Fabella is a sesamoid bone, located within the tendon of the lateral head of the gastrocnemius muscle. It may be associated with posterolateral knee pain because of repetitive friction over the posterolateral femoral condyle. We report a case of a 64-year-old woman presenting with right posterolateral knee pain. F-NaF PET-CT demonstrated increased uptake posterior to the right knee joint localizing to a fabella. Standard examination and radiographic imaging excluded other causes for posterolateral knee pain, and the increased activity was considered to be secondary to fabella syndrome...

Malignant tumors account for most sources of ectopic ACTH Cushing syndrome (EA-CS). Early localization of the source and complete removal can be curative and also prevent metastasis. Diagnostic CT is known to perform better than PET/CT (low dose) in characterizing lung pathologies. However, bronchial carcinoids, a common source of EA-CS, may be difficult to detect on chest CT scan especially when it is small and located close to the hilar region. We present a case of EA-CS due to bronchial carcinoid, which was easily seen on Ga DOTANOC PET/CT after a diagnostic chest CT was reported as normal...

A 73-year-old man was referred for F-FDG PET/CT study for staging of biopsy-proven pancreatic adenocarcinoma. The scan demonstrated focal intense FDG uptake in the pancreatic head, localizing the primary tumor. Additional moderate diffuse uptake was seen throughout the pancreas, suggestive of acute pancreatitis. Concurrent diagnostic CT showed diffuse pancreatic hypoenhancement consistent with edema. Serum lipase level was elevated, confirming a diagnosis of acute pancreatitis.

A 69-year-old woman had gradually worsening abdominal discomfort over a year. A pancreatic mass was revealed by abdominal CT. The patient underwent FDG PET/CT for staging, which demonstrated the hypermetabolic pancreatic mass with multiple liver metastases. The lesion was pathologically confirmed as pancreatic adenosquamous carcinoma after biopsy.

A 54-year-old man with a 3-week history of orthostatic headache and acute on chronic subdural hematoma presented with imaging findings suggestive of spontaneous intracranial hypotension. Three myelograms were negative for leak, and nontargeted epidural blood patches did not result in symptom relief. A cerebrospinal fluid leak study using In-DTPA with SPECT/CT demonstrated a focal area of asymmetric activity at the left C2 nerve root. A left C2 root tie-off, targeted epidural blood patch, and Dura seal glue resulted in resolution of patient symptomatology highlighting the importance of fused SPECT/CT images in detection of an occult cerebral spinal fluid leak...

The differentiation of benign and indolent renal masses from aggressive tumor histologies cannot be reliably performed by CT or MRI. Additionally, renal mass biopsy risks complications and has a nondiagnostic rate of 10% to 20%. Tc-MIBI SPECT/CT has been shown to allow for the accurate differentiation of benign renal oncocytomas and hybrid oncocytic/chormophobe tumors from other more aggressive renal tumor types. We present the case of an 84-year-old man with chronic kidney disease and an 11.2-cm renal mass...

Approximately 30 years ago, it has been suggested that chlorhexidine, which is used as antiseptic, can produce Tc colloid complex during Tc-dimercaptosuccinic acid (DMSA) preparation. However, in all cases of liver and spleen uptake in Tc-DMSA scan, it should still be kept in mind because of the introduction of new antiseptic brands with different formulation under various names. Our case is just a sample of this effect, which resulted from application of a new brand of antiseptic by technologists in our center that unintentionally led to low-quality Tc-DMSA scans for a period, and after restrict control of all other confounding factors in the preparation of kit, it was just resolved by changing antiseptic to ethanol...

We have earlier reported the potential of Tm-EDTMP as an alternative cost-effective radiopharmaceutical of SrCl2 for bone pain palliation application. Encouraging results obtained in the radiochemical studies and biological evaluations in animal model have prompted us to initiate the clinical study to evaluate the potential of Tm-EDTMP in human cancer patients. The serial scintigraphic images represent the whole-body scans of a patient (68 years old woman) with skeletal metastases of carcinoma of the breast origin recorded after administering 370 MBq (10 mCi) of Tm-EDTMP at different post-administration time points along with the pre-therapy images recorded with Tc-MDP in the same patient...

Fibrous dysplasia of the bone is a developmental benign skeletal disorder characterized by replacement of normal bone and normal bone marrow with abnormal fibro-osseous tissue. We report on a case of a biopsy-proven fibrous dysplasia lesion in the left temporal bone, with intensely increased activity (SUVmax, 56.7) on Ga-DOTATATE PET/CT. The presented data indicate cell surface overexpression of somatostatin receptors by fibrous dysplastic cells and highlight the need of cautious management of Ga-DOTATATE-avid bone lesions, which could mimic malignancy especially in patients with history of neuroendocrine tumors...

PURPOSE: Salivary gland carcinoma (SGC) is rare tumor with various histological type and metastatic potential. Pretreatment detection of metastases can contribute to planning the appropriate treatment of SGC. Therefore, the present study evaluated the utility of F-FDG PET/CT versus contrast-enhanced CT for detection of metastases and prediction of outcomes in SGC patients. METHODS: Sixty-seven consecutive SGC patients who were prospectively evaluated by F-FDG PET/CT and contrast-enhanced CT and subsequently underwent surgery with or without postoperative radiotherapy/chemoradiotherapy were included...

PURPOSE: The aim of this study was to assess therapeutic response to breast cancer neoadjuvant chemotherapy (NAC) by F-FDG positron emission mammography (PEM) compared with that to whole-body F-FDG PET (WBPET). METHODS: Twenty patients underwent WBPET and PEM 3 times: the first time was before NAC, the second time was after 2 courses of NAC, and the third time was after all courses of NAC. A pathological complete response (pCR) was defined as no evidence of residual invasive cancer with or without ductal carcinoma in situ...

A 70-year-old man with suspected prostate cancer was referred for Ga-PSMA-HBED-CC PET/CT (short PSMA PET/CT) for staging of tumor extent. Apart from vivid tracer uptake in the prostate gland and osseous metastasis, PSMA PET/CT revealed a large soft tissue mass with calcifications in the left upper abdomen showing intense tracer uptake. Histologic examination revealed the mass to be a gastrointestinal stromal tumor.

We describe 2 cases of Ga-PSMA PET/CT in prostate cancer patients. Both cases demonstrated symmetrical bilateral involvement of mediastinal and hilar lymph nodes besides findings in relation with prostatic disease. In both cases, endobronchial ultrasound-guided biopsy showed that the involvement of the thoracic lymph nodes was caused by nonnecrotic granulomas compatible with sarcoidosis. The cases demonstrated that increased Ga-PSMA uptake can be seen in lymph nodes with active sarcoidosis, with images mimicking those well known from FDG PET/CT...

A 25-year-old woman with intractable seizures underwent FDG PET/MRI for seizure focus localization. MRI demonstrated bilateral carpetlike nodular subependymal gray matter and asymmetrical focal dilatation in the right temporal horn. PET/MRI showed increased FDG within subependymal gray matter with significant hypometabolism in right anterior temporal lobe. EEG and ictal semiology confirmed the right temporal seizure origin. This case highlights the importance of identification of gray matter heterotopia on FDG PET/MRI...

Hepatobiliary scintigraphy is a widely used functional imaging modality for diagnosis of a variety of liver diseases, as well as for detecting biliary tract abnormalities. Neonates or infants with persistent jaundice beyond the physiological period are usually evaluated with hepatobiliary scintigraphy. The authors present a 5-month-old girl with neonatal jaundice, ascites, and umbilical and bilateral inguinal hernias in whom spontaneous rupture of the biliary duct resulted in intraperitoneal bile leak with passage of tracer into bilateral inguinal hernial sacs...
