AIM: Percutaneous transthoracic needle biopsy (PTNB), an alternative to bronchoscopic confirmation of lung lesions, is today being associated with a risk of pneumothorax and hemorrhage. Further, there are no data on the possible risk of malignant disease spreading to the pleura at the site of the PTNB. Previous studies have dealt with this risk in stage I non-small cell lung cancer only. The aim of this study was thus to assess the risk of pleural recurrence for all types of lung lesions. Secondary objectives included assessment of diagnostic yield and safety with respect to the incidence of pneumothorax and hemorrhage. METHODS: Clinical data of all patients from the University Hospital in Pilsen who had undergone PTNB of lung lesions between 1.1.2018 and 31.12.2022 were included in this retrospective study. RESULTS: Following PTNB, ipsilateral pleural effusion occurred in 4.8% of patients without prior pleural infiltration. The effusion was confirmed as malignant in one patient (0.7%). Diagnostic yield of the method was 86.6%. We recorded pneumothorax or hemorrhage in the lung parenchyma or pleural space requiring medical intervention in 3.4% and 1.1% of patients, respectively. CONCLUSION: In our study, percutaneous transthoracic needle biopsy of lung lesions showed high sensitivity and low degree of acute complications requiring an invasive solution. The risk of pleural recurrence after a biopsy was very low. Consequently, we continue to consider this method to be an alternative to bronchoscopy biopsies.

The topic of the diagnosis of phaeochromocytomas remains highly relevant because of advances in laboratory diagnostics, genetics, and therapeutic options and also the development of imaging methods. Computed tomography still represents an essential tool in clinical practice, especially in incidentally discovered adrenal masses; it allows morphological evaluation, including size, shape, necrosis, and unenhanced attenuation. More advanced post-processing tools to analyse digital images, such as texture analysis and radiomics, are currently being studied. Radiomic features utilise digital image pixels to calculate parameters and relations undetectable by the human eye. On the other hand, the amount of radiomic data requires massive computer capacity. Radiomics, together with machine learning and artificial intelligence in general, has the potential to improve not only the differential diagnosis but also the prediction of complications and therapy outcomes of phaeochromocytomas in the future. Currently, the potential of radiomics and machine learning does not match expectations and awaits its fulfilment.

Infekční endokarditida představuje velmi závažné onemocnění s možnými kardiálními i extrakardiálními vzdálenými komplikacemi. Výpočetní tomografie i magnetická rezonance hrají v současnosti zásadní roli v diagnostice i sledování komplikací či efektu terapie a jsou součástí doporučení Evropské i Americké kardiologické společnosti pro tuto problematiku. Článek obsahuje základní teoretické informace o infekční endokarditidě od rizikových faktorů, patogenů, přes klinický obraz až po diagnostiku. Dále je uvedeno šest kazuistik s typickou anamnézou a ilustrativním nálezem na vyšetřeních na výpočetní tomografii a jeden z případů představuje extrakardiální intrakraniální komplikace na magnetické rezonanci.
Infective endocarditis is a very serious disease with possible cardiac and extracardiac distant complications. Computed tomography and magnetic resonance imaging currently play an essential role in diagnosis and monitoring of complications or the effect of therapy, and are part of the recommendations of the European and American Society of Cardiology for this issue. The article contains basic theoretical information about infective endocarditis, from risk factors, pathogens, through the clinical picture to diagnostics. Furthermore, six case reports with a typical history and illustrative findings on computed tomography examinations are presented, and one of the cases presents extracardiac intracranial complications on magnetic resonance imaging.
BACKGROUND: Percutaneous rhizotomy of the Gasserian ganglion is a well-established intervention for patients suffering from refractory trigeminal pain, not amenable to pharmacological management or microvascular decompression. Traditionally conducted under fluoroscopic guidance using Hartel's technique, this study investigates a modified approach employing low-dose CT guidance to achieve maximal procedural precision and safety with the emphasis on minimizing radiation exposure. METHODS: A retrospective analysis of patients undergoing percutaneous rhizotomy of the Gasserian ganglion at our institution was undertaken. Procedures were divided into fluoroscopy and CT-guided foramen ovale (FO) cannulation cohorts. Radiation doses were assessed, excluding cases with incomplete data. The study included 32 procedures in the fluoroscopy group and 30 in the CT group. RESULTS: In the CT-guided group, the median effective dose was 0.21 mSv. The median number of CT scans per procedure was 4.5, and the median procedure time was 15 min. Successful FO cannulation was achieved in all 30 procedures (100%). In the fluoroscopy group, the median effective dose was 0.022 mSv, and the median procedure time was 15 min. Cannulation of FO was successful in 31 of 32 procedures (96.9%). The only complications in the CT-guided group were three minor cheek hematomas. Immediate pain relief in the CT-guided group was reported in 25 of 30 procedures (83.3%), 22 of 30 (73.3%) provided relief at one month, and 10 of 18 (55.6%) procedures resulting in pain relief at one month continued to provide relief after two years. CONCLUSION: Low-dose CT-guided percutaneous rhizotomy conducted in the radiology suite carries negligible radiation exposure for patients and eliminates it for personnel. This method is fast, simple, precise, and carries a very low risk of complications.

Ročně v České republice diagnostikujeme kolem 6 000 nových případů karcinomu plic. Mutace receptoru 2 pro lidský epidermální růstový faktor (human epidermal growth factor receptor 2, HER2) patří mezi vzácné mutace, které se vyskytují cca u 1-4 % nemocných s NSCLC. V případě prokázané mutace HER2 je možné používat léčebně přípravek trastuzumab deruxtekan. Trastuzumab deruxtekan je konjugát protilátky a léku, který kombinuje humanizovanou monoklonální protilátku trastuzumab s inhibitorem topoizomerázy I deruxtekanem. Tento lék se váže na HER2 na nádorových buňkách. Cytostatikum deruxtekan je společně s HER2 internalizován do nádorové buňky, kde způsobí její destrukci. Kazuistika pacientky léčené trastuzumab deruxtekanem dokládá význam plošného použití sekvenování příští generace v indikovaných případech, zejména u nekuřáků s neskvamózní histologií. Dále ukazuje na nutnost správného čtení výsledků genetického testování a zaznamenávaní výsledků do dokumentace nemocného, aby se informace o přítomné řídicí mutaci v průběhu léčby neztratila.
Around 6,000 new cases of lung cancer are diagnosed annually in the Czech Republic. Human epidermal growth factor receptor 2 (HER2) mutations are rare mutations that occur in approximately 1-4% of patients with NSCLC. In the case of a proven HER2 mutation, it is possible to use the drug trastuzumab deruxtecan in the treatment. Trastuzumab deruxtecan is an antibody-drug conjugate that combines the humanized monoclonal antibody trastuzumab with the topoisomerase I inhibitor deruxtecan. This drug binds to HER2 receptors on tumor cells. The cytostatic drug deruxtecan, together with the HER2 receptor, is internalized into the tumor cell, where it causes its destruction. The case report of a patient treated with trastuzumab deruxtecan demonstrates the importance of widespread use of next generation sequencing in indicated cases, especially in non-smokers with non-squamous histology. It also points to the necessity of correct reading of the genetic testing results and recording the results in the patient's documentation so that information about the present control mutation is not lost during the treatment.

INTRODUCTION: Combined immuno-oncology (IO) regimens are the cornerstone of the current front-line systemic therapy for metastatic renal cell carcinoma (mRCC). Despite the fact that combined IO regimens show high efficacy, they are often accompanied by a wide spectrum of immune-related adverse effects (irAEs). CASE PRESENTATION: We describe a case of rare irAEs manifested as giant cell temporal arteritis (GCA) followed by severe encephalopathy occurring after continuing immunotherapy in a 66-year-old man with mRCC receiving a combination of ipilimumab and nivolumab in the first line of systemic therapy. GCA occurred 4 months after the initiation of IO and responded promptly to the low-dose prednisone therapy. Four months after the continuation of nivolumab maintenance, the patient was hospitalized due to severe irAE encephalopathy which presented as psycho-behavioral abnormalities and progressive cognitive decline. He was treated with high-dose methylprednisolone which led to complete resolution of the symptoms and IO was permanently discontinued. The patient achieved a durable partial response. CONCLUSION: Both GCA and the subsequent encephalopathy in our patient responded well to the corticosteroid therapy, leading to the complete resolution of the symptoms and the patient achieved a durable partial response. Although the risk of severe neurologic irAEs affecting the central nervous system induced by IO re-administration, following previous discontinuation due to irAE, is not well-defined because of their rarity, this case highlights the need for caution, particularly in cases with a history of previous irAE-associated GCA.
