case_images: Neck ultrasound showed a 3.6 cm round hypoechoic nodule posterior to the left inferior thyroid lobe with undefined margins; no signs of infiltration of local tissues were detected.

case_images: Neck ultrasound showed a 3.6 cm round hypoechoic nodule posterior to the left inferior thyroid lobe with undefined margins; Colour Doppler showed increased vascularity in the nodule ( Figure 1 ).
case_images: Dual-phase Tc-99m sestamibi scintigraphy. Early (5 and 30 min.) and delayed (60 and 120 min.) images showed a persistent accumulation of radiopharmaceuticals in the left inferior parathyroid region.

case_images: The same lesion was detected by Technetium-99m MIBI scan, documenting a persistent uptake in the left inferior parathyroid region ( Figure 2 ).
case_images: Intense glucose uptake in the anterior neck region was observed at 18-FDG PET/CT scan (A). The exam also documented a peripheral mild glucose uptake from several abdominal masses (B).

case_images: Furthermore, 18-FDG PET/CT showed mild glucose uptake from abdominal masses, suspicious of inflammatory processes; diffuse glucose uptake from skeletal lesions; and intense homogenous uptake in the anterior neck region, with SUVmax value of 4.8 ( Figure 3 ).
case_images: Consistent reduction of the inhomogeneous abdominal masses, as for physiological evolution of pancreatitis in resolution, documented at CT scan.

case_images: The CT scan also showed a consistent reduction of the inhomogeneous abdominal masses, as for physiological evolution of pancreatitis in resolution ( Figure 4 ).
case_images: X-ray of articular sites, such as wrist (A) and elbow (B) showed a cartilaginous deposit of calcium pyrophosphate, as for chondrocalcinosis.

case_images: Ultrasound articular imaging of hands, wrists, elbows, knees, and ankles showed the presence of calcification in the cartilage around the joints, associated with synovitis; X-ray of the same sites confirmed a cartilaginous deposit of calcium pyrophosphate, as for chondrocalcinosis ( Figure 5 ).
