Intravenous leiomyomatosis (IVL) of the uterus is a rare neoplasm which usually occurs after hysterectomy. Due to its rarity and non-specific clinical manifestations, IVL is commonly misdiagnosed as malignant thrombus or thrombosis and treated inappropriately. Herein, we report an unusual case of a 51 years old woman with IVL without hysterectomy or abdominal manifestations. The IVL was detected in the right atrium. This case highlights the usefulness of (18)F-FDG PET/CT in the diagnosis of IVL.

Multiple pulmonary hamartomas (PH) occur rarely, are mostly seen in females, and are usually leiomyomatous hamartomas. Here, we report an extremely rare case of a 30 years old male patient diagnosed as multiple pulmonary chondromatous hamartomas. He was admitted on May 2015 to our hospital for a 3 months history of cough. Multiple nodules in the right lung were detected on chest X-rays during a routine checkup 9 months ago and in a subsequent chest computed tomography (CT). However, he abandoned medical follow-up because he was asymptomatic...

Coronary artery fistula (CAF) is a rare anomaly that originates from the coronary artery and drains into the cardiac chamber or the adjacent vasculature. We report a case of CAF in a 77 years old woman with dyspnea on exertion. Using coronary angiography and cardiac multidetector computed tomography, this patient was diagnosed with CAF draining into the left bronchial arteries. First-pass radionuclide angiography (FPRNA) showed early pulmonary recirculation through a left to right shunt. The pulmonary to systemic blood flow ratio was 1...

We report the incidental diagnosis of acute asymptomatic appendicitis on a fluorine-18-fluorodeoxyglucose positron emission tomography with computed tomography ((18)F-FDG PET/CT) performed for staging of a non small cell lung carcinoma. The patient was asymptomatic and laboratory tests were normal. The case illustrates: a) the possibility to diagnose appendicitis on (18)F-FDG PET/CT and b) the possibility of silent acute appendicitis, although this is a rare occurrence.

UNLABELLED: A 9 years old boy presented to our hospital complaining of night sweat and weight loss (5kg) for 3 months followed by cough, nausea, vomiting and malaise for two weeks. During that time he was found to have continuous hypertension. The clinical, electrocardiogram (ECG), renal scintigraphy and biologic findings suggested multi organ-failure syndrome. Computed tomography (CT) and ultrasound revealed a right adrenal tumor. Vanillymandelic acid (VMA) in the 24 hours urine sample was not elevated...

OBJECTIVE: Small intestine bacterial overgrowth (SIBO) may be a pathogenetic factor for irritable bowel syndrome (IBS). This syndrome cannot be explained by structural abnormalities and has no specific diagnostic laboratory tests or biomarkers. We studied quantitatively and semi-quantitatively, using lactulose hydrogen breath test (LHBT), small intestinal transit time (SITT) (99m)technetium-diethylene triamine pentaacetic acid ((99m)Tc-DTPA) in order to examine the mobility of small intestine as an indication of bacterial overgrowth in patients...

In multimodality imaging, CT-derived transmission maps are used for attenuation correction (AC) of SPET or PET data. Regarding SPET myocardial perfusion imaging (MPI), however, the bene����t of CT-based AC (CT-AC) has been questioned. Although most attenuation-related artifacts are removed by this technique, new false defects may appear while some true perfusion abnormalities may be masked. The merits and the drawbacks of CT-AC in MPI SPET are reviewed and discussed in this editorial. In conclusion, CT-AC is most helpful in men, overweight in particular, and in those with low or low to intermediate pre-test probability of coronary artery disease (CAD)...

Neuroendocrine tumors (neuroendocrine tumors-NET) are a heterogeneous group of neoplasms with a common embryological origin and diverse biological behavior, derived from cells of the neuroendocrine system, the system APUD (amine precursor uptake and decarboxylation). They are characterized by overexpression of all five somatostatin receptors (SSTR1-SSTR5), particularly type 2 (SST2). Surgical resection of the tumor is the treatment option, with a possibility of complete remission in patients with limited disease...
