Malignant Degeneration of a Peripheral Nerve Sheath Tumor in the Neck Region.

Malignant transformation of neurofibromas into malignant peripheral nerve sheath tumors (MPNST) is a rare but aggressive phenomenon, particularly in the head and neck region, and is associated with a poor prognosis. The primary treatment modality is surgical excision, often followed by radiotherapy. This is a case report of MPNST in the neck, with long-term follow-up.

Fusarium spp. causing invasive disease in humans: A case series from north India.

Owing to their inherent resistance to different classes of antifungals, early identification of Fusarium spp. is crucial. In this study, 10 clinical isolates were included from patients with invasive fusariosis involving lungs, sinuses, or both.

Pre-vascular Facial Nodes: Sentinel Station for Metastasis in Gingivobuccal Complex Cancers.

Background: Pre-vascular facial nodes (PV-FNs; perifacial lymph nodes) are supra-mandibular lymph nodes above the inferior border of the mandible. These are not part of routine neck dissection done for OCSCC. These lymph nodes can be sentinel station for metastatic lymph nodes from gingivobuccal complex cancers and are missed during routine neck dissection.

Pediatric hemoptysis: diagnostic and interventional challenges.

Hemoptysis in the pediatric population, while infrequent, poses significant challenges for both the family and healthcare practitioners. The severity of hemoptysis dictates management decisions. Most cases being mild and self-limiting are treated conservatively.

Neck lump evaluation and pseudoaneurysm.

Pseudoaneurysm is the formation of a sac due to damage in the continuity of the arterial wall. Iatrogenic carotid artery aneurysm is a rare, life-threatening complication following fine needle aspiration (FNA). We are presenting here a case of pseudoaneurysm following FNA with a literature review.

Endemic pediatric fungal infections in India: clues to diagnosis.

This review is intended to familiarize readers with an emerging group of fungal infections that mostly manifest in immunocompetent individuals. This group was initially considered endemic to the tropics, but increasing worldwide prevalence has been reported. The organisms have been divided into dominant non-invasive forms and dominant invasive forms for ease of understanding.

Linking Non-alcoholic Fatty Liver Disease Severity With Metabolic Syndrome Features: An Integrative Study on Clinical and Radiological Fronts.

Introduction Non-alcoholic fatty liver disease (NAFLD) has become a widespread cause of chronic liver disease, ranging from simple steatosis to severe conditions like non-alcoholic steatohepatitis (NASH) and cirrhosis. Despite its similarity to alcohol-induced liver damage, NAFLD affects individuals with no significant alcohol consumption. This study explores the association between NAFLD, bone mineral density (BMD), insulin resistance, and subclinical inflammation, focusing on the Asian Indian population.

Characterization of tumors of jaw: Additive value of contrast enhancement and dual-energy computed tomography.

Background: Currently, the differentiation of jaw tumors is mainly based on the lesion's morphology rather than the enhancement characteristics, which are important in the differentiation of neoplasms across the body. There is a paucity of literature on the enhancement characteristics of jaw tumors. This is mainly because, even though computed tomography (CT) is used to evaluate these lesions, they are often imaged without intravenous contrast.

Role of CD34-immunopositive Microvascular Density in Juvenile Nasopharyngeal Angiofibroma.

Objective: To assess the microvascular density (MVD) in juvenile nasopharyngeal angiofibroma (JNA) with CD34 immunostaining and evaluate its relationship with clinico-demographic features.

Methods: This prospective study included patients with JNA undergoing endoscopic excision. The histopathological specimen was stained using CD-34 antibodies to calculate MVD.

Ultrasound in Causes of Stridor in Children.

Airway ultrasound (US) is an easily available, portable, radiation-free imaging modality for quick, non-invasive, dynamic evaluation of the airway without sedation. This is useful in children with stridor, which is an emergency due to upper airway obstruction requiring immediate management. Several causes of stridor including laryngomalacia, laryngeal cyst, subglottic hemangioma, vocal cord palsy, and lymphatic malformations can be evaluated accurately.

MDCT and MRI in Bronchiectasis in Older Children and Young Adults - A Non-Inferiority Trial.

Objectives: To compare and evaluate the usefulness of magnetic resonance imaging (MRI) with computed tomography (CT) in bronchiectasis; to compare MRI and CT scores with pulmonary function tests (PFT) and to evaluate the role of Diffusion-weighted imaging (DWI) in bronchiectasis.

Methods: In this prospective study, 25 patients between 7-21 y of age with a clinical/radiological diagnosis of bronchiectasis underwent MDCT and MRI chest. MRI and CT scoring was performed using modified Bhalla-Helbich's score by two independent radiologists for all parameters.

Ultrasound Characteristics of Metastatic Occult Cervical Lymph Nodes in Early Tongue Cancer.

Identification of occult lymph node metastasis is challenging in early tongue cancers. We conducted a prospective study to determine the most characteristics ultrasonic feature suggestive of metastatic node. A preliminary study based on feasibility was planned on twenty five patients with squamous cell carcinoma of tongue (T1,T2) and N0 neck underwent ultrasonography of neck.

Comparison of 68Ga-PSMA-HBED-CC and 18F-FDG PET/CT in the Evaluation of Adenoid Cystic Carcinoma-A Prospective Study.

Purpose Of Study: 18F-FDG PET/CT plays a major role in diagnosis and staging of head and neck cancer; however, FDG has lower uptake in adenoid cystic carcinoma (AdCC). Prostate-specific membrane antigen (PSMA) expression is found to be associated with endothelial cells or tumor neovasculature in malignant AdCC and salivary duct carcinoma. Thus, present study is aimed to compare the role of 68Ga-PSMA and 18F-FDG PET/CT in patients with primary and/or metastatic AdCC.

Decoding the Guidelines of Invasive Pulmonary Aspergillosis in Critical Care Setting: Imaging Perspective.

Invasive pulmonary aspergillosis (IPA) is a common, life-threatening opportunistic fungal infection seen in susceptible individuals especially those admitted in critical care units. Multiple guidelines have been promulgated for the diagnosis of IPA, some of which are all inclusive, while others cater to specific patient groups. Microbiology forms the crux of the majority of the diagnostic tests/criteria; however, results take a considerable amount of time.

Society of Chest Imaging and Interventions Consensus Guidelines for the Interventional Radiology Management of Hemoptysis.

The recommendations from the Society of Chest Imaging and Interventions expert group comprehensively cover all the aspects of management of hemoptysis, highlighting the role of diagnostic and interventional radiology. The diversity existing in etiopathology, imaging findings, and management of hemoptysis has been addressed. The management algorithm recommends the options for effective treatment while minimizing the chances of recurrence, based on the best evidence available and opinion from the experts.

Depth of Invasion in Carcinoma Tongue: Evaluation of Clinical and Imaging Techniques.

Background: "Depth of invasion" is an additional index incorporated in 8th AJCC staging system for oral cavity squamous cell carcinoma based on its prognostic significance. Pre-operative assessment by clinical palpation and imaging modalities has been used with limitations. The aim of the study is to compare different techniques including clinical palpation, ultrasound, and magnetic resonance imaging with histopathology for assessment of depth of tumor invasion.

Technical Report.

Diaphragmatic structure and function assessment can be performed using grayscale as well as M-mode ultrasound. This article discusses the application of M-mode ultrasound in the assessment of diaphragmatic dysfunction.

Plasma cells in oral lesion: A clue to diagnosis or a diagnostic dilemma.

Objective: Plasma cells can just represent a part of host inflammatory response or form the cornerstone of diagnosis such as IgG4-related disease (IgG4RD) and plasma cell dyscrasias and sometimes create a diagnostic dilemma. The study aims to discuss a series of plasma cell lesions which we encountered in the oral cavity, discuss the diagnostic conundrum of plasma cell lesions. We also propose a working classification for their interpretation.
