Less frequently, Caduet causes headache (5%). Epidermoid cysts are managed conservatively. Calvarial lesions are frequently identified in radiological studies. Type II cysts have internal septa, slightly higher internal attenuation resulting from dense debris, and small peripheral wheellike daughter cysts that often have lower internal attenuation than the mother cyst [14, 16, 32, 34].

Scalp lesions can be classified as congenital, traumatic, inflammatory, or neoplastic in origin. Cystic Lesions of the Liver. Eventually, this phenotype distribution also occurs in the myelofibrotic spleen, leading to splenic fibrosis and then ineffective hematopoiesis involving megakaryocytes, myeloid cells, fibroblasts, and endothelial cells [54].
