We report a very rare case of LAM with malignant lymphoma. A 51-year-old female had medical history of recurrent pneumothorax and nephrectomy for a left renal angiomyolipoma and was diagnosed with LAM by video-assisted thoracoscopic surgery at the age of 30. She presented with left neck mass. Computed tomography and magnetic response imaging showed multiple enlarged cervical lymph nodes. 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) showed abnormal uptake in the mass. We suspected a malignant tumor or extrapulmonary lesion of LAM, and performed surgical biopsy. Pathologically, diffuse large B-cell lymphoma ...

Authors: Skalický T, Skalický A Abstract The presented case report describes primarily an unrecognized liver injury after the resuscitation with cardiac massage due to myocardial infarction. After myocardial revascularization, the hemodynamic instability and anaemia in the patient persisted. The performed CT scan confirmed a liver injury, namely the rupture of liver parenchyma with hemoperitoneum, which had to be treated surgically. It represents a complication of cardiac massage that occurs, though less frequently. Key words: resuscitation, liver trauma. PMID: 31941573 [PubMed - in process]

CONCLUSIONS Authors prefer using autologous bone flaps during cranioplasty. In cases where this method is unavailable, a synthetic bone substitute has to be used. The first medium-term experience with the use of a Cranio-Oss implant made of PEEK showed that it is a suitable alternative to the patient's own bone. No complications associated with this synthetic implant were reported and its use to manage skull defects can be strongly recommended. With respect to legal and accreditationrelated difficulties connected with bone fragments storage and thanks to the continuous cost reduction of synthetic implants will their import...

Abstract PURPOSE: To evaluate liver regeneration after selective ligation of portal vein and hepatic artery by 3D Computed Tomography in an experimental model. METHODS: Sixteen Wistar rats were randomized into four equal groups: Group I- control (sham), Group II- isolated selective ligation of the hepatic artery, Group III- isolated selective ligation of the portal vein and Group IV- combined ligation of portal vein and hepatic artery. Before procedure and five days after a 3D CT Scan was performed to analyze the hypertrophy, weight and function of the remnant liver. RESULTS: The largest regeneration rat...

Objectives Atherosclerotic plaque molecular imaging with 18F-sodium fluoride (NaF) PET with computed tomography (PET-CT) may identify active unstable microcalcification. We sought to explore renal arteries calcification activity in a group of high cardiovascular (CV) risk subjects without manifest CV disease. Methods High CV risk hypertensive individuals from a single centre were prospectively scanned with 18F-NaF-PET-CT in major vascular territories. Renal arterial wall activity was retrospectively analysed and expressed as the ratio between maximum standard uptake value in the lesion and mean blood pool activity in ...

We present a novel computed tomography-based tissue segmentation methodology for determining volume and global uptake of FDG of the thigh muscles and correlate these parameters with age. Materials and methods A total of 71 subjects from a prospective clinical trial (NCT01724749) were included. PET/CT scans were acquired 180 minutes after intravenous injection of FDG. A 3D growing region algorithm with neighborhood Hounsfield unit threshold between one and 150 was used to highlight the muscle. FDG uptake was expressed as the average mean standardized uptake value normalized for lean body mass (average SULmean). Femur vol...

Conclusion Ga-68 DOTATATE PET/CT findings led to a change in the scheduled treatment plan in 90.9% of patients with suspected recurrence. The most frequent change consisted in initiation of PRRT due to disease recurrence or progression or detection of multiple metastases.
