Symptomatic Unilateral Subdural Effusion as the First Presentation of Suprasellar Arachnoid Cyst

Background and Importance: Arachnoid cysts are benign nontumoral lesions that are usually found incidentally in brain imaging. Suprasellar Arachnoid Cysts (SSACs) are rare. They can cause hydrocephalus and increased intracranial pressure, lower cranial nerve impairment and endocrine disorder. Sometimes arachnoid cysts become complicated by subdural hematoma/hygroma.  Case Presentation: We describe a patient with a suprasellar arachnoid cyst that was complicated with symptomatic subdural effusion and increased intracranial pressure after minor trauma. Conclusion: Although these cysts are rarely complicated with subdural hematoma/hygroma, and intracystic hemorrhage, the probability of subsequent subdural hygroma and increased intracranial pressure should not be underestimated

Symptomatic Rathke’s Cleft Cyst Presenting With Decreased Visual Acuity

Background and Importance: Symptomatic Rathke’s cleft cyst is a rare lesion that often presents without any symptoms.  Case Presentation: We report a 40-year-old female with symptomatic Rathke’s cleft cyst located in the sellar and suprasellar region. She presented with visual disturbance, headache, weight gain, hypothyroidism and amenorrhea. The patient underwent surgery and the pathological examination confirmed Rathke’s cleft cyst. Conclusion: Although the symptomatic Rathke’s cleft cyst is rare, the differential diagnosis must be done with intrasellar and suprasellar lesions
