Radioiodine scan revealing a primary lung adenocarcinoma in a patient with differentiated thyroid carcinoma

The radioiodine scan is a non-invasive imaging modality that allows for the visualization of functional thyroid tissue, as well as the detection of thyroid cancer remnants and metastases. However, it is important to note that radioiodine uptake is not exclusive to thyroid tissue and can lead to false-positive results if unexpected uptake occurs in non-thyroidal tissue. Herein, we present a case of a patient diagnosed with thyroid carcinoma, whose radioiodine scan demonstrated increased uptake in the thorax, corresponding to a lung carcinoma

Xanthoma of Bone: A Case Report

Bone xanthoma is a rare disease due to the presence of cholesterol deposits in the bone. We report a case of a 56-year-old patient who was hospitalized in orthopedic department for fracture on the left humerus. Histological examination of bone biopsy performed at this site has objectified cholesterol deposits. Laboratory tests showed hypercholesterolemia with hypertriglyceridemia. The diagnosis of bone xanthoma was selected. The fracture was treated surgically. An initial bone scan revealed bone lesions localized especially at the humerus and femur. The patient was put under fenofibrate and statins. The evolution was marked by gradual regression of lesions in bone scans of control
