“…Radiologically it is important to differentiate these lesions from giant cell tumour, giant cell reparative granuloma, hemorrhagic cyst, plasmacytoma or fibrous dysplasia. The surgical method of choice is the complete excision of the lesion (4,21,22). Our case was 11 years old and this was similar to previous case reports although it was different from them with regards to gender.…”

Sinonazal bölgedeki benign kemik kitlelerini, sinonazal bölge ve komşu yapılarla ilişkisinin radyolojik olarak değerlendirilmesi. Yöntem: Sinonazal bölgeden 2010-2016 yılları arasında elde edilen çok kesitli bilgisayarlı tomografi (ÇKBT) ve manyetik rezonans görüntüleme (MRG) bulguları retrospektif olarak değerlendirildi. Radyolojik bulgulara dayanarak, büyüklükleri nedeniyle nadir görülen 41 olgu, histopatolojik özellikler ve lokalizasyonları çalışmaya dahil edildi. Bulgular: Kırk bir olgunun 22'inde osteoma, 16'sında fibröz displazi, diğerlerinde anevrizmal kemik kisti, enkondrom ve brown tümör vardı. Sonuç: Sinonazal bölgenin iyi huylu kemik tümörlerini görüntülerken, ÇKBT ve MRG en sık kullanılan yöntemlerdir. Radyografi, bazı durumlarda bir lezyonun varlığını gösterebilir, ancak lezyonun doğasını ve lezyon ile komşu yapılar arasındaki ilişkileri belirlemekte yetersizdir.

Aneurysmal Bone Cysts of the Paranasal Sinuses: The Mayo Clinic Experience and Review of the Literature

et al. 2021

Objective/Hypothesis Aneurysmal bone cysts (ABCs) are benign, lytic bone lesions, which rarely present in the paranasal sinuses. There is no published consensus on the appropriate diagnostic or treatment approach. Our objective was to elucidate the clinical behavior, treatment, and outcomes for patients with ABCs of the paranasal sinuses (psABCs). Study Design Retrospective case series and system review of the literature. Methods A retrospective chart review was performed to identify patients evaluated at the authors' institution with psABC and consolidated with literature reports of psABC. Results Eighty‐nine patients met inclusion criteria. The most common presenting symptom was painless facial swelling (n = 35, 39%). The ethmoid sinuses were the most common site involved (n = 55, 62%). Surgical approach was reported in 74 cases including 20 endoscopic and 54 with an open or combined approach. Fifty‐nine patients (71%) underwent gross total resection. Follow up data was reported for 67 patients. Fifteen patients (22%) were found to have recurrence or progression at follow up; 10/15 (66%) patients within the first 12 months, 14/15 (93%) within the first 24 months, and 1/15 (7%) greater than 24 months after treatment. Patients were more likely to have recurrence/progression if they presented with nasal discharge (P = .05), proptosis (P = .01), or orbital involvement (P = .03). Conclusions psABCs typically present with painless swelling or nasal obstruction. Orbital involvement is a negative prognostic indicator with these patients more likely to have recurrence after treatment. Recurrence or progression of disease is most likely to occur within 2 years after treatment. Therefore, patients should be monitored closely during this time.

“…CT usually shows a heterogeneous mass with solid and cystic regions. 7 Reports state that 87% appear as radiolucent and only 2% are radiopaque with the rest having mixed opacity. 7,8 Other findings also include ground-glass density, osseous expansion, narrowing of the foramina and contrast enhancement.…”

Aneurysmal bone cyst on top of fibro-osseous lesion of the ethmoid sinus with orbital and intracranial extension in a child

et al. 2022

Objective: Aneurysmal bone cysts (ABCs) rarely involve the cranium. We report a case arising in the ethmoid sinus with orbital and intracranial invasion. Imaging suggested an associated fibro-osseous lesion. The lesion was completely resected. Histology confirmed the imaging diagnosis of ABC on top of an ossifying fibroma. A multi-disciplinary approach is essential for optimal surgical outcomes. Methods: We report a case of an 8-year-old boy with a 5 week history of painless, increasing prominence of the left eye. Clinical examination revealed non-pulsatile left proptosis. Visual acuity and ocular movements were normal. CT and MRI scans of the maxillofacial regions showed a large space-occupying lesion involving the left ethmoid air cells with left orbital and left inferior frontal intracranial extension. Multiple fluid levels with blood products were seen. Areas of the bony component of the lesion showed ground glass density on CT. Imaging was consistent with an aneurysmal bone cyst with an underlying fibro-osseous lesion; probably fibrous dysplasia which was confirmed after surgical removal of the lesion. A multi disciplinary team of maxillo-facial, neurosusugery and ENT surgeons performed the surgery. Results: Aneurysmal bone cyst arising from an osseous fibroma of the skull is rare. Total resection can be achieved with a multi-disciplinary surgical approach. Post-operative histology confirmed by the imaging findings.
