Although patients presenting with scalp masses are frequently seen in daily practice, differentiation of scalp lesions is often challenging for radiologists who are not familiar with the imaging of cutaneous lesions. Pseudocysts occur as a result of prior trauma, pancreatitis, infection, or iatrogenic causes [12]. Malignant scalp tumors are uncommon; however, they carry a potential risk of delayed detection, resulting in poorer outcomes.

The cartilaginous matrix can only be recognised in conventional radiology and the CT-scan by the presence of calcifications. They are most often found on the scalp. Imaging may show a solitary mass, multiple splenic masses, or diffuse splenic involvement with splenomegaly. Chemotherapy is required because of the high proportion of cases with metastatic disease, and splenectomy is also required due to the high risk of rupture [50]. True epithelial cysts form during development with outer cuboidal epithelium and inner endothelium and result from infolding of peritoneal mesothelium within the spleen [13]. Types of calcification. When compared with pseudocysts, which are the primary differential diagnostic consideration for these lesions, true epithelial cysts are more likely to have internal enhancing septations but are less likely to have wall calcifications [14].

Scalp lesions can be classified as congenital, traumatic, inflammatory, or neoplastic in origin. Neuroimaging is especially useful in the diagnosis of neurocysticercosis since it permits visualization of the parasite stage, as well as the number and localization of lesions 72. An understanding of the scalp's anatomy is essential for topographic characterization of a lesion as the first step for a differential diagnosis; not only the imaging appearance, but also the lesion's location, the clinical history, and the patient's age should be considered when evaluating a mass of the scalp.
