COVID-19 disease is caused by a new variant of coronavirus, named as ‘severe acute respiratory syndrome coronavirus 2.’ Chest CT has a potential role in the diagnosis, detection of complications and in predicting clinical recovery of patients or progression of coronavirus disease 2019. Degree and severity of lung involvement can be assessed by 25 point CT severity score. This quantification plays an important role to modify the treatment plan at times in critically ill patient of COVID-19. Hence, the purpose of present study was to describe and quantify the severity of COVID-19 infection on chest computed tomography (CT) by 25-point CT severity score and to determine the relationship of CT severity score with clinical and laboratory parameters. Results A total of 150 patients with COVID-19 disease were assessed. Mean age of the stud...

This is attributed to the immunomodulation by the disease and the drugs used, diabetes mellitus, steroid use, oxygen inhalation using dirty water, use of zinc and iron supplements, etc. Early diagnosis and prompt medical and surgical intervention is the mainstay of treatment. This can greatly reduce the high morbidity and mortality associated with this disease. The objective of the study is to describe the imaging findings of acute invasive rhino-orbito-cerebral mucormycosis (ROCM) in 25 patients with severe acute respiratory syndrome corona virus 2, from three different centers with proven mucormycosis. Special emphasis is placed on the signal enhancement patterns of sinonasal mucosa, the earliest and most common findings. Statistical analysis was performed using descriptive statistics. Results Computed tomography (CT) and magnetic resonance imaging (MRI) of 25 patients showed most commonly involved si...

It is largely seen in Asian, African and alternative non-developed countries and might occur with coincident primary tuberculosis of the respiratory tract or spine. Primary breast tuberculosis (TB) is even rarer and presents with non-specific clinical signs of continual breast masses, inflammation and sinus tracts. It can be similar to bacterial inflammation/abscess and malignant pathologies on imaging. The key to identification could be a holistic combination of imaging, clinical, biochemical and histopathological analysis. Case presentation We discuss a case of a 41-year-old lady who conferred at the start with tender breast nodules that progressed to continual, multiple abscesses and sinus tract formation. It had been an unusual and unanticipated presentation in breast followed by uncommon events throughout the course of the treatment forcing us to re-evaluate the primary diagnosis. A sequence of multiple diagnostic imaging and histopathological evaluations confirmed the identification of tubercular mastitis. Following prolonged treatment, there was vital reduction within the range and size of nodules and abscesses. Conclusions Such cases imitate bacterial abscess and cancer in their clinical presentation and imaging findings and are imperative to be diagnosed via a myriad of diagnostic tests with histopathology. Such a clinical presentation should warrant a differential of granulomatous inflammation of the breast in cases of non-responders to incision and drainage, prolonged antibiotic medical therapy and prolonged anti-tubercular treatment up to twenty four months after assessment of the individual response.

Its presentation mimics the symptoms of tubal ectopic pregnancy, hemorrhagic ovarian cyst/follicle, tuboovarian abscess, urinary tract calculi, appendicitis or ovarian torsion. Occasionally determining the anatomic location of an extra-tubal ectopic pregnancy based on ultrasound imaging and presentation alone can be challenging, particularly when it is adherent to the fallopian tube. Although transvaginal ultrasound (TVS) is the primary modality used in the diagnosis, various forms of OEP and its complications may be incidentally detected and further evaluated on computed tomography (CT) or magnetic resonance imaging (MRI) when an alternative diagnosis is suspected. We reported a case of a second gravid para zero, 25 years old lady, who came with pain in the left lower abdomen. Her urine pregnancy test was positive. TVS showed empty uterine cavity, an extremely tender, heterogenous hyperechoic right adnexal mass, but no obvious gestation sac (GS). A large hematoma was detected adjacent to it in the pouch of Douglas (POD). Keeping a high suspicion of ectopic pregnancy, MRI was performed to evaluate the lesion better which revealed a natural, non-assisted, ruptured right ovarian ectopic pregnancy and was subsequently confirmed at laparotomy and proven on histopathology. Patient underwent left oophorectomy and discharged on 4th day with uneventful follow up.

This is attributed to the immunomodulation by the disease and the drugs used, diabetes mellitus, steroid use, oxygen inhalation using dirty water, use of zinc and iron supplements, etc. Early diagnosis and prompt medical and surgical intervention is the mainstay of treatment. This can greatly reduce the high morbidity and mortality associated with this disease. The objective of the study is to describe the imaging findings of acute invasive rhino-orbito-cerebral mucormycosis (ROCM) in 25 patients with severe acute respiratory syndrome corona virus 2, from three different centers with proven mucormycosis. Special emphasis is placed on the signal enhancement patterns of sinonasal mucosa, the earliest and most common findings. Statistical analysis was performed using descriptive statistics. Results: Computed tomography (CT) and magnetic resonance imaging (MRI) of 25 patients showed most commonly involved sinuses as maxillary and ethmoid sinuses (19, 76%) together. Sino-nasal mucosal thickening was the most common finding (24, 96%). Periantral infiltration (18, 72%) preceded before orbital (15, 60%), cerebral (5, 20%) and vascular (2, 8%) complications, with grossly intact bones. Sinus wall erosions were seen in only 2 patients (8%). Palatal (22%) and maxillary alveolar arch erosion (39%) were frequent findings. CT showed minimally enhancing hypodense soft tissue thickening as the predominant finding in involved areas, while MRI showed T1 and T2 iso-to hypointense mucosal thickening (62%) and intense (43%) and no (33%) contrast enhancement as the main finding. Conclusions: Contrast enhanced MRI is better at demonstrating early mucosal abnormalities, turbinate necrosis, non-enhancing devitalized tissues, orbital apex involvement and intra-cerebral extension. Imaging findings of inflammatory tissue infiltration adjacent to the paranasal sinuses in premaxillary, retroantral fat, facial muscles, pterygopalatine fossa, temporal, infratemporal fossa and extraconal orbital fat along with typical patterns of sinonasal mucosal enhancement should raise the suspicion of acute invasive fungal etiology given the short duration of history and immunocompromised status. High incidence of periantral and orbital extension of the disease is suggestive of acute invasive form of fungal infection. Also the rapidly progressive inflammatory changes without much bone involvement should suggest the suspicion of ROCM. Bony, cerebral and vascular involvements are relatively late complications.

COVID-19 disease is caused by a new variant of coronavirus, named as 'severe acute respiratory syndrome coronavirus 2. ' Chest CT has a potential role in the diagnosis, detection of complications and in predicting clinical recovery of patients or progression of coronavirus disease 2019. Degree and severity of lung involvement can be assessed by 25 point CT severity score. This quantification plays an important role to modify the treatment plan at times in critically ill patient of COVID-19. Hence, the purpose of present study was to describe and quantify the severity of COVID-19 infection on chest computed tomography (CT) by 25-point CT severity score and to determine the relationship of CT severity score with clinical and laboratory parameters. Results: A total of 150 patients with COVID-19 disease were assessed. Mean age of the study group was 54.46 years (62.7% males and 37.3% females). The most common comorbidity present in the study group was diabetes mellitus, which was present in 17.3% cases. Severity of disease was significantly associated with age of the patient. CT severity score was positively correlated with lymphopenia and raised CRP, D-dimer and serum ferritin levels. A significant statistical correlation was found between CT severity grade and patient survival. Conclusions: This is a large comprehensive study, collecting data from 150 cases of COVID-19 pneumonia patients, in a tertiary care hospital in India to describe the correlation of CT severity score with clinical land laboratory parameters. Chest CT severity score correlates well with laboratory parameters and can aid in predicting COVID-19 disease outcome.

Correlation between various lab parameters and severity of the disease on chest CT would be helpful in management of such patients. In situations where CT is not available, lab parameters may help to predict disease severity. The primary objective was to find out if there was any correlation between CT severity scores and laboratory parameters in patients having COVID-19 and if one can be extrapolated in cases where CT facilities may not be available. Methods: This is a retrospective, descriptive, and observational study. CT severity scores were obtained in all the patients using the 25 point scale. The following lab parameters were assessed: TLC, DLC, SGOT, SGPT, CRP, D-Dimer, IL-6, Serum Ferritin and serum LDH. Correlation was done between the CT score and various lab parameters using Pearson correlation coefficient test. Results: 285 patients with positive COVID-19 RT-PCR test were included in the study. CT score showed statistically significant positive correlation with age, TLC, Neutrophil count, SGOT, SGPT, CRP, D-dimer, IL-6, Ferritin and LDH with p-values less than 0.05. Negative correlation was seen with Lymphocyte count. Severe disease was found to be more common in older patients. Conclusions: In our study, CRP, LDH, Serum ferritin, IL-6 and D-dimer levels were observed to have positive correlation with disease severity on CT. Thus these measured at the time of admission can be taken into consideration to predict radiological severity.

The acardiac twin is dependent upon the normal twin to provide circulation by means of vascular anastomosis, thereby putting the pump fetus at risk of high output cardiac failure. Overall only 50% of pump twins survive. Mortality for acardiac twin is 100%. We present a case of 26-year-old primigravida female presenting with 8 months of amenorrhea with unsure LMP. Ultrasonography followed by fetal MRI was carried out which revealed acardius acephalus twin with absence of blood flow in umbilical vessels. Pump twin had multicystic dysplastic left kidney with single umbilical artery. Following delivery, the pump twin survived well and the deformed fetus showed features of twin reversed arterial perfusion syndrome.

Children with this anomaly can present with choledochal cyst with recurrent attacks of acute pancreatitis, and their condition can be worse when not treated appropriately. Pancreaticobiliary maljunction or anomaly is considered to be a major risk factor for biliary tract cancer. In patients with this anomaly, free reflux of pancreatic juice into biliary tract may cause biliary tract damage. This can result in biliary malignancy. Therefore, in this condition, total excision of the extrahepatic bile duct with hepaticojejunostomy is recommended. Early diagnosis of this condition and early surgical treatment is recommended to prevent further complications. Proper follow-up is necessary to detect biliary tract malignancy in the early post-operative period, especially in patients demonstr...

It should be differentiated from a teratoma because of the later’s malignant potential. Here we report a case of 2 months old girl child who presented with complaints of abdominal distension. USG showed a solid cystic retroperitoneal mass resembling an anencephalic fetus. Contrast enhanced Computed tomography (CT) showed similar findings with visualization of bones resembling femur, sacrum and vertebrae. Findings were correlated with MRI and post-op pathology. The preoperative diagnosis of FIF is based on the observation of vertebral column or limbs in a mass on imaging modalities and our case meets the required criteria.
