Cystic parathyroid adenoma: Primary hyperparathyroidism without Tc-MIBI uptake.

Cystic parathyroid adenoma is a rare disease (<0.01% of all cervical masses) that associates primary hyperparathyroidism in 9% of cases. Parathyroid scintigraphy is essential for its diagnosis with uncommon false negative results.

[Sarcoidosis of bone. Findings in the Gallium citrate examination].

Sarcoidosis of bone lesions are rare, with an overall incidence of 3-9% of the cases. When they do occur, they are more frequent in the small bones of hands and feet than in long bones, spine or skull. We report a case of a male patient with sarcoidosis with multiple enlarged lymph nodes, skin and bone lesions, and the scintigraphic findings.

[The clinical relevance of FDG-PET imaging in severe traumatic brain injuries].

Aim: To evaluate the usefulness of positron emission tomography (PET) as a predictor of long-term disability after a severe traumatic brain injury (TBI).

Patients And Methods: Fifty-six patients who had sustained a severe TBI were assessed with a broad battery of cognitive and functional scales at baseline and 6-months after inclusion in a multidisciplinary rehabilitation program. All patients underwent a FDG-PET at baseline.

[Scintigraphy with labelled leukocytes in acute pancreatitis. Preliminary results].

This study aims to evaluate the contribution of the 99mTc-HMPAO labelled leukocyte in the prognostic assessment of patients with acute pancreatitis. We have compared the usual methods of prognostic evaluation (computed tomography CT and the Ranson clinical score scale) with the scintigraphic findings in 23 consecutive patients with a clinical diagnosis of mild or severe acute pancreatitis. All 6 patients with severe pancreatitis showed an uptake which was mostly mild.
