Intramuscular cavernous hemangiomas arising from masseter muscles

Öz

Intramuscular hemangiomas are rarely seen benign tumors, constituting %1 of all hemangiomas. They mostly occur in the trunk and extremities. They are uncommon in the head and neck region and arising most frequently from masseter and trapezius muscle. The patients usually complain about progressive and painless swelling in facial-parotid region. Due to its location, 90% of all intramuscular hemangiomas are misdiagnosed and often clinically mistaken as a parotid swelling. Radiologic images play important role for diagnosis of these hemangiomas.

Masseter adalesinden köken alan intramuskuler kavernöz hemanjiyom

Öz

Tüm hemanjiyomların %1\'ini oluşturan intramuskuler hemanjiyomalar nadir görülen benign tümörlerdir. Sıklıkla gövde ve ekstremitelerde görülebilmektedir. Masseter ve trapezius kaslarından köken alabilen bu oluşumlar baş ve boyun bölgesinde nadir izlenmektedir. Hastalar genellikle parotis ve yüz bölgesinde zamanla büyüyen ağrısız kitleden şikayet eder. Lokalizasyonundan dolayı intramuskuler hemanjiyomaların %90\'ında klinik olarak yanlışlıkla parotis kitlesi tanısı konulabilir. Bu kitlelerin tanısında görüntüleme yöntemleri önemli yer tutar.

Anahtar Kelimeler

• İntramuskuler hemanjiyom, baş ve boyun kasları, görüntüleme yöntemleri.
