Summary
Spontaneous cerebrospinal fluid (CSF) rhinorrhoea, often misdiagnosed as rhinitis and treated with steroids, can lead to meningitis. Early diagnosis and surgical repair significantly reduce risks.
Area of Science:
- Otolaryngology
- Neurosurgery
- Rhinology
Background:
- Spontaneous cerebrospinal fluid (CSF) rhinorrhoea is a rare but serious condition.
- It can be misdiagnosed as allergic rhinitis, leading to delayed treatment.
- Topical steroid sprays are sometimes prescribed for presumed rhinitis, potentially masking CSF leaks.
Observation:
- Three cases of spontaneous CSF rhinorrhoea were diagnosed at a specialized rhinitis clinic.
- All patients had a history of long-term topical steroid spray use for presumed rhinitis.
- Diagnosis relied on clinical history and chemical pathology, as radiology was often inconclusive.
Findings:
- Spontaneous CSF rhinorrhoea is a potentially life-threatening condition that can lead to meningitis.
- Early recognition through clinical history is crucial for diagnosis.
- Surgical repair via an extracranial, trans-nasal/external ethmoid route is effective.
Implications:
- Highlighting the importance of considering CSF rhinorrhoea in patients with persistent 'rhinitis' symptoms, especially those using topical steroids.
- Emphasizing the need for accurate diagnosis to prevent severe complications like meningitis.
- Promoting minimally invasive surgical techniques for fistula repair to improve patient outcomes.
