Aneurysmal bone cyst of clivus and c1 c2 – case report and review of literature

Abstract

Aneurysmal bone cyst are benign rapidly expanding bone destructive lesions of any bone. They are common in the metaphysis of long bones but 10-30% involve the spine. Cervical region involvement is uncommon. We report a case of aneurysmal bone cyst of clivus C1 and C2 with minimum symptoms. Involvement of C1 and clivus separately had been reported in past, but simultaneous involvement of both is presented in this report for the very first time.KeywOrds: Aneurysmal bone cyst, Spine, Clivus ÖZAnevrizmal kemik kistleri herhangi bir kemikte görülebilen iyi huylu ancak tutmuş olduğu kemikte hızla genişleme yaparak harabiyete neden olur. Uzun kemiklerin metafizlerini yaygın olarak tutmakla beraber yüzde 10-30 oranında omurgada tutulum yapabilir. Servikal bölge tutulumu nadirdir. Klivus, servikal 1 ve 2. omurlarında anevrizmal kemik kistine bağlı tutulumu olan ve minimal semptomu olan hasta olgu olarak sunulmaktadır. Geçmişte, clivus veya servikal 1. omurun anevrizmal kemik kisti ile tutulumu ayrı vakalar halinde sunulmuştur, bizim olgumuz ise eşzamanlı olarak klivus ve servikal 1-2 omurgalarının aynı olguda tutulması ilk kez sunulmaktadır.

Une localisation rare au sphénoïde d’un kyste osseux anévrysmal

“…Sur le plan clinique, au niveau du sphénoïde, le kyste osseux anévrysmal est insidieux et peu bruyant. La symptomatologie clinique est liée à la destruction osseuse environnante et aux structures anatomiques comprimées au contact de la lésion en première ligne desquelles on trouve par ordre de fréquence les céphalées, une paralysie des paires crâniennes ou des signes d'obstruction nasale [ 1 , 3 , 4 ]. Dans de rares cas, des perturbations du bilan hormonal peuvent être retrouvées ce qui était le cas dans notre observation; elles seraient due à un effet d'entrainement par compression de la tige pituitaire.…”

Aneurysmal Bone Cyst Presenting as a Pathologic Fracture in a 12-Year-Old Football Player

“…The most often reported presentations of ABCs of the spine are slow, insidious onset of pain and neurologic compromise. 1,4,6,[9][10][11][12] Most reported cases of pathologic fracture associated with ABCs were the result of vertebra plana rather than posterior arch fracture. 9,13,14 In the presented case, the patient reported no previous neck pain prior to the collision.…”

Aneurysmal bone cyst on the left zygomatic arch concomitant with bilateral inferior turbinate gasification in an adult female: A case report

“…The majority of ABC cases occur in the spine or long bones of female patients less than 20 years old (6,7). In general, the pathophysiology of ABC is consequential rather than causal, induced by hemodynamic abnormalities in local blood vessels due to giant cell tumor, osteochondritis, hemangioma, chondroblastoma or trauma.…”
