RESUMEN
In a case of patient with persistent hypercalcemia after parathyroidectomy, different imaging techniques and particularly 18F-fluorocholine PET/CT are important to localize the adenoma even in a very unusual location.
RESUMEN
Follicular thyroid cancer (FTC) is a less common form of differentiated thyroid cancer. Liver metastasis of differentiated thyroid cancer frequently occurs in the late onset of the metastatic disease, are often unrescetable and noniodine avid, leading to a poor prognosis. A 69-year-old man with a 14-year history of multi-metastatic follicular thyroid cancer was treated iteratively with 131-Iodine allowing to maintain a stable disease. Upon a recent exponential increase of the thyroglobulin, a peritoneal mass and a voluminous hepatic metastasis were discovered, comorbidities and an insufficient future remnant liver function excluded liver surgical resection. The tumour board proposed a resection of the peritoneal mass followed by selective internal radiation therapy of the liver mass. Due to the already impaired liver function, personalized dosimetry allowed a safe treatment delivering low activity to the nontumoral liver followed by a clinical and imaging response of the liver mass at 3 months. At our knowledge, this is the first case of thyroid liver metastasis treated by selective internal radiation therapy.
RESUMEN
OBJECTIVE: To compare contrast-enhanced MR angiography (CE-MRA) and DSA for the follow-up of intracranial aneurysms (IAs) treated with the Woven EndoBridge embolization system DL (WEB DL; Sequent Medical, Aliso Viejo, California, USA). MATERIALS AND METHODS: We retrospectively identified all patients treated with a WEB DL between November 2010 and February 2013 in 2 hospitals. The IA occlusion was graded on follow-up CE-MRA and DSA by 4 independent readers and by 2 readers reaching a consensus, respectively. Interobserver agreement for MRA and intertechnique agreement was evaluated by calculating linear weighted κ. RESULTS: Fifteen patients with 16 IAs were included. Mean delay between MRA and DSA was 2â months (range 0-16â months). Interobserver agreement for MRA was substantial to almost perfect (κ=0.686-0.921; mean κ=0.809). Intertechnique agreement was moderate to substantial (κ=0.579-0.724; mean κ=0.669). Only three out of five inadequately occluded IAs were detected by MRA. CONCLUSIONS: CE-MRA is a useful tool for the follow-up of IAs treated with a WEB DL. However, early follow-up with DSA remains mandatory to detect inadequately occluded IAs.
