ABSTRACT
Objective: To emphasize the increasing frequency of cerebral sinus venous thrombosis (CSVT) among the causes of pseudotumor cerebri (PTC) and the necessity of investigating it in patients presenting with papilledema during the COVID-19 pandemic. Material and Methods: Complete ophthalmological examinations, magnetic resonance imaging (MRI) and contrast-enhanced magnetic resonance venography (MRV) data of 44 patients diagnosed with PTC in a tertiary neuro-ophthalmology clinic, from the beginning of the COVID-19 pandemic to the present were recorded. Patients without documented increases in intracranial pressure by lumbar puncture, patients with abnormalities in cerebrospinal fluid (CSF) biochemistry and microbiology analysis, and patients with intracranial mass, obstructive hydrocephalus, or meningitis on MRI were excluded. Results: MRI and contrast-enhanced MRV imaging were evaluated together in 36 of the 44 patients with COVID-19 positivity. The mean age of the included patients was 36.9 years (minimum: 9-maximum: 63). Among these 36 patients who underwent combined imaging, 14 (38.8%) showed findings indicative of CSVT: 5 had superior sagittal sinus thrombosis, 5 had transverse sinus thrombosis, 2 had sigmoid sinus thrombosis, 1 had inferior sagittal sinus thrombosis, and 1 had extensive CSVT. Conclusion: While we had a CSVT rate of 9.2% which is compatible with previous studies before the pandemic period; in this retrospective study covering the pandemic period, we detected CSVT in 38.8% of patients with suspected PTC. We think that CSVT should be investigated in all patients who are considered to have increased intracranial pressure with combined MRI-MRV imaging.

ÖZET
Amaç: Psödotümör serebri (PTS) nedenleri arasında serebral sinüs ven trombozunun (SSVT) artan sıklığına ve COVID-19 pandemisi sırasında papilödem ile başvuran hastalarda bunun araştırılmasının gerekliliğine dikkat çekmek. Gereç ve Yöntemler: COVID-19 pandemisinin başlangıcından itibaren üçüncü basamak bir nörooftalmoloji kliniğinde PTS tanısı konan 44 hastanın tam oftalmolojik muayeneleri, manyetik rezonans görüntüleme (MRG) ve kontrastlı manyetik rezonans venografi (MRV) verileri kaydedildi. Lomber ponksiyon ile intrakraniyal basınç artışı belgelenmeyen, beyin omurilik sıvısı biyokimyası ve mikrobiyolojisi analizlerinde anormallikleri olan ve MRG'de intrakraniyal kitle, obstrüktif hidrosefali veya menenjit tespit edilen hastalar çalışma dışı bırakıldı. Bulgular: COVID-19 pozitifliği olan 44 hastanın 36'sında MRG ve kontrastlı MRV görüntülemeleri birlikte değerlendirildi. Çalışmaya dâhil edilen hastaların yaş ortalaması 36,9 idi (minimum: 9-maksimum: 63). Bu 36 hastanın 14'ünde (%38,8) SSVT lehine bulgular saptandı: 5 hastada süperior sagittal sinüs trombozu, 5 hastada transvers sinüs trombozu, 2 hastada sigmoid sinüs trombozu, 1 hastada inferior sagittal sinüs trombozu, 1 hastada yaygın serebral sinüs ven trombozu tespit edildi. Sonuç: Pandemi öncesi dönemde yapılan önceki çalışmalarla uyumlu olarak SSVT oranımız %9,2 iken, pandemi dönemini kapsayan bu retrospektif çalışmada PTS şüphesi olan hastalarda %38,8 oranında SSVT tespit ettik. Artmış intrakraniyal basınç olduğu düşünülen tüm hastalarda kombine MRG-MRV görüntüleme ile SSVT'nin araştırılması gerektiğini düşünüyoruz.
