Myeloid Sarcoma That Infiltrated a Preexisting Sebaceous Lymphadenoma in the Parotid Gland: Diagnostic Challenges and Literature Review

Figure 1

(a, b) A CT scan demonstrated a nodular, isodense, and necrotic mass in the left parotid gland and multiple homogenous density, necrotic, and enlarged lymph nodes in the left lateral neck. (a) Postcontrast axial CT image and (b) coronal image. (c–f) MRI of the parotid gland and neck revealed a lobulated necrotic mass that involved the superficial and deep lobes of the left parotid gland and multiple homogenous densities with necrotic enlarged lymph nodes in the left lateral neck. Indeterminate enlarged lymph nodes were observed on the right lateral neck. (c) T2-weighted axial image, (d) T1-weighted axial image, (e) postcontrast T1-weighted axial image, and (f) postcontrast T1-weighted coronal image.
