Norovirus-Induced Gastroenteritis Presenting With Reversible Quadriparesis In An Adult Suggesting Transient Intramyelinic Edema: A Rare Case Report

Neuromuscular weakness with no plausible cause other than critical illness has been labeled as an intensive care-acquired weakness. There are myriad causes of neuromuscular weakness in intensive care unit (ICU). Here, we present the case of an adult with a diagnosis of acute gastroenteritis due to Norovirus with acute kidney injury and sepsis presenting with acute flaccid quadriparesis which recovered fully before ICU discharge. Magnetic resonance imaging brain of this patient suggested white matter diffusion restriction with normalization of diffusion abnormality after 2 months, suggesting “transient intramyelinic edema.” We highlight that Norovirus gastroenteritis can present as myelin sheath edema causing quadriparesis mimicking other etiologies for neuromuscular weakness in ICU and discussed the various differential diagnoses of white matter demyelination and diffusion restriction in this case report.

Left ventricular non-compaction with multiple ventricular septal defects

Left ventricular non?compaction [LVNC] is a congenital cardiomyopathy characterized by deep ventricular trabeculations thought to be due to an arrest of myocardial morphogenesis. Integration of various cardiac imaging modalities such as echocardiography, cardiac computed tomography and cardiac magnetic resonance imaging help in the diagnosis of this rare clinical entity. We describe a child with rare variant of LVNC with predominant involvement of interventricular septum resulting in multiple ventricular septal defects

Diffuse large B-cell non-Hodgkin lymphoma of the prostate presenting with urinary outlet obstruction: a case report

Large B-cell non-Hodgkin lymphoma involving the prostate accounts for 0.09% and 0.1% of non-Hodgkin lymphoma. We report a case of prostatic large B-cell non-Hodgkin lymphoma in a 77-year-old male with symptoms of urinary retention most probably due to benign prostate hyperplasia. He underwent multiple needle core biopsies through transrectal ultrasound of the prostate. Histopathological examination of the core biopsies revealed diffuse infiltration by atypical lymphoid cells in the prostatic stroma, which was strongly positive for leukocyte common antigen and CD20. CD3, CK, PSA, BCL2, k-light chain, Cyclin D1 and synaptophysin were negative. Histopathology and immunohistochemical profile in the case was consistent with the diagnosis of diffuse large B-cell non-Hodgkin lymphoma of the prostate

How to Perform and Interpret Timed Barium Esophagogram

Timed barium esophagogram (TBE) is a simple and objective method for assessing the esophageal emptying. The technique of TBE is similar to usual barium swallow with some modifications, which include taking multiple sequential films at pre-decided time interval after a single swallow of a fixed volume of a specific density barium solution. While many authors have used height and width of the barium column to assess the esophageal emptying, others have used the area of the barium column. TBE is being used in patients with suspected or confirmed achalasia and to follow-up those who have been treated with pneumatic dilation or myotomy. This review discusses technique of performing TBE, interpretation and its utility in clinical practice.

CT-Guided Percutaneous Biopsy of Intrathoracic Lesions

Percutaneous CT-guided needle biopsy of mediastinal and pulmonary lesions is a minimally invasive approach for obtaining tissue for histopathological examination. Although it is a widely accepted procedure with relatively few complications, precise planning and detailed knowledge of various aspects of the biopsy procedure is mandatory to avert complications. In this pictorial review, we reviewed important anatomical approaches, technical aspects of the procedure, and its associated complications.

The Utility of 64 Channel Multidetector CT Angiography for Evaluating the Renal Vascular Anatomy and Possible Variations: a Pictorial Essay

The increased use of laparoscopic nephrectomy and nephron-sparing surgery has prompted the need for a more detailed radiological evaluation of the renal vascular anatomy. Multidetector CT angiography is a fast and accurate modality for assessing the precise anatomy of the renal vessels. In this pictorial review, we present the multidetector CT angiography appearances of the normal renal vascular anatomy and a spectrum of various anomalies that require accurate vascular depiction before undergoing surgical treatment.
