case_images: (a) Post high dose therapy scan with anterior and posterior views showing RAI avid lesions in bilateral adnexal regions. (b and c) Coronal and Axial sections CT images showing heterogeneous soft tissue attenuation with fatty component and calcifications measuring approx. 2.2 cm x 2.7 cm on right side and 2.5 cm x 3.0 cm on left side, suggestive of bilateral teratoma as depicted by arrows

case_images: Posthigh dose therapy scan (PHDTS) with 100 mCi revealed pretherapy scan documented lesions with another two foci of abnormal RAI avid lesions in the bilateral adnexal region [Figure 1a] corresponding to heterogeneous soft-tissue attenuation with fatty component and calcifications measuring 2.2 cm x 2.7 cm on the right side and 2.5 cm x 3.0 cm on the left side on computerized tomography (CT) images - bilateral teratoma [Figure 1b and c].

case_images: (a) Post high dose therapy scan with anterior and posterior views showing RAI avid focus in thyroid bed region and another focus in the pelvic region. (b and c) Axial and coronal sections CT images showing peripherally calcified heterogeneous lesion in uterus favoring uterine leiomyoma as depicted by arrows

case_images: PHDTS with 100 mCi showed pretherapy scan documented lesions along with another focus of radiotracer concentration in the pelvic region [Figure 2a], corresponding to peripherally calcified heterogeneous lesion in the uterus on CT images - with features more in favor of uterine leiomyoma [Figure 2b and c].

case_images: (a) Post high dose therapy scan with anterior and posterior views showing multiple foci of RAI avidity in bilateral lungs and right femur region with focal increased RAI avidity in right periorbital region. (b and c) Axial and sagittal sections CT images showing mucosal thickening in Right maxillary sinus corresponding to sinusitis as depicted by arrows

case_images: PHDTS with 200 mCi revealed multiple foci of RAI avid lesions in soft-tissue thickening in oropharynx bilateral II, III, and IV lymph nodes, in bilateral lungs, left hemipelvis region, and right distal femur region [Figure 3a]. Focal increased radiotracer uptake in the right periorbital region which corresponds to soft-tissue thickening in the right maxillary sinus - Sinusitis on CT images [Figure 3b and c].

case_images: (a) Post high dose therapy scan with anterior and posterior views showing evidence of RAI avid foci in left hemithorax posterior aspect. (b) Post excision and post high dose therapy scan anterior and posterior views showing no evidence of RAI avid foci in the previously documented site in left hemithorax. (c) Histopathological examination slides 4X showing lobules of mature adipocytes with intervening small capillaries - Suggestive of Lipoma

case_images: Biochemical profile: S.TG 8.09 ng/mL, S. anti-TG 18.48 IU/L, TSH 95.05 mIU/L, and PHDTS with 100 mCi showed radioiodine avid focus in left thorax posterior aspect along with pretherapy documented lesions [Figure 4a]. On clinical examination, there is subcutaneous swelling with features more consistent with lipoma, histopathological examination (HPE) after excision turned out to be lipoma [Figure 4c]. Postexcision diagnostic follow-up scan shows no RAI focus in previously documented site in left hemithorax region [Figure 4b].

case_images: (a) Iodine 131 whole body scan anterior and posterior views showing evidence of RAI avid thyroid bed residue with lung, liver and bone metastases. (b) Axial section CT image showing polka dot appearance (arrow) and (c) Coronal section CT image showing corduroy sign (arrow) in D7 vertebra - suggestive of hemangioma

case_images: RAI avid residue, and multiple foci in bilateral lungs, liver, and lytic lesions involving the right scapula, left 3rd rib, D3, D4, and D7 vertebrae [Figure 5a]. RAI focus at D7 vertebra corresponds to vertebral hemangioma on attenuation-corrected CT images [Figure 5b and c].
