“…The cause of CG is believed to be trauma or infection. 1,3,8 In the present case, we reasoned that the formation of the CG was caused by hemorrhage in multiple ribs because of the surgical trauma of the right upper lobectomy performed 40 years earlier. Such a huge CG involving multiple ribs with a clear association with an antecedent surgical trauma has not been previously reported.…”

Cholesterol granuloma (CG) is a foreign body-type granuloma formed in reaction to cholesterol crystals. CG usually develops in pneumatized bones because of inadequate drainage, especially in the middle ear cavity. We report a case of a patient with huge CG involving multiple ribs. A 66-year-old man presented with chest discomfort of 8 months' duration. The chest radiograph showed a huge mass with rib destruction in the right upper lung, suggesting a malignancy. F-18 FDG PET/CT scan demonstrated large mass involving multiple ribs (right 1st-5th) with a fat component on CT, and FDG uptake in the periphery and central photopenia on PET.

“…Orbital cholesterol granulomas are uncommon orbital lesions usually localized in the superolateral cone (10,11,16 (2,20,21). Thus CT examination shows bony destruction with a soft tissue mass same as the density of brain extending extraperiosteally into the orbit and these lesions should be differentiated from dermoid tumors of the orbit.…”

AIM:Lateral orbitotomy is a well-known approach for lesions of the lateral orbital cone. It is still appropriate for laterally situated tumors although contemporary cranial base approaches were defined and developed within the last decades. MATERIAL and METHODS:Here we report 10 orbital lesions operated with lateral orbitotomy, nine of which were extraconal. Cholesterol granuloma, arachnoid cyst, pleomorphic adenoma, malign epithelial tumor, dermoid cyst, inflammatory granuloma and cavernoma were the pathologies encountered. RESULTS:The extent of lateral orbitotomy should depend on the size, consistency and nature of the lesion for easy removal and less bony resection. In this regard, contrast enhanced CT scans give useful information for operative strategy. The success of surgery can be improved and cosmetic problems can be minimized if meticulous care is taken during orbital rim resection. CONCLUSION:Although there is a wide range of histopathological diagnosis for orbital tumors, lateral orbitotomy is a safe approach, particularly if the lesions are extraconal. KEYWORDS:Arachnoid cyst, Cholesterol granuloma, Extraconal, Lateral orbitotomy, Orbital tumor ÖZ AMAÇ: Lateral orbitotomi lateral orbita yerleşimli lezyonlar için iyi bilinen bir yaklaşımdır. Kaide tümörlerine yönelik güncel yaklaşımlar son yıllarda oldukça iyi tanımlanmış olsa da lateral orbitotomi yaklaşımı halen önemini korumaktadır. YÖNTEM ve GEREÇ:Bu makalede 9'u ekstrakonal yerleşimli olan ve lateral orbitotomi ile ameliyat edilen 10 olgu sunulmaktadır. Kaydedilen patolojiler kolesterol granülomu, araknoid kist, pleomorfik adenom, malign epitelyal tümor, dermoid kist, enflamatuar granülom ve kavernomdur. BULGULAR:Lateral orbitotominin sınırı lezyonun boyutu, kıvamı ve natürü ile ilişkili olacak şekilde planlanmalı ve böylece eksizyon kolay bir şekilde ve daha az kemik rezeksiyonu ile yapılmalıdır. Bu anlamda kontrastlı BT görüntüleri operatif planlama için oldukça yararlı bilgiler sunmaktadır. Özellikle orbital rimin rezeksiyonu sırasında dikkatli olunduğu takdirde, cerrahi başarı oranı yükselirken kozmetik problemler minimale indirgenir. SONUÇ:Orbital tümörlerin histopatolojik tanısı için geniş bir tanı spektrumu olmakla birlikte, lateral orbitotomi özellikle ekstrakonal lezyonlarda güvenli bir yaklaşımdır.

“…In the head and neck region, it occurs most commonly in the middle ear and mastoid (the pneumatized areas of the temporal bone) in the setting of chronic ear disease with decreased ventilation (Aferzon et al, 2002;Shykhon et al, 2002). When affecting the orbit, it occurs almost exclusively in the supero-temporal quadrant of the orbit.…”
