Regional ventilation/perfusion mismatch pattern in patient with Swyer James (MacLeod's) syndrome

Swyer James (McLeod's) syndrome (SJMS) is an uncommon disease, which occurs as a result of childhood bronchiolitis obliterans. Patients may not be diagnosed until later in their life. A 46-year-old man underwent ventilation/perfusion scintigraphy for acute onset of dyspnea. The scan showed markedly diminished ventilation and perfusion unilaterally on the right middle and inferior lobes. However, mismatched ventilation-perfusion pattern was shown on the upper right lobe, which was consistent with pulmonary embolism. Unilaterally matched ventilation/perfusion defect can see in SJMS in lung scintigraphy; however, when pulmoner embolism may accompany, scintigraphy should be carefully examined

A rare case of solitary subcutaneous scalp metastasis from follicular thyroid carcinoma revealed with positron emission tomography/computed tomography: A case report and review

Differentiated thyroid cancer frequently metastasizes to regional cervical lymph nodes and in advanced cases metastases can be seen in the lungs and skeleton. Metastases to the skin or subcutaneous tissue are rare. Here we present a 49-year-old female patient with solitary scalp metastasis from follicular thyroid carcinoma FTC which was revealed with positron emission tomography (PET)/computed tomography (CT) imaging. PET showed flourodeoxiglucose avid lesion in the left vertex scalp. Scalp lesion was removed totally and histopathological examination revealed well-differentiated thyroid cancer metastasis

Comparison of Tc-99m-HYNIC-TOC and HYNIC-TATE Octreotide Scintigraphy With FDG PET and Tc-99m-MIBI in Local Recurrent or Distant Metastatic Thyroid Cancers

Aim: There have been various studies for early diagnosis of local recurrent or distant metastatic thyroid cancers. The aim of this study is to evaluate the clinical utility of Tc-99m-HYNIC-TOC and Tc-99m-HYNIC-TATE, octreotide derivatives, to detect recurrences or distant metastases in I-131-negative thyroglobulin positive thyroid cancer patients and to compare the lesions with FDG PET and Tc-99m-MIBI studies in the same patient group
