Neoplastic and Non-neoplastic Lesions of the Skull: Single-Center Experience

Özet

Introduction: Tumor lesions of the skull bones are extremely rare; they are usually slow-growing but clinically aggressive. They constitute approximately 1% of all bone tumors. Although they are usually benign, malignant and metastatic lesions may also be seen. This retrospective study aimed to emphasize the importance of the histo-pathological diagnosis and surgical excision amount inplanning the treatment in advance. Methods: In this study, the age and gender distribution of the cases, the location of the lesions, the surgical method, histopathological diagnoses and the preferred cranioplasty methods were included over 17 cases that were operated by our clinic between 2010-2020. Nine cases were male (52%) and eight cases were female (48%). When the diagnosis was made, the mean age was 24.3 (2 years-49 years) in the cases, while seven of the cases were children (3 girls, 4 boys). In our study, children under 17 were considered as childhood. Results: The patients’ admission symptoms were palpable pain-free mass (n=9), painful mass (n=4), visual field defect and/ or vision loss related to lesion location, focal neurological deficits due to 7th cranial nerve involvement. (n=1), exophthalmos (n=1), and one patient was an incidental diagnosis while examined for primary disease. Lesions exerted locations in the frontal bone (frontal bone and orbital roof ) (n=9), occipital bone (occipital bone and clivus) (n=5), sphenoid bone (sphenoid wing and paracellar (n=1), and lesions were multiple in two cases (n=2). One patient had a diagnosis of metastatic leiomy- oma before admission and one had multiple myeloma, while the other patients had no known chronic diseases. Discussion and Conclusion: Lesions of the skull bones are rare in the clinic. Following the detailed clinical and radiological evaluation for these lesions, the total excision of the lesion to the extent possible is particularly important for the prognosis of the disease.
