RESUMO
INTRODUCTION: Reversible cerebral vasoconstriction syndrome is a complex neurovascular syndrome that presents with varying neurological deficits as well as segmental vasoconstriction of the small and medium cerebral arteries. There is limited literature on pathologies that mimic reversible cerebral vasoconstriction syndrome, so this study aims to understand what factors may impact the angiographic confirmation of reversible cerebral vasoconstriction syndrome on follow-up and play a role in establishing the diagnosis. METHODS: The Clinical Research Data Warehouse at this institution was employed to search the medical records for patients with diagnosis and treatment of reversible cerebral vasoconstriction syndrome between January 2010 and May 2021. After screening, 32 patients met the inclusion criteria for a presumed diagnosis of reversible cerebral vasoconstriction syndrome with both angiography on presentation and at three-month follow-up after treatment. Patients were divided into two categories: those with complete angiographic resolution, versus partial or no improvement on follow-up. Clinical and radiographic data were analyzed. RESULTS: Patients who had partial or no resolution were more likely to have a history of hypertension (p = 0.001), higher systolic blood pressure on admission (p = 0.047), and present with a recurrent thunderclap headache (p = 0.038). Binary logistic regression selected for hypertension (odds ratio [OR] 18.35 [95% CI, 1.37-245.1]) as predictive of not having reversible cerebral vasoconstriction syndrome, as can be seen by partial or no resolution on follow-up angiography (p = 0.028). CONCLUSION: Complete resolution on follow-up angiography is a distinguishing factor of reversible cerebral vasoconstriction syndrome. Our analysis revealed that a history of hypertension is the most significant predictor of confirming that a patient may not have reversible cerebral vasoconstriction syndrome. This is due, in part, to increased atherosclerotic or hypertensive cerebral arterial changes, which can mimic reversible cerebral vasoconstriction syndrome and present as partial or no resolution on angiography.
RESUMO
Rathke's cleft cysts (RCCs) are sellar or suprasellar cystic lesions arising from the remnants of the embryological Rathke's pouch. When symptomatic, RCCs are usually treated surgically via marsupialization. Free mucosal graft (FMG) repair has shown promise in decreasing recurrence versus marsupialization alone. The authors present a case report with operative video of a patient with visual and endocrinological symptoms with a RCC treated with FMG following marsupialization. A search of the PubMed database from July 1997 through April 2022 was conducted using the terms 'Rathke's cleft cyst', 'Rathke's cleft cyst management', 'Rathke's cleft cyst repair', 'mucosal graft', 'mucosal coupling', 'transsphenoidal', and 'endoscopic endonasal'. Clinical and pathological aspects of the case presented were compared with information obtained from literature review. A 25-year-old female presented with a six-year history of amenorrhea, one-year history of anemia, headaches, and progressive visual loss. Imaging revealed an RCC. The patient underwent surgical treatment via an endoscopic endonasal approach. Marsupialization was achieved with placement of an FMG to help prevent restenosis. Post-operative examination revealed that the patient's OD vision returned to normal, although her OS vision was only slightly improved. Our review of the English literature resulted in 35 full-length articles that were published between 1997 and 2022. The literature suggests that FMG prevents scar formation by allowing for adequate epithelialization, thus decreasing the recurrence rate and being well tolerated by patients. Our findings support the utility of the FMG as a superior surgical treatment option for RCC management.
