BACKGROUND: Although recent data are contradictory, it is still claimed that Pressurized Intra-Peritoneal Aerosol Chemotherapy (PIPAC) would deliver an aerosol which distributes homogeneously throughout the entire abdominal cavity. METHODS: (99m)Tc-Pertechnetat was administered in four postmortem swine using either PIPAC or liquid intra-peritoneal chemotherapy (IPC). The animals were examined by planar scintigraphy and SPECT/CT. Planar distribution images were divided into four regions of interest (ROIs: right/left upper and lower abdominal quadrant)...

Multimodality imaging, including MRI, bone scintigraphy, and FDG PET/CT, was performed to evaluate a 49-year-old man who had right hip and lower limb pain for 4 months because possible malignancy was suspected. All 3 modalities showed obvious Paget disease of the lumbar spine. However, less impressive increased activity was also noted on FDG PET/CT images. Subsequent laboratory tests and pathology examination leads to diagnosis of multiple myeloma. Our case further confirms the notion that it is insufficient to focus on the most obvious and unintentionally overlook the less impressive findings in interpreting nuclear medicine images...

A 76-year-old man who had undergone tricuspid annuloplasty 13 years earlier was admitted to our hospital because of a high fever. Although he was treated with antibiotics for pneumonia, a mild fever persisted. Computed tomography and gallium scintigraphy revealed a mediastinal abscess with an expanded polytetrafluoroethylene (ePTFE) membrane. There were no positive cultures or sternal changes indicating poststernotomy mediastinitis. The membrane was removed by a left parasternal approach without resternotomy, and its total removal was essential for the patient's recovery...

Xiaofei Zhao, Hongming Zhuang
Elevated activity in the lung field on gastroesophageal scintigraphy (milk scan) generally indicates aspiration of the gastric content that has refluxed to the pharynx. An 18-year-old man underwent to gastroesophageal scintigraphy to assess the rate of gastric emptying. Increased activity was noted in the left lower lung field during the image acquisition. Careful analysis of the images showed that this activity was caused by hiatal herniation.

Both pharmacological and invasive treatment of chronic thromboembolic pulmonary hypertension (CTEPH) is now available in Poland and the awareness of the disease among physicians is growing. Thus, the Polish Cardiac Society's Working Group on Pulmonary Circulation in cooperation with independent experts in this field, have launched the statement on algorithm to guide a CTEPH diagnosis in patients with previous acute pulmonary embolism (APE). In Poland, every year this disease affects about 250 patients. CTEPH should be suspected in individuals after APE with dyspnea, despite at least 3 months period of effective anticoagulation, particularly when specified risk factors are present...

Disease with Lewy bodies or dementia with Lewy bodies (DLB), particularly at the prodromal stage, is a complex disease to diagnose because of different clinical beginnings and variable paths in terms of clinical expression. Thus DLB can be entcountered in different input modes: mild cognitive impairment, depression, acute behavioral disorders, confusion and delirium, or sleep disorders. In the aim to better diagnose the disease, should be sought obviously to search for the key symptoms: fluctuations, hallucinations, extra-pyramidal syndrome, and REM sleep behavior disorder...

Chronic elevation of pulmonary microvascular pressure (Pmv) consistently leads to alveolocapillary barrier thickening and reduction in the filtration coefficient. In animal models of chronic heart failure (CHF) the lung remains dry despite hydrostatic forces. As fluid flux is bi-directional, it has been postulated that an increase in alveolar fluid clearance may facilitate the dry lung when Pmv is chronically elevated. In this study we aimed to examine alveolar fluid clearance in ambulatory patients with CHF secondary to left ventricular (LV) systolic dysfunction compared against non-CHF controls...

BACKGROUND: Gastroesophageal reflux disease (GERD) is the most common gastrointestinal disorder of the esophagus. It is a chronic, progressive disorder that presents most typically with heartburn and regurgitation and atypically with chest pain, dysphagia, chronic cough, globus, or sore throat. The mainstay for diagnosis and characterization of the disorder is esophagoduodenoscopy (EGD), high-resolution esophageal manometry, and symptom-associated ambulatory esophageal pH impedance monitoring...

We report a 14-year-old boy with recurrent episodes of headache caused by uncontrolled hypertension. The diagnosis of renovascular hypertension due to Takaysu arteritis (TA) was made based on an increase in erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) and computed tomography (CT) image of bilateral renal artery stenosis was taken. Renal scintigraphy revealed normal perfusion and function of the right kidney and severe reduction of the perfusion and function of the left kidney. Careful drug adjustments significantly improved but did not fully control the blood pressure (BP); further, angioplasty, which showed almost occlusion of the left renal artery opening and the minor narrowing of the right renal artery, failed to regain sufficient BP control...

We report a case with 46-year-old man diagnosed with mitochondrial cardiomyopathy in the dilated phase of hypertrophic cardiomyopathy. Since cardiac magnetic resonance imaging, beta-methyl-p-(123)I-iodophenyl-pentadecanoic myocardial scintigraphy, and positron emission tomography/computed tomography revealed no remarkable findings, we performed electron microscopic examination, which aided in diagnosing mitochondrial cardiomyopathy. Muscle biopsy was also compatible with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes and DNA analysis also concluded it...
