İntrakraniyal Lipomu Bulunan Pediatrik Hastaların Radyolojik Bulguları

Amaç: Bu çalışmanın amacı bilgisayarlı tomografi (BT) ve manyetik rezonans görüntüleme (MRG) tetkiklerinde intrakraniyal lipom tespit ettiğimiz pediatrik hastaların görüntüleme bulgularını ve eşlik eden malformasyonları değerlendirmek ve perikallosal ile sisternal lipomları radyolojik olarak karşılaştırmaktır. Gereç ve Yöntem: Ocak 2013-Mart 2020 tarihleri arasında intrakraniyal yerleşimli lipom tespit edilen çocuk hastaların beyin BT ve MRG bulguları incelendi. Lipomların lokalizasyonları, boyutları, BT dansiteleri, şekilleri, kalsifikasyon varlığı, diğer görüntüleme bulguları ve eşlik eden anomaliler değerlendirildi. Bulgular: Çalışmaya dahil edilen intrakraniyal lipomu bulunan 17 çocuk hastanın (11 erkek ve 6 kız, 2-16 yaş arasında) 16’sında tek bir lokalizas-yonda lipom izlendi. 1 hastada farklı lokalizasyonlarda 2 lipom tespit edildi. 6 lipom perikallosal, 11 lipom sisternal yerleşimli idi. Perikallosal lipom-ların boyutu (medyan 26 mm), sisternal lipomlardan (medyan 8 mm) istatistiksel olarak anlamlı şekilde daha büyüktü (p =0.020). Sisternal lipomların şekli istatistiksel olarak anlamlı şekilde tübülonodüler idi (p =0.010). İki grup arasında yaş (p =0.733), cinsiyet (p =0.901), kalsifikasyon varlığı (p =0.653), eşlik eden anomaliler ( p =0,057) açısından istatistiksel olarak anlamlı farklılık yoktu. Hastaların en sık semptomu baş ağrısıydı. Sonuç: Lipomlar nadir konjenital intrakraniyal malformasyonlardandır. Pediatrik hastaların nörolojik gelişimleri açısından intrakraniyal lipomların erken tanısı önemlidir. Hasta takip ve tedavi yönetimi açısından radyolojik bulguların bilinmesi son derece kıymetlidir.

Radiological Findings of Pediatric Patients with Intracranial Lipoma

Objective: The aim of this study is to evaluate the imaging findings and accompanying malformations of pediatric patients with intracranial lipomas detected in computed tomography (CT) and magnetic resonance imaging (MRI) examinations and to compare pericallosal and cisternal lipomas radiologically. Material and Method: Cerebral CT and MRI findings of pediatric patients with intra-cranial lipomas between January 2013 and March 2020 were examined. Locations, sizes, CT densities, shapes, presence of calcification, other imaging findings and accompanying anomalies of lipomas were evaluated. Results: Lipoma in a single localization was observed in 16 out of 17 children (11 boys and 6 girls, between ages 2 and 16) with intracranial lipoma included in the study. Two lipomas at different localizations were detected in 1 patient, while 6 lipomas were pericallosal and 11 lipomas were located cisternally. The size of pericallosal lipomas (median 26 mm) was statistically significantly larger than cisternal lipomas (median 8 mm) (p =0.020). The shape of the cisternal lipomas was statistically significantly tubule-nodular (p =0.010). There was no statistically significant difference between the two groups with regard to age (p =0.733), gender (p =0.901), presence of calcification (p =0.653) and accompanying anomalies (p =0.057). Hea-dache was the most common symptom of the patients. Conclusion: Lipomas are rare congenital intra-cranial malformations. Early diagnosis of intracranial lipomas is important for neurological develop-ment of pediatric patients. It is extremely valuable to know radiological findings in terms of patient follow-up and management.
