Computed tomography diagnosis of truncus arteriosus type IV: a case report

Truncus arteriosus (TA) is an uncommon congenital cardiac anomaly of which type IV is considered a rare variant. Recognition is crucial for proper treatment planning. The prognosis without treatment is poor. Echocardiography alone may not be useful in evaluation. Computed tomography (CT) finding is complicated. We report an 18 months child with ventricular septal defect (VSD), diagnosed on echocardiography, and further review by CT showed VSD with descending thoracic aorta giving rise to the pulmonary arteries suggestive of pseudo truncus (Collet and Edwards Truncus arteriosus Type IV) and right sided aortic arch with mirror image branching. Keywords: echocardiography, Collet and Edwards, computed tomography (CT), truncus arteriosus, ventricular septal defect (VSD

Abnormal Anatomic Variation of Pancreaticobiliary Union in Magnetic Resonance Cholangiopancreatography Department of Radiology and Imaging in a Tertiary Care Centre: A Descriptive Cross-sectional Study

Introduction: The knowledge of the variations of the abnormal anatomy of pancreaticobiliary union is of great importance for understanding various pathologies of the biliary tract, gall bladder, and pancreas as well as to avoid surgical complications and morbidity which may arise from pancreaticobiliary maljunction. Moreover, it helps in the early diagnosis and preventive treatment of pancreaticobiliary disease. The objective of this study was to find out the prevalence of abnormal anatomic variations of the pancreaticobiliary union in magnetic resonance cholangiopancreatography examinations. Methods: This descriptive cross-sectional study was done in patients referred for Magnetic resonance cholangiopancreatography examinations for various clinical indications from 1 February 2021 to 30 May 2021. Ethical approval was obtained from the Institutional Review Committee [Reference number: 306 (6-11)E 2 077/078]. The variations in the pancreaticobiliary union, length of the common channel, and angle between the common bile duct and major pancreatic duct were obtained from the 1.5T magnetic resonance scanner in 90 patients. The three‑dimensional magnetic resonance cholangiopancreaticography images were visually analyzed and classified into four categories. Convenience sampling method was used. Point estimate and 90% Confidence Interval were calculated. Results: Out of 90 patients, 73 (81.11%) (74.34-87.88, 90% Confidence Interval) patients had abnormal pancreaticobiliary union with pancreaticobiliary type as the most common occurrence seen in 33 (36.67%) patients. Conclusions: The prevalence of abnormal anatomic variation of pancreaticobiliary union was found to be higher than other studies done in similar settings

Susceptibility - weighted imaging: A valuable diagnostic tool for early detection of high-altitude cerebral edema: A case report

High altitude cerebral edema (HACE) is a clinical spectrum of high-altitude illness. The working diagnosis of HACE should be based on the history of rapid ascent with signs of encephalopathy. Magnetic resonance imaging (MRI) can be crucial in the timely diagnosis of the condition. A 38-year-old female was airlifted from Everest base camp due to sudden onset of vertigo and dizziness. She had no significant medical or surgical history, and routine laboratory tests showed normal results. MRI was performed, which showed no abnormalities except for the detection of subcortical white matter and corpus callosum hemorrhages on susceptibility-weighted imaging (SWI). The patient was hospitalized for 2 days and treated with dexamethasone and oxygen, and had a smooth recovery during follow-up. HACE is a serious and potentially life-threatening condition that can occur in individuals who rapidly ascend to high altitudes. MRI is a valuable diagnostic tool in the evaluation of early HACE, and can detect various abnormalities in the brain that may indicate the presence of HACE, including micro-hemorrhages. Micro-hemorrhages are tiny areas of bleeding in the brain that may not be visible on other MRI sequences but can be detected on SWI. Clinicians especially radiologists, should be aware of the importance of SWI in the diagnosis of HACE, and ensure that it is included in the standard MRI protocol for evaluating individuals with high altitude-related illnesses for early diagnosis and appropriate treatment to prevent further neurological damage and improve patient outcomes

A rare case report of patent vitellointestinal duct presenting as a periumbilical pain in an adult

The vitellointestinal duct (VID) is an embryological remnant of the vitelline duct, a structure that connects the developing fetus to the yolk sac and is responsible for the nutritional support of the fetus during the early embryological days. The VID usually gets obliterated by the fifth to ninth week of gestational age after the establishment of placental nutrition. The patent VIDellointestinal duct is a relatively rare congenital condition that occurs in approximately 2% of the general population, with the most common presentation being Meckel's diverticulum. Complete patency is rarer, occurring in 0.1% of the general population. The complete persistence of the VID results in enterocutaneous fistula, and the presentation may vary, ranging from cutaneous manifestations like skin lesions, granulomas, abscesses, or umbilical discharge to abdominal symptoms including acute abdominal pain and hematochezia. Some patients are even asymptomatic and are detected incidentally. We present a rare case of complete patency of the VID in a 30-year-old adult male presenting with acute periumbilical pain. Imaging findings guided the diagnosis, and surgical resection with histopathological examination further confirmed the condition

Multiple tracheobronchial diverticula in a post‐TB patient: A case report

Abstract The presence of multiple tracheal and bronchial diverticula is a rare condition. We present a case of a 22‐years old non‐smoker male with a history of pulmonary tuberculosis, having multiple tracheal and bronchial diverticula along with other common sequelae such as stenosed and collapsed upper lobe bronchi

Unilateral diaphragmatic palsy and pleuropericarditis in a patient with granulomatosis with polyangiitis: a case report

Abstract Background Granulomatosis with polyangiitis (GPA) is a rare small vessel vasculitis predominantly affecting upper and lower respiratory tract and kidneys. Unilateral diaphragmatic palsy could be a rare manifestation of GPA. Here we report a case of GPA in a 45-year-old male with unilateral diaphragmatic palsy with pleuropericarditis. Case presentation We report a case of a 45-year-old Khas male who presented with acute onset chest pain and shortness of breath who had elevated right hemidiaphragm, bilateral pleural effusion and pericardial effusion who was later diagnosed as GPA. Conclusions GPA should be suspected in all patients with diaphragmatic palsy and pleuropericarditis with appropriate clinical and laboratory picture

The double target sign as ultrasonographic finding in a case of double intussusception: A case report

Intussusception is one of the common conditions in children presenting with abdominal pain. The exact etiology of intussusception is unknown. Lead point is not identified in the majority of cases in children. Commonly, radiographic evidence suggests the presence of a target sign is diagnosis of intussusception. However, the presence of a double target sign in the case of intussusception is rare and depicts the presence of double intussusception. We present a case report of a 1-year-old child who presented to the emergency department with excessive crying for more than 10 hours. After the initial clinical assessment and acute management, an abdominal ultrasound revealed a double target sign on the sub-hepatic and left para-umbilical region which suggested double intussusception. No lead point was identified in our case. Early diagnosis and prompt treatment are the mainstay of management in such cases

Congenital pulmonary airway malformation (CPAM): A case report and review of the literature

Congenital pulmonary airway malformation (CPAM) is a rare congenital dysplastic malformation characterized by failure of bronchial development and localized glandular overgrowth. Previously known as Congenital Cystic Adenoid Malformation (CCAM), CPAM is classified into 5 types, from type 0 to type IV, depending upon the origin of pulmonary areas of the lung, cyst size, and cyst appearance. CPAM is a rare congenital anomaly typically diagnosed prenatally in ultrasound. However, few cases are diagnosed in childhood and even fewer in adulthood. CPAM can be differentiated from pulmonary sequestration based on the origin of the arterial supply; the former has its arterial supply from the pulmonary artery, whereas pulmonary sequestration has its arterial supply from the systemic circulation. Another differential diagnosis of CPAM includes congenital bronchogenic cyst, congenital lobar emphysema, pleuropulmonary blastoma, congenital cystic bronchiectasis, and congenital diaphragmatic hernia. The most common presentation is recurrent chest infection and chest pain, whereas other presentation includes pneumothorax and hemoptysis. Here, we present a case of a 6-year-old child with recurrent episodes of fever and cough diagnosed as a type II CPAM based on computed tomography findings
