ABSTRACT
Lipoblastoma is a benign soft tissue tumor that originates from embryonic white fat. Lipoblastoma presents as a slow-growing mass that commonly occurs in the extremities of young children. Histological examination remains the gold standard in confirming lipoblastoma; however, radiology examination can help identify and evaluate the extent and characterization of the mass prior to the excision. Here, we report a 7-year-old male patient who presented with a painless mass in the right popliteal extending to the proximal cruris areas, and the imaging modalities suggested the presence of fat within the mass. The patient then underwent complete excision, and histopathology examination revealed lipoblastoma. This study highlights the possibility of lipoblastoma in older children and the role of imaging examinations in the diagnosis.
ABSTRACT
Neurocysticercosis is a serious underreported tropical disease caused by the ingestion of Taenia solium eggs through fecal-oral contact. The infection can affect any organ but frequently affects the central nervous system, eyes, and muscles, and is able to remain dormant for years in the brain. Medical imaging is crucial in making the diagnosis of neurocysticercosis as there are no identifiable clinical symptoms of the condition. In this case, we present a 71-year-old man with neurocysticercosis diagnosed by CT scan, MRI and MR spectroscopy. Calcified nodules were found with surrounding vasogenic edema on CT scan. Magnetic Resonance Imaging (MRI) showed multiple lesions that were hypointense on T1-weighted image, hyperintense rim on T2-weighted image, with ring enhancement on postcontrast scanning characterizing granular nodular stage and multiple lesions that were hypointense on T1-weighted image and no signal on T2-weighted image characterizing nodular calcified stage of the disease. MR Spectroscopy showed decreased levels of choline, creatine, NAA, NAA/Cr and Cho/Cr ratio with increased levels of lactate and lipid.
