Summary
Conservative management may suffice for symptomatic Rathke cleft cysts (RCCs) with inflammatory features. Hormone replacement and imaging follow-up can lead to symptom resolution and cyst shrinkage, avoiding surgery.
Area of Science:
- Neurology
- Endocrinology
- Radiology
Background:
- Rathke cleft cyst (RCC) is a benign sellar region lesion originating from Rathke pouch remnants.
- Increasing detection due to widespread brain MRI use.
- Symptomatic RCCs can cause headaches, visual disturbances, or pituitary dysfunction, often linked to inflammation.
Observation:
- A 68-year-old woman presented with headaches, polydipsia, and polyuria.
- Initial MRI showed a sellar cystic lesion; endocrinological assessment revealed arginine vasopressin deficiency.
- Serial MRI demonstrated fluctuating cyst size, indicative of intermittent inflammatory activity.
Findings:
- Conservative management, including hormone replacement and imaging surveillance, led to headache resolution and significant cyst shrinkage.
- Surgical intervention was not required for this symptomatic case.
Implications:
- Symptomatic Rathke cleft cysts with inflammatory activity may be managed conservatively.
- Individualized care and long-term monitoring are crucial, particularly for RCCs exhibiting dynamic inflammatory behavior.
- This case highlights the potential efficacy of non-surgical approaches in select RCC patients.

139
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
