Introduction: Prenatal suprarenal lesions represent diverse pathologies. This study investigated prenatal imaging features and regression patterns associated with specific lesion diagnoses. Methods: This is a multicenter retrospective review of fetuses with prenatally diagnosed suprarenal lesions between 2001 and 2019. Prenatal ultrasound and MRI characteristics, postnatal imaging, and clinical course were reviewed. Prenatal imaging findings were compared by the most common diagnoses and regression patterns. Results: Forty-four fetuses were prenatally diagnosed with suprarenal lesions. Diagnoses included pulmonary sequestration (n = 12; 27.3%), adrenal hemorrhage (n = 12; 27.3%), upper quadrant cyst (including 2 duplication cysts, 1 splenic cyst, and 3 indeterminate cysts), neuroblastoma (n = 4), adrenal hyperplasia (n = 3), bilateral adrenal calcifications (n = 1), and indeterminate lesions (n = 6). Sequestrations were uniformly left-sided (100 vs. 50%; p = 0.014) and diagnosed earlier in gestation than adrenal hemorrhages (p = 0.025). Sequestrations were also significantly more likely to have a prenatal feeding vessel (p = 0.005), low T1 MRI signal (p = 0.015), and no MRI blood products (p = 0.018) compared to adrenal hemorrhages. When comparing all 44 patients, a prenatal feeding vessel and low T1 signal on prenatal MRI were significantly associated with lesion persistence (p = 0.003; p = 0.044). Discussion/Conclusion: Imaging findings on prenatal ultrasound and MRI aid in the diagnosis of suprarenal lesions, including differentiating pulmonary sequestrations and adrenal hemorrhages.

Intracranial echinococcosis is relatively uncommon and usually occurs in the context of echinococcal lesions elsewhere in the body, mostly liver and lung. Multiple intracranial lesions can result from rupture of an initial single intracranial cyst (in cystic echinococcosis) or from dissemination of systemic disease of the lung, liver or heart (cystic and alveolar echinococcosis). The two main subtypes, cystic and alveolar echinococcosis, present differently and have distinct imaging features in the brain. We discuss the presentation, imaging findings and clinical course of three cases (two cystic and one alveolar) of intracranial echinococcal disease in adults.

Background: Metaplastic breast cancer (MC) is a rare disease, thus it is difficult to study its clinical outcomes. Objective: To investigate whether any clinicopathological or imaging features were associated with clinical outcome in MC. Methods: We retrospectively evaluated the clinicopathological and imaging findings, and the clinical outcomes of seventy-two pathologically confirmed MCs. We then compared these parameters between triple-negative (TNMC) and non-TNMCs (NTNMC). Results: Oval or round shape, and not-circumscribed margin were the most common findings on mammography, ultrasound (US), and magnetic resonance imaging (MRI). It was mostly a mass without calcification on mammography, and revealed complex or hypoechoic echotexture, and posterior acoustic enhancement on US, and rim enhancement, wash-out kinetics, peritumoral edema, and intratumoral necrosis on MRI. Of all 72, 64 were TNMCs, and eight were NTNMCs. Clinicopathological and imaging findings were similar between the two groups, except that MRI showed peritumoral edema more frequently in TNMCs than NTNMCs (p=0.045). There were 21 recurrences and 13 deaths. Multivariable analysis showed that larger tumor size and co-existing DCIS were significantly predictive of Disease free survival (DFS), and larger tumor size and neoadjuvant chemotherapy were significantly predictive of overall survival (OS). Conclusion: MC showed characteristic imaging findings, and some variables associated with survival outcome may help to predict prognosis.

AbstractOur understanding of the manifestations of pneumoconioses is evolving in recent years. Associations between novel exposures and diffuse interstitial lung disease have been newly recognized. In advanced asbestosis, two types of fibrosis are seen, probably related to dose of exposure, existence of pleural fibrosis, and the host factor status of the individual. In pneumoconiosis of predominant reticular type, nodular opacities are often seen in the early phase. The nodular pattern is centrilobular, although some in metal lung show perilymphatic distribution, mimicking sarcoidosis. High-resolution computed tomography enables a more comprehensive correlation between the pathologic findings and clinically relevant imaging findings. The clinician must understand the spectrum of characteristic imaging features related to both known dust exposures and to historically recent new dust exposures.

Abstract Background The aim of this study was to highlight the typical and atypical chest CT imaging features at first presentation in 120 patients who were proved to be COVID-19 by PCR and to correlate these findings with the need for ICU admission, ventilation, and mortality. We retrospectively included 120 patients 71 males (59.2%) and 49 females (40.8%) with a mean age of 47.2 ± 14.4 years. Patients subjected to clinical assessment, CBC, PCR for COVID-19, and non-contrast CT chest at first presentation. Typical and atypical imaging findings were reported and correlated with the clinical findings of the patients, the need for ICU admission, ventilation, and mortality. Results Clinically, fever was seen in 112 patients followed by dry cough in 108 patients and malaise in 35 patients. The final outcome was complete recovery in 113 cases and death in 7 cases. Typical CT findings included bilateral peripheral ground-glass opacities (GGO) in 74.7%, multilobar affection in 92.5% while atypical findings such as homogeneous consolidation, pleural effusion, mediastinal lymphadenopathy, and single lobar affection were found in 13.4, 5, 6.7, and 7.5% respectively. A statistically significant association between the presence of white lung, pleural effusion, peripheral GGO, and the need for ICU admission as well as mechanical ventilation was noted. The death was significantly higher among elderly patients; however, no significance was found between the imaging features and mortality. Conclusion CT features at first presentation can predict the need for ICU admission and the need for ventilation but cannot predict the mortality outcome of the patients.

AbstractObjectives:We report a case of otogenic fungal pachymeningitis in a diabetic patient who presented with multiple cranial nerve palsies and nasopharyngeal swelling.Methods:We present a case report, we describe the investigations, management and clinical course of fungal pachymeningitis, and we present a review of the world literature on fungal and non-fungal pachymeningitis.Results:To our knowledge, this is the first report of fungal pachymeningitis with magnetic resonance imaging features suggestive of nasopharyngeal carcinoma. It is also the first reported case with aspergillus cultured from both a dural biopsy and the ear canal.Conclusion:Fungal pachymeningitis is a rare condition which may present to otorhinolaryngologists. Its clinical and radiological findings can be confused with those of nasopharyngeal carcinoma; fungal pachymeningitis should thus be included in the differential diagnosis of nasopharyngeal carcinoma.

In this report we describe the MR imaging findings, including dynamic data, in a patient with primary non-Hodgkin's lymphoma of the breast. The precontrast T1-weighted sequence showed several hypointense, ill-defined, non-spiculated masses. In the T2-weighted images the masses showed a hyperintense halo. In the dynamic and postcontrast sequences all lesions enhanced markedly, and a further large mass was discovered. In comparison to mammography and sonography, only MR imaging identified the multicentric extent of the tumour. Differentiation from invasive cancer, based on either MR or conventional imaging features, was not possible.

Background: Acute bacterial nephritis is an infectious process diagnosed through imaging studies. The clinical course of the disease has been shown to be more aggressive than acute pyelonephritis. It continues to be underdiagnosed, thus there are few studies on the entity in the literature. Objective: To describe the clinical characteristics and imaging features of acute bacterial nephritis, as well as its clinical course. Design: A descriptive, retrospective case series was conducted. Materials and methods: Thirty-two cases of acute bacterial nephritis in patients admitted to the hospital within the time frame of 2009 to 2016 were reviewed. The patients’ clinical characteristics upon admission were registered, as well as inpatient clinical progression, culture results, and antibiotic therapy response. The imaging studies were re-evaluated and the diagnostic consistency with either the focal or multifocal disease presentation was confirmed. Results: Cases predominated in women (n=29, 90.62%) and the most frequently associated comorbidities were diabetes (n=16, 50%) and obesity (n=9, 28.25%). The most important clinical findings upon admission were fever (n=15, 46.87%) and leukocytosis (n=27, 84.38%). Escherichia coli was the most commonly isolated bacterium (63.63%). Both acute focal bacterial nephritis and acute multifocal bacterial nephritis were observed in 46.87% (n=15) and 53.13% (n=17) of the patients, respectively. Imaging studies were required for all diagnoses. Conclusion: Fever and leukocytosis are the main findings in acute bacterial nephritis. Imaging studies are necessary for making the diagnosis, given that acute pyelonephritis and acute bacterial nephritis cannot be clinically differentiated.
