This section revolves around the complexity of calcified coronary lesions and their treatment, from specialised balloon technology to atherectomy devices and lithotripsy. The development of a splenic mass represents a dysregulated tumor microenvironment within the spleen as a result of extramedullary hematopoiesis and increased endothelial cell proliferation [55]. Epidermoid cysts are among the rarest type of true cysts and are thought to develop from mesothelial cells entrapped within the spleen during early embryonic development [14, 15]. Swensen et al studied the relationship between the size of a SPN and the chance of malignancy in a cohort at high risk for lung cancer (1). For example, chest X-ray is familiar to everyone. Intracerebral cystic calcified lesions are usually associated with low-grade primary brain tumours, and with infectious diseases; however, the possibility of atypical brain metastases in patients with breast cancer should be considered despite being rare, since prompt diagnosis allows early therapy and better treatment outcomes. In this case, the keratin has calcified. Epidermoid cysts are managed conservatively. The management strategy for angiosarcoma is splenectomy and chemotherapy after diagnosis is confirmed with fine-needle aspiration biopsy. However, calcifications are much less common in these cysts than in pseudocysts [16]. 6C) or, after treatment, secondary to necrosis, hemorrhage, or fibrosis [12].
