications:
- This case demonstrates the first reported cure of Holmes' tremor through surgical removal of a midbrain cavernoma.
- Ossified cavernomas, despite their rarity, present a characteristic MRI signature and are potentially curable.
- Highlights the importance of considering ossified cavernomas in the differential diagnosis of intracerebral hypointense lesions.

Alterations in Muscle Tone lll
Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
Parkinson Disease ll: Pathophysiology
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
Cranial 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...

Cerebral Edema l: Introduction
Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
