[Diplopia as an initial symptom of intracranial tumors]
Abstract:
Among 716 patients with intracranial blastomatous changes 74 showed diplopia as a consequence of involvement of the oculomotorius, trochlearis or (and) the abducens nerve. Diplopia as primary symptom of disease was observed in 20 cases. Patients with isolated initial diplopia were on average 10 years younger than patients where diplopia occurred only in the further course of the tumour. There were no preceding other diseases demonstrable in patients with initial diplopia. Papilloedema did not occur significantly more frequently in them than in patients with diplopia as secondary symptom. In rare cases latency between occurrence of diplopia and further symptoms may be months to two years. For this reason exact neurologic and ophthalmologic follow-up controls, particularly in young patients with isolated persistent diplopia, are required.
Insights
Diplopia, or double vision, can be an early sign of intracranial tumors, especially in younger patients. Prompt neurological and ophthalmological evaluations are crucial for timely diagnosis and management.
Area of Science:
- Neurology
- Ophthalmology
- Oncology
Context:
- Intracranial tumors can affect cranial nerves controlling eye movement.
- Diplopia is a significant symptom indicating potential neurological compromise.
Purpose:
- To analyze the incidence and characteristics of diplopia in patients with intracranial blastomatous changes.
- To differentiate diplopia as a primary versus secondary symptom of brain tumors.
Summary:
- Out of 716 patients with intracranial tumors, 74 experienced diplopia due to cranial nerve involvement (oculomotor, trochlear, abducens).
- Diplopia presented as the initial symptom in 20 cases, with these patients being younger and lacking prior diseases.
- Latency between diplopia onset and other symptoms can range from months to two years, highlighting the need for vigilant follow-up.
Impact:
- Emphasizes the importance of recognizing diplopia as a potential early indicator of intracranial tumors.
- Highlights the necessity for thorough neurological and ophthalmological follow-up, particularly in young individuals with persistent, isolated diplopia.
- Informs clinical practice regarding the diagnostic and prognostic significance of diplopia in neuro-oncology.
