Incidental chest computed tomography findings in asymptomatic Covid-19 patients. A multicentre Indian perspective

Indian journal of radiology and imaging - new series/Indian journal of radiology and imaging/Indian Journal of Radiology & Imaging (2021)

Rochita Venkata Ramanan Anagha Joshi Akash Venkataramanan Senthur P Nambi Rashmi Badhe

In December 2019, an unprecedented outbreak of pneumonia of unknown etiology emerged called COVID-19. A vast number of people affected by this disease are asymptomatic and yet contagious with up to 79% of COVID-19 infections reportedly caused by undocumented infections. Surprisingly, these asymptomatic subjects are also known to quietly harbor pneumonia changes on CT scans. RT-PCR, the definitive test for COVID-19, maybe false negative in patients with COVID-19 pneumonia on CT. Incidental findings highly suspicious of COVID-19 pneumonia on CT chest of asymptomatic patients may increase as the community transmission of the virus rises and isolation restrictions are released. It is advisable to be aware of its appearances and the challenges associated with it.

A Chronic Cough and Something More: An Unusual Presentation of Hepatocellular Carcinoma

Cureus (2023)

M.C. Cuartas-Mesa Maria E Romero Noboa Yasmine Choroomi Badri Aryal Akash Venkataramanan

Liver cancer is one of the main contributors to cancer-related death and is the fifth most frequent cancer worldwide. Hepatocellular carcinoma (HCC), the most common of liver cancers, is most frequently diagnosed incidentally during routine imaging in high-risk patients with cirrhosis. However, patients with advanced disease may present with upper abdominal pain, early satiety, weight loss, and a palpable upper abdominal mass. We describe a case of HCC in a 69-year-old male presenting exclusively with an intractable cough, which improved after transarterial chemoembolization-raising awareness of the importance of having a systematic and physiopathology-based approach to chronic cough to have an adequate diagnosis and treatment.

Acute Renal Infection in Adult, Part 1: An Overview of What the Radiologist Needs to Know

Deleted Journal (2019)

Suman Hazarika Rochita Venkataramanan Tonmoy Das Sukanya Deuri Shalini Lohchab

Abstract Acute renal infection or acute pyelonephritis (AP) denotes the process of inflammation of the renal parenchyma and its collecting system and the urothelium following infection. Uncomplicated AP commonly affects otherwise healthy, young women without structural or functional urinary tract abnormalities and without relevant comorbidities. More severe and complicated AP occurs in patients with a structurally or functionally abnormal genitourinary tract, or in persons with a predisposing medical condition like immune compromised state and diabetes. Complicated AP is characterized by a broader spectrum of clinical presentations, a wider variety of infecting organisms, and a greater risk of progression to a complication, such as intrarenal or perinephric abscess or emphysematous pyelonephritis and has the capacity to damage the organ and at times maybe life threatening. Role of imaging in renal infection is secondary, and in most situations, imaging is done to confirm the clinical diagnosis, map progression of disease in immune-compromised group of patients, or to evaluate for potential complications and therapeutic interventions. This article attempts to discuss the pathophysiology of AP from the standpoint of medical imaging and also brings out illustrative examples of various manifestations of AP and its complications. It provides imaging insight into various stages of inflammation, development of complication, and a roadmap for understanding AP through cross-sectional imaging.

Background Magnetic resonance imaging (MRI) is the gold standard for local staging of rectal cancer.Advanced computed tomography (CT) machines are now capable of high-resolution images of rectal cancer and utilized for CT perfusion.The possibility of local staging of rectal cancer by CT needs to be explored.Purpose The aim of the study is to evaluate accuracy of high-resolution CT for local rectal cancer staging.Methods A high-resolution CT was performed for local staging of rectal cancer in our study group of 93 patients, where 64 underwent primary surgery and 29 underwent surgery post neoadjuvant chemoradiotherapy (NACRT). ResultsIn differentiating stages T2-and-less than T2 from T3-T4 rectal cancer, accuracy, sensitivity, specificity, and kappa score in overall patients were 91%, 87%, 94%, and 0.8; in primary surgery group were 89%, 76%, 94%, and 0.7; in NACRT group were 97%, 100%, 94%, and 0.9; in low rectal group were 94%, 89%, 97%, and 0.82, respectively.Conclusion High resolution CT is an accurate tool for local staging of rectal cancer.
