RESUMO
Squamous cell carcinoma of the eyelid is a rare but severe tumor that causes functional and aesthetic damage and poses a significant threat to life through metastatic spread. It typically affects elderly individuals with fair skin and often develops from pre-existing lesions. Diagnosis is confirmed by biopsy. Imaging, using CT and MRI, is critical for assessing local and distant extension, guiding treatment, and monitoring progress. Primary treatment is surgical, aiming for complete resection and restoration of eyelid function, with radiotherapy or chemo-radiotherapy considered for metastatic cases on an individual basis. This report presents a case of unusual localization of eyelid SCC metastasis, showing the importance of performing a cross sectional imaging, particularly a CT NCAP, for distant extension assessment.
RESUMO
Pneumosinus dilatans (PSD) is an abnormal dilatation and enlargement of one or more paranasal sinuses, extending beyond the anatomic bony boundaries, without defect or thinning of its bony walls. It is documented by only a few reports. Usually asymptomatic, it is in general found incidentally on imaging. It is important for radiologists to recognize the diagnosis and rule out eventual associated conditions such as meningiomas, orbital tumors, arachnoid cysts, and fibrous dysplasia. We report the case of PSD diagnosed incidentally in a 51-year-old female patient who presented to the emergency department with confusion.
