RESUMO

OBJECTIVES: CT findings of COVID-19 look similar to other atypical and viral (non-COVID-19) pneumonia diseases. This study proposes a clinical computer-aided diagnosis (CAD) system using CT features to automatically discriminate COVID-19 from non-COVID-19 pneumonia patients. METHODS: Overall, 612 patients (306 COVID-19 and 306 non-COVID-19 pneumonia) were recruited. Twenty radiological features were extracted from CT images to evaluate the pattern, location, and distribution of lesions of patients in both groups. All significant CT features were fed in five classifiers namely decision tree, K-nearest neighbor, naïve Bayes, support vector machine, and ensemble to evaluate the best performing CAD system in classifying COVID-19 and non-COVID-19 cases. RESULTS: Location and distribution pattern of involvement, number of the lesion, ground-glass opacity (GGO) and crazy-paving, consolidation, reticular, bronchial wall thickening, nodule, air bronchogram, cavity, pleural effusion, pleural thickening, and lymphadenopathy are the significant features to classify COVID-19 from non-COVID-19 groups. Our proposed CAD system obtained the sensitivity, specificity, and accuracy of 0.965, 93.54%, 90.32%, and 91.94%, respectively, using ensemble (COVIDiag) classifier. CONCLUSIONS: This study proposed a COVIDiag model obtained promising results using CT radiological routine features. It can be considered an adjunct tool by the radiologists during the current COVID-19 pandemic to make an accurate diagnosis. KEY POINTS: • Location and distribution of involvement, number of lesions, GGO and crazy-paving, consolidation, reticular, bronchial wall thickening, nodule, air bronchogram, cavity, pleural effusion, pleural thickening, and lymphadenopathy are the significant features between COVID-19 from non-COVID-19 groups. • The proposed CAD system, COVIDiag, could diagnose COVID-19 pneumonia cases with an AUC of 0.965 (sensitivity = 93.54%; specificity = 90.32%; and accuracy = 91.94%). • The AUC, sensitivity, specificity, and accuracy obtained by radiologist diagnosis are 0.879, 87.10%, 88.71%, and 87.90%, respectively.

RESUMO

RATIONALE: Dasatinib associated lymphadenopathy (DAL) is a rare adverse event in chronic myeloid leukemia patients (CML). A case of voluminous lymphadenopathy in the context of DAL is presented. PATIENT CONCERNS: A 40-year-old male patient was diagnosed with BCR-ABL1 positive chronic stage CML 2 years ago and achieved complete molecular response on nilotinib, which was switched to dasatinib due to nilotinib intolerance. After 5 months on dasatinib, the patient presented with a large mass in the axillary region. DIAGNOSIS: Common infectious and autoimmune etiologies of lymphadenopathy were ruled out. The positron emission tomography/computed tomography (PET/CT) demonstrated a hypermetabolic lymphadenopathy highly suspicious of lymphoma. The subsequent biopsy excluded lymphoma or extramedullary blastic transformation of CML and revealed reactive lymphadenopathy with mixed (cortical and paracortical) pattern. Clinical history and clinicopathological correlation suggested the diagnosis of DAL. INTERVENTION: Dasatinib was discontinued and the patient remained in close follow-up. TKI treatment with nilotinib was reinitiated. OUTCOMES: Lymphadenopathy resolved clinically at 4 weeks and normalization of PET/CT findings was documented at 9 weeks after cessation of the drug. TKI treatment with nilotinib was reinitiated with good tolerance. LESSONS: DAL may present with voluminous lymphadenopathy consistent with malignancy in clinical and imaging workup. We describe the spectrum of lesions associated with DAL and identify common features with drug-induced lymphadenopathy.

RESUMO

Since asymptomatic infections as "covert transmitter", and some patients can progress rapidly in the short term, it is essential to pay attention to the diagnosis and surveillance of asymptomatic patients with SARS-COV2 infection. CT scan has great value in screening and detecting patients with COVID-19 pneumonia, especially in the highly suspected or probable asymptomatic cases with negative RT-PCR for SARS-COV2. This study aimed to detect incidentally COVID-19 pneumonia on medical imaging for patients consulting for other reasons.

RESUMO

BACKGROUND: Endobronchial Ultrasound (EBUS) guided Transbronchial needle aspiration (TBNA) offers a minimally invasive diagnostic tool for mediastinal lymphadenopathy (ML). This study is done with the objective to determine the diagnostic utility of EBUS TBNA for ML in cancer and non-cancer patients. METHODS: This cross-sectional study, in which data was collected retrospectively included TBNA cytopathology and microbiology results of all patients who underwent EBUS at Shaukat Khanum Memorial Cancer Hospital and Research Center, Lahore between July 2013 until July 2018. They were analysed to determine sensitivity and specificity of EBUS. RESULTS: Total 609 patients, comprising 362 (59%) male and 470 (77%) cancer patients were included. Mean age was 52±18 years. TBNA cytology was malignant in 118 (25%) cancer and 20 (14%) non-cancer patients. Percentage malignant ML was highest in small cell lung cancer (93%) among thoracic and renal cell carcinoma (35%) among extra thoracic cancers. Only 27% cancer patients with flourodeoxyglucose-18 avid ML had malignant cytology. Sarcoidosis was diagnosed in 115 (19%) patients (sensitivity 91%, specificity 97%) while tuberculosis in 76 (12%) (Sensitivity 87% and specificity 98%). Endobronchial Ultrasound changed management in 76% cancer patients via multidisciplinary meetings with no reported complications and estimated sensitivity and specificity of 98% and 100% respectively. CONCLUSIONS: Endobronchial Ultrasound is an accurate diagnostic tool for ML and can facilitate multidisciplinary cancer care.

RESUMO

BACKGROUND: As the outbreak of coronavirus disease 2019 (COVID-19) has progressed, computed tomography has emerged as an integral part of the diagnosis alongside reverse transcriptase-polymerase chain reaction assays. Frequently encountered imaging findings include peripheral airspace consolidations; bilateral ground-glass opacities; and, less commonly, cavitation. Hilar lymphadenopathy is a rarely reported finding in the setting of COVID-19. CASE PRESENTATION: A 73-year-old Caucasian woman presented to our hospital with fever and fatigue. She had a maximum body temperature of 102.3 °F with lymphopenia and thrombocytopenia. She was diagnosed with severe acute respiratory syndrome coronavirus 2 infection on the basis of a positive result from a reverse transcriptase-polymerase chain reaction of a nasopharyngeal swab sample. Contrast-enhanced chest computed tomography revealed multifocal, subpleural ground-glass opacities with nodular consolidations bilaterally. Computed tomography also demonstrated atypical bilateral hilar lymphadenopathy, a rarely reported imaging feature of COVID-19. Chest computed tomography 1 month before the presentation did not show focal consolidations or lymphadenopathy. This indicated that the findings were due to the patient's severe acute respiratory syndrome coronavirus 2 infection. She received 5 days of oral hydroxychloroquine and experienced resolution of her symptoms. CONCLUSION: Chest computed tomography has been used extensively to diagnose and characterize the distinguishing radiological findings associated with viral pneumonia. It has emerged as an integral part of the diagnosis of COVID-19 alongside reverse transcriptase-polymerase chain reaction assays. Clinicians must be aware of uncommon clinical and radiological findings in order to diagnose this entity. Hilar lymphadenopathy is commonly seen with fungal infections, mycobacterial infections, and sarcoidosis. An extensive literature review found that bilateral hilar lymphadenopathy has not been reported in the setting of COVID-19. More data are needed to establish the clinical impact of this novel finding.

RESUMO

Los implantes mamarios se asocian a complicaciones frecuentes ampliamente conocidas y estudiadas como la rotura y la contractura capsular. Sin embargo, debido al número cada vez mayor de pacientes portadoras de implantes mamarios, podemos encontrarnos con patología más infrecuente como la presencia de seroma o infección tardía, adenopatías en la cadena mamaria interna, granulomas en la cápsula del implante -que en algunos casos pueden extenderse más allá de la cápsula fibrosa-, tumores desmoides asociados a los implantes y el linfoma anaplásico de células grandes asociado a implantes mamarios. El objetivo de este artículo es revisar las principales complicaciones infrecuentes asociadas a los implantes mamarios y sus hallazgos radiológicos en las diferentes técnicas. Es importante un correcto manejo de esta patología, principalmente del seroma tardío, para diagnosticar precozmente el linfoma anaplásico de células grandes por su mayor transcendencia


Breast implants are associated with well-known common complications that have been widely studied, such as rupture and capsular contraction. However, the increasingly growing number of patients with breast implants has led to the increased likelihood of coming across less common complications; these include seromas or late infection; adenopathies in the internal mammary chain; granulomas in the capsule of the implant, which in some cases can extend beyond the fibrous capsule; desmoid tumors associated with the implants; and breast implant-associated large cell anaplastic lymphoma. This article aims to review the main uncommon complications associated with breast implants and to describe and illustrate their findings in different imaging techniques. Proper management of these complications is important; this is especially true of late seroma and the diagnosis of breast implant-associated large cell anaplastic lymphoma for their repercussions

RESUMO

The purpose of this study was to evaluate radiographs for the detection of sublumbar lymph node (SLN) enlargement. Ultrasound was used to determine SLN size. Twenty-two dogs with anal gland adenocarcinoma or lymphoma were prospectively included, with 16/22 having SLN enlargement on ultrasound. Twenty-one dogs without enlargement were retrospectively included as controls. Three blinded observers evaluated 43 right lateral abdominal radiographs for the presence of SLN enlargement. Sensitivity and specificity of radiographs for the detection of SLN enlargement were 81%/70%, 94%/81%, and 75%/100% for a general practitioner, imaging resident, and radiologist, respectively. Ventral displacement of the colon, a soft tissue opacity in the caudal retroperitoneal space and loss of conspicuity of the ventral margin of the iliopsoas muscle were radiographic findings significantly associated with identification (P-values < 0.05). Markedly enlarged SLNs (> 21.5 mm) were consistently detected radiographically by observers with specialist imaging training. Key clinical message: Radiographic visualization should raise suspicion of neoplastic infiltration of SLN but lack of visualization does not exclude mild to moderate enlargement. Additional imaging such as ultrasound or computed tomography remains important to confirm or exclude sublumbar lymphadenopathy.

RESUMO

A 38-year-old emergency medical service Bell 214 male pilot with a dry cough, fever, anorexia, fatigue, and sweating for the past 3 days; an oral temperature of 38°C; blood pressure of 105/65 mm Hg; heart rate of 94 beats/min; respiratory rate of 21 breaths/min; and pulse oximetry of 93% on room air was suspicious for coronavirus disease 2019. Surprisingly, reverse transcription polymerase chain reaction was negative, but bilateral hilar adenopathy was reported in his chest radiography as a new challenge. The pathologic report of the adenopathy biopsy was noncaseating sarcoid-type granulomas. Serologic tests showed a serum angiotensin-converting enzyme level of 58 nmol/mL/min. The bronchoalveolar lavage fluid CD4/CD8 ratio was 3.68. The bronchoalveolar lavage findings provided an accurate sarcoidosis diagnosis, and a high-resolution computed tomographic scan revealed stage 1 pulmonary involvement. Because of the pulmonary involvement, clinical manifestations, use of inhaled fluticasone, and need for longer and accurate follow-up and to protect against coronavirus disease 2019, he has been temporarily suspended until the final assignment.

RESUMO

BACKGROUND: Chest CT may be used for the diagnosis of coronavirus disease 2019 (COVID-19), but clear scientific evidence is lacking. Therefore, we systematically reviewed and meta-analyzed the chest CT imaging signature of COVID-19. RESEARCH QUESTION: What is the chest CT imaging signature of COVID-19 infection? STUDY DESIGN AND METHODS: A systematic literature search was performed for original studies on chest CT imaging findings in patients with COVID-19. Methodologic quality of studies was evaluated. Pooled prevalence of chest CT imaging findings were calculated with the use of a random effects model in case of between-study heterogeneity (predefined as I2 ≥50); otherwise, a fixed effects model was used. RESULTS: Twenty-eight studies were included. The median number of patients with COVID-19 per study was 124 (range, 50-476), comprising a total of 3,466 patients. Median prevalence of symptomatic patients was 99% (range, >76.3%-100%). Twenty-seven of the studies (96%) had a retrospective design. Methodologic quality concerns were present with either risk of or actual referral bias (13 studies), patient spectrum bias (eight studies), disease progression bias (26 studies), observer variability bias (27 studies), and test review bias (14 studies). Pooled prevalence was 10.6% for normal chest CT imaging findings. Pooled prevalences were 90.0% for posterior predilection, 81.0% for ground-glass opacity, 75.8% for bilateral abnormalities, 73.1% for left lower lobe involvement, 72.9% for vascular thickening, and 72.2% for right lower lobe involvement. Pooled prevalences were 5.2% for pleural effusion, 5.1% for lymphadenopathy, 4.1% for airway secretions/tree-in-bud sign, 3.6% for central lesion distribution, 2.7% for pericardial effusion, and 0.7% for cavitation/cystic changes. Pooled prevalences of other CT imaging findings ranged between 10.5% and 63.2%. INTERPRETATION: Studies on chest CT imaging findings in COVID-19 suffer from methodologic quality concerns. More high-quality research is necessary to establish diagnostic CT criteria for COVID-19. Based on the available evidence that requires cautious interpretation, several chest CT imaging findings appear to be suggestive of COVID-19, but normal chest CT imaging findings do not exclude COVID-19, not even in symptomatic patients.

RESUMO

PURPOSE: We aimed to demonstrate the computed tomography (CT) findings observed at the initial presentation of coronavirus disease 2019 (COVID-19) pneumonia and reveal the most frequent infiltration and distribution patterns of the disease. METHODS: One hundred and eighty-five patients (87 men, 98 women; mean age, 48.7 years), who underwent RT-PCR sampling and high-resolution CT examination in our hospital between March 15, 2020, and April 15, 2020, and got a definitive diagnosis of COVID-19 disease via initial or follow-up RT-PCR test, were included in the study. We comprehensively analyzed the most common and relatively rare CT imaging features (e.g., distribution pattern, density of the lesions, additional CT signs) in patients diagnosed with COVID-19 pneumonia. RESULTS: Thirty-eight patients (20.6%) had no evidence of pneumonia on their initial high-resolution CT images. Among 147 patients (79.4%) who had parenchymal infiltration consistent with pneumonia, 10 (6.8%) had a negative baseline RT-PCR test, and positivity was detected as a result of repeated tests. Most of the patients had multifocal (89.1%) and bilateral (86.4%) lesions. The most common location, right lower lobe, was affected in 87.8% of the patients. Lesions were distributed predominantly at peripheral (87.1%) and posterior (46.3%) areas of lung parenchyma. Most of the patients had pure ground glass opacity (GGO) (82.3%) followed by GGO with consolidation (32.7%) and crazy paving pattern (21.8%). Pure consolidation, solid nodules, halo sign, reverse halo sign, vascular enlargement, subpleural line, air-bronchogram, and bronchiectasis were the other findings observed in at least 15% of the cases. Halo sign, acinar nodules, air-bubble sign, pleural thickening and effusion, mediastinal and/or hilar lymphadenopathy were seen rarely (2%-12.9%). Pericardial effusion, pneumothorax, cavitation, and tree-in-bud pattern were not detected in our study group. CONCLUSION: Multifocal and bilateral GGO infiltration predominantly distributed in peripheral, posterior, and lower lung areas was the most common infiltration pattern.

RESUMO

The disease caused by the new coronavirus, or COVID-19, has been recently described and became a health issue worldwide. Its diagnosis of certainty is given by polymerase chain reaction. High-resolution computed tomography, however, is useful in the current context of pandemic, especially for the most severe cases, in assessing disease extent, possible differential diagnoses and searching complications. In patients with suspected clinical symptoms and typical imaging findings, in which there is still no laboratory test result, or polymerase chain reaction is not available, the role of this test is still discussed. In addition, it is important to note that part of the patients present false-negative laboratory tests, especially in initial cases, which can delay isolation, favoring the spread of the disease. Thus, knowledge about the COVID-19 and its imaging manifestations is extremely relevant for all physicians involved in the patient care, clinicians or radiologists.

RESUMO

OBJETIVOS: La región inguinal es un área anatómica compleja que ha sido tradicionalmente olvidada por los radiólogos dado que la mayoría de las lesiones pueden diagnosticarse mediante datos clínicos y con la exploración física. No obstante, cada vez es más frecuente la solicitud de ecografías, bien para confirmar la existencia de patología o para resolver casos dudosos. Por otra parte, la patología inguinal incluye entidades únicas de la edad infantil. El objetivo de este trabajo es describir los hallazgos radiológicos clave de las lesiones inguinales pediátricas, poniendo especial énfasis en los datos ecográficos CONCLUSIONES: El conocimiento de la patología inguinal pediátrica y sus claves en imagen ayudan a mejorar el rendimiento diagnóstico de la ecografía


OBJECTIVES: The groin is a complex anatomic region that has traditionally been ignored by radiologists because most lesions can be diagnosed from clinical data and physical examination. Nevertheless, ultrasound examinations of the groin are increasingly being requested to confirm injury or to resolve diagnostic uncertainty. On the other hand, some conditions involving the groin are found only in pediatric patients. This article describes the key imaging findings in pediatric groin injuries, placing special emphasis on the ultrasound appearance. CONCLUSIONS: Knowledge about conditions that can affect the groin in pediatric patients and the key imaging findings associated with them helps improve the diagnostic performance of ultrasound

RESUMO

Objective: The aim of this study was to detect the prevalence of soft tissue calcifications in the head and neck using cone beam computed tomography (CBCT) and to determine their clinical importance. Subjects and Methods: Soft tissue calcifications in the head and neck region were retrospectively evaluated in 1557 CBCT images obtained between 2013 and 2015. The findings were categorized as follows: tonsillolith (calcified tonsil), carotid artery calcification (CAC), sialolith (salivary stone), calcified triticeous cartilage (CTC), calcified lymph node (CLN), rhinolith, antrolith, calcification of the superior cornu of the thyroid cartilage (CSCTC), calcified stylohyoid ligaments (CSL), myositis ossifican, osteoma cutis, and intracranial calcification. A Chi-square test was performed for categorical variables. In the 1557 CBCT images, 520 (33.4%) contained had at least one soft tissue calcification in the head and neck region. Results: Tonsilloliths (18.8%) were the most prevalent soft tissue calcification, followed by CTC (5.8%), CAC (4.3%), intracranial calcifications (3.9%), CSL (3.7%), CSCTC (2.1%), osteoma cutis (1%), sialoliths (0.7%), antroliths (0.5%), myositis ossificans (0.4%), rhinoliths, and CLN (0.2%). Conclusion: There was a high prevalence of soft tissue calcifications in the head and neck region on CBCT images. Tonsilloliths were the most common type of calcification. CBCT imaging may aid the diagnosis and assessment of these calcifications.
