Choked disk is rarely caused by a tumor at the base of the skull, hemorrhagic pachymeningitis, otitic smus thrombosis, or a hemorrhage at the base. A thorough exploration of the sphenoidal sinus and posterior ethmoidal cells should be conducted to identify the cause. Double choked disks are often symptoms of brain tumors but can also occur in hydrocephalus, congenital malformations, abscesses, chronic meningitis, and hemorrhages.

Choked disks can also be present in cases of nephritis, arteriosclerosis, or acute infectious diseases. When diagnosing a double choked disk with symptoms like headache, dizziness, vomiting, slow pulse, mental disturbances, and ocular issues, a brain tumor is often suspected. The nature and location of the growth remain uncertain until removed.
<Callout type="risk" title="Uncertainty in Diagnosis">The exact nature or situation of an intracranial neoplasm cannot be determined from ophthalmoscopic pictures alone.</Callout>
Symptoms such as convulsions, local spasms, muscle palsies, contractures, ataxia, dysphagia, neuralgias, areas of anesthesia, hyperesthesia, paresthesia, disorders of hearing, taste, and smell, trophic troubles, diabetes mellitus or insipidus, and albuminuria can help locate the lesion. Choked disk is a late symptom in most cases but may appear early with serious vision impairment and retinitis.
<Callout type="tip" title="Early Detection">Temporary blindness or obscuration associated with choked disk does not provide diagnostic clues.</Callout>
Choked disks can be caused by tumors at the base of the skull near the chiasm and cavernous sinus, leading to symptoms like cerebellar ataxia, facial palsy, central deafness, and loss of equilibrium. Other ocular symptoms may help in localizing brain tumors but are often indefinite or absent.
Choked disks can also occur due to hydrocephalus internus, purulent otitis media, sinus thrombosis, meningitis, abscesses, subdural abscesses, and longitudinal sinus thrombosis.
Key Takeaways
- A choked disk can be a symptom of various conditions including brain tumors, hydrocephalus, and infections.
- Thorough exploration of the sphenoidal sinus and posterior ethmoidal cells is essential for identifying causes.
- Symptoms such as headache, vomiting, mental disturbances, and ocular issues suggest a brain tumor.
Practical Tips
- Conduct a comprehensive examination to identify the cause of choked disk.
- Be aware that symptoms like convulsions or muscle palsies can help locate intracranial lesions.
- Temporary blindness associated with choked disk does not provide diagnostic clues.
Warnings & Risks
- The nature and location of an intracranial neoplasm cannot be determined solely from ophthalmoscopic pictures.
- Choked disks may appear late in the course of a tumor, making early detection challenging.
Modern Application
While this chapter focuses on historical diagnostic methods for choked disk, its insights remain relevant today. Modern imaging techniques like MRI and CT scans have improved diagnosis accuracy, but understanding the symptoms and causes described here is crucial for emergency triage.
Frequently Asked Questions
Q: What are some common causes of a double choked disk?
A double choked disk can be caused by brain tumors, hydrocephalus, congenital malformations, abscesses, chronic meningitis, and hemorrhages into the subdural or subarachnoidal spaces at the base of the brain.
Q: How does a choked disk appear in cases of nephritis?
The picture of optic neuritis presented in some cases of nephritis cannot be distinguished ophthalmoscopically from that of choked disk, indicating similar symptoms and diagnostic challenges.
Q: What are the typical symptoms associated with a brain tumor causing a double choked disk?
Symptoms include headache, dizziness, vomiting, slow pulse, mental or cerebral disturbances, convulsions, local spasms, muscle palsies, contractures, ataxia, dysphagia, neuralgias, areas of anesthesia, hyperesthesia, paresthesia, disorders of hearing, taste, and smell.
