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.

Getting the diagnostic clue, role of MRI in the diagnosis of type 1 Glutaric aciduria in resource-limited settings.

Glutaric aciduria type 1 is a rare autosomal recessive disorder caused by a deficiency of glutaryl-CoA dehydrogenase, which is the key mitochondrial enzyme involved in the final degradation of lysine, L-hydroxylysine, and L-tryptophan. It is an inherited organic acidemia characterized by macrocephaly and dystonia, which results in high morbidity and mortality. In resource-limited countries like Nepal, where enzyme assays are not available, MRI has a great role to play in supporting diagnosis in such situations. Here, we present 2 cases of glutaric aciduria type 1 in brothers from the same parent that were diagnosed by MRI, and subsequent diet modification and L-carnitine therapy led to improvement of clinical symptoms.

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.

Ultrasound Guided Biopsy among Patients with Lung Lesions Undergoing Procedures in Interventional Radiology of a Tertiary Care Centre.

Introduction: Minimally invasive image-guided percutaneous core needle biopsy can obtain tissue samples for diagnosis of subpleural lung cancer, which is crucial for the correct management of lung lesions. Common complications of lung biopsy include pneumothorax, parenchymal haemorrhage and haemoptysis. The study aimed to determine the prevalence of ultrasound-guided biopsy among patients with lung lesions undergoing procedures in interventional radiology of a tertiary care centre. Methods: A descriptive cross-sectional study was performed in the Department of Radiology and Imaging from 1 August 2018 to 30 September 2019 after obtaining ethical approval from the Institutional Review Committee. USG-guided biopsy of peripheral lung lesions was performed with an 18 gauge semiautomatic biopsy instrument and a 17 gauge coaxial needle. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 188 biopsy of lung lesions, ultrasound-guided biopsies were performed in 28 (14.89%) (9.80-19.98, 95% Confidence Interval). Conclusions: The prevalence of ultrasound guided biopsy among lung lesions is lower than other studies done in similar settings. Keywords: biopsy; interventional radiology; lung neoplasms; prevalence.

Misty mesentery, ascites, and bowel wall thickening in a child: Diagnostic clue for intestinal lymphangiectasia.

Primary intestinal lymphangiectasia (PIL) is a rare congenital disorder characterized by lymphatic system obstruction, resulting in the leakage of lymph into the bowel lumen. We present the case of a 6-year-old boy with recurrent diarrhea and weight loss. On examination, bilateral pitting edema in the lower limbs was observed. Laboratory investigations revealed hypoalbuminemia and lymphopenia. Contrast-enhanced CT of the abdomen showed thickening of the jejunum, echogenic fat islands, and enlarged lymph nodes in the mesentery. The diagnosis was confirmed by endoscopic biopsy. The patient was managed with a high-protein diet and replacement of the long-chain triglycerides with medium-chain triglycerides. Gradual improvement in symptoms was observed with regular follow-up. PIL is a protein-losing enteropathy that causes hypoproteinemia, hypolymphopenia, and hypoglobulinemia. PIL usually presents with peripheral edema, weight loss, abdominal pain, and chronic diarrhea. Diagnosis is based on characteristic endoscopic and histopathologic findings. Management involves a multidisciplinary approach, including nutritional modifications, medical therapy, and, in rare cases, surgical resection. PIL remains a challenging diagnosis due to its nonspecific clinical presentation. Clinicians should maintain awareness of this disorder for prompt identification and management.

Not every twist is ovarian torsion: a case report of isolated torsion of the fallopian tube in a child.

Isolated fallopian tube torsion is a rare condition presenting with abdomen pain. The diagnosis is challenging because the clinical findings mimic several other conditions. In this article, we present a case of an adolescent girl who was diagnosed with the condition during laparoscopy. Presentation of the case: A 15-year-old girl presented with complaints of sudden onset left lower quadrant pain, nausea, and vomiting. There was tenderness in the left iliac fossa. Ultrasonography revealed inconclusive findings and contrast-enhanced computed tomography of the abdomen and pelvis suggested possible left adnexal torsion. Hence, she underwent a diagnostic laparoscopy which revealed a twisted, edematous, and congested left fallopian tube. The diagnosis of isolated left fallopian tube torsion was made and she was managed with unilateral salpingectomy. Discussion: Women of the reproductive age group are usually affected by this condition. The common presentations are abdominal pain, nausea, and vomiting. The physical examination may reveal abdominal and cervical motion tenderness. Per abdominal ultrasound is the first go-to modality in children. Magnetic resonance imaging, if available, is advised in children if the ultrasound is inconclusive because of the absence of radiation. However, it may require sedation. Therefore, contrast-enhanced computed tomography abdomen gives an added advantage in such scenarios as in our case. This condition is managed by surgery with salpingectomy or tube detorsion with preservation of the tube, depending on the intraoperative findings. Conclusion: Clinicians should be aware of the condition given the rarity and challenges in the diagnosis of isolated fallopian tube torsion.

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 Case of Multi-Drug Resistant Tubercular Pyomyositis in an Immunosuppressed Patient Presenting as Bacterial Infection.

Tubercular pyomyositis is a rare but distinct clinical entity which is difficult to diagnose especially in a patient with underlying autoimmune disease. The treatment is even more challenging if it is a multi-drug resistant strain. Here we report a patient with primary Sjögren's syndrome who presented with persistent inflammation of his right arm which was later diagnosed as multi-drug resistant tubercular pyomyositis. This case highlights the need for a high index of suspicion for tuberculosis in all cases of pyomyositis.

Intralobar pulmonary sequestration in 2 extremes of ages: A Case report.

Pulmonary sequestration is a relatively rare phenomenon characterized by nonfunctional lung tissue supplied by one or more systemic arteries without direct connection to the tracheobronchial tree. Intra-lobar pulmonary sequestration comprises 75% of the total pulmonary sequestrations. Most patients with pulmonary sequestrations are often diagnosed with a childhood chest infection, so pulmonary sequestration is considered a childhood disease. However, few cases are found in adults and the elderly, with or without symptoms, and imaging findings on computed tomography (CT) or magnetic resonance imaging (MRI) are variable due to infection and inflammation. Failure to diagnose and treat this condition may lead to recurrent pneumonia and fatal hemoptysis. In this case report, we present cases of pulmonary sequestration at extremes of ages, one at 12 and the other at 65.

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.

Late Presentation of Hypoxic Injury of Brain in an Infant.

Perinatal asphyxia is one of the leading causes of hypoxic-ischemic encephalopathy. In a developing country like Nepal, home delivery is the leading cause of perinatal asphyxia. Neuroimaging remains the diagnostic modality of choice. We present a case report of a 10-month-old infant who presented to the pediatric Out-patient-department with complaints of being unable to hold his head and unable to sit without support. Detailed history, physical examination, and developmental assessment along with lab investigation flash visual evoked potentials and Magnetic Resonance Imaging of the brain was performed. Hypoxic ischemic injury has common five types of imaging patterns in neonates. There are a few imaging differentials to be considered while evaluating the case for hypoxic injury. Clinicians and radiologists must go hand in hand to narrow down the possibilities which can fasten the treatment thereby decreasing morbidity and mortality. Keywords: Hypoxic ischemic encephalopathy, Infant, Magnetic Resonance Imaging.

Breakage of an orogastric tube in a critically Ill patient: a case report.

Orogastric and nasogastric tubes are common methods of enteral feeding. Although the methods of tube feeding are simple, these methods are not free of complications. Case presentation: This case report describes a 58-year-old patient with the diagnosis of stroke, in whom there was breakage of an orogastric tube during a prolonged ICU stay. Clinical discussion: Early enteral feeding in patients without any contraindications is associated with improved organ survival and recovery, and decreased incidence of infections, which decreases the ICU stay and improves the overall outcome. Nasogastric and orogastric tubes are the most commonly inserted feeding tubes. Breakage of an orogastric tube is a rare complication that can occur due to manufacturing defects, exposure to a harsh acidic environment, and forceful flushing of an obstructed tube. Conclusions: Timely identification of the broken feeding tube can help the treating clinicians retrieve it easily even with the help of a laryngoscope in selected patients.

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

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.

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 three­dimensional 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. Keywords: common bile duct; main pancreatic duct; magnetic resonance cholangiopancreatography.

Parasitic mature cystic ovarian teratoma: A rare case of autoimplantation of a twisted dermoid cyst.

Extragonadal parasitic dermoid cysts are rare. Diagnosis of such extragonadal parasitic teratoma is often done intraoperatively during surgical exploration of abdominal mass.

Surgical treatment of Candida albicans spondylodiscitis.

Introduction: Spinal infection poses a demanding diagnostic and treatment problem for which a multidisciplinary approach with spine surgeons, radiologists, and infectious disease specialists is required. Infections are usually caused by bacterial microorganisms, although fungal infections can also occur. Most patients with spinal infections diagnosed in the early stages can be successfully managed conservatively with antibiotics, bed rest, and spinal braces. In cases of gross or pending instability, progressive neurological deficits, failure of conservative treatment, spinal abscess formation, severe symptoms indicating sepsis, and failure of previous conservative treatment, surgical treatment is required. Case presentation: A 64-year-old male presented to the Outpatient Department with a complaint of pain in bilateral upper extremities for 4 months. The pain was shooting in type, radiating to bilateral arms, forearms, and hands with no aggravating and relieving factors. He is a known case of carcinoma pyriform sinus for which he underwent various cycles of chemotherapy. Ten years later, a tracheostomy was performed for laryngeal edema, and again, an endoscopic gastrostomy was performed due to feeding difficulties. He then developed fever and cervical pain along with pain in the bilateral upper extremities. An infectious etiology was suspected for which multiple antibiotics were started with no positive response. An MRI was performed, which was suggestive of spondylodiscitis probably of tubercular origin. A biopsy was done to confirm the diagnosis, following which antitubercular (HRZE) therapy was started. He was also treated with Duloxetine and gabapentin, which resulted in minor improvements. Subsequent MRIs showed diffuse involvement of the multiple cervical vertebrae along with cord compression. Two stages of anterior corpectomy followed by posterior instrumentation were done. Following the procedure, the patient developed an infection, which was managed with antibiotics. The titanium implant was not removed. A muscle graft was planned with the pectoralis muscle and flap closure was done. The tissue was also sent for Gram stain, AFB stain, and GeneXpert, which showed normal findings. Finally, in tissue culture, Candida albicans was isolated. On performing the enzyme immunoassay test, it was found to be Aspergillus (Galactomannan antigen) positive as well. Antitubercular treatment was stopped. Then, he was managed with an antifungal, oral voriconazole, for the duration of 1 and a half years. Clinical discussion: Patients diagnosed with Candida spondylodiscitis tend to have favorable outcomes, likely linked to timely identification, thorough surgical debridement, and proper azole medication. Our case achieved success by promptly identifying and confirming it through tissue culture, detecting spinal cord compression, decompressing it, and initiating specific antifungal treatment. A delay in commencing antifungal therapy has been associated with poorer outcomes, especially in neurological health. Our patient received voriconazole for a full year, suggesting that favorable outcomes are achievable for fungal spondylodiscitis with swift and appropriate surgery and antifungal medication. Conclusion: In summary, evaluation for fungal infection is essential in all cases of unexplained spinal infection in immunocompromised patients, regardless of presentation. If the antifungal treatment proves ineffective, a surgical approach is typically employed for the management of fungal spondylodiscitis. Our report details a successful case of fungal spondylodiscitis treated with a surgical approach and highlights the potential for a fungal infection to be a causative factor in noncompressive myelopathy, which may be sometimes mistaken for radiation myelitis.

Modern Paediatric Radiology: Meeting the Challenges in CT and MRI.

Radiology plays a very important part in the diagnosis, treatment, and follow-up of children. Computed tomography and magnetic resonance imaging are the two most crucial developments in the modern era. However, the two modalities have their challenges to overcome. Radiation dose is the most unwanted side effect of computed tomography scans while longer scan time along with sedation is a major disadvantage in children during magnetic resonance imaging. Paediatric-specific protocol selection and limiting the exposure to the area of interest aid in reducing the dose during computed tomography scans. Faster scan protocols and sequences can result in imaging without sedation in magnetic resonance imaging. Considering the radiation exposure, "as low as reasonably achievable" principle should be followed strictly in the paediatric population. In this article, possible ways for minimising the radiation dose in computed tomography, as well as effective, short, and sedation-free magnetic resonance imaging, are discussed. Keywords: computed X-ray tomography; magnetic resonance imaging; pediatrics; radiation exposure; X-ray.

Ruptured pulmonary hydatid cyst presenting as hemoptysis in TB endemic country: A case report.

Introduction: Hydatid disease is a major zoonotic disease. After the liver, the lungs are the common site of involvement. Clinical manifestations of the disease depend on the site and size of the cysts as well as the presence of complications. The majority of the cases remain asymptomatic. Complicated pulmonary cysts can present as chest pain, cough, shortness of breath, and hemoptysis. Sometimes, imaging is not sufficient for diagnosis and histopathological evaluation can provide the confirmatory diagnosis. Case presentation: A 32-year-old female presented with the complaints of episodic hemoptysis for the duration of two years. Radiological imaging could not provide a confirmatory diagnosis. Bronchoscopy was planned further. An endobronchial biopsy was taken for histopathological evaluation after seeing the whitish membranous structure within the right middle lobe bronchus. Hence, the diagnosis of ruptured cystic pulmonary hydatidosis was made. Clinical discussion: Echinococcus granulosus is the cause of cystic pulmonary hydatid disease which is transmitted through contamination by the infected definitive host, mostly dogs. Most cases remain asymptomatic for a long period. Hydatid disease has many clinical and radiological forms which should be recognized and included in the differential diagnosis of many pulmonary problems. Sometimes, imaging and serological studies may not confirm the diagnosis, histopathological evaluation may be required. Conclusion: Uncomplicated hydatid cysts are most commonly diagnosed incidentally in the adult population. Complicated hydatid cyst can present with various clinical manifestations. Episodic hemoptysis is one of the manifestations in our case. Clinicians should be aware of the typical as well as atypical manifestations of pulmonary hydatid disease.

Importance of clinical history in the diagnosis of psittacosis: A case report.

Introduction: Psittacosis, caused by the bacteria Chlamydia psittaci, is primarily a disease of birds that can be transmitted to humans. The clinical manifestations of the disease are wide, ranging from asymptomatic illness to fulminant psittacosis with multi-organ failure. The organism gets attached to the upper respiratory mucosa after inhalation and the majority remain asymptomatic. However, some people may develop symptoms of atypical pneumonia. Case presentation: Psittacosis usually presents with sudden onset fever with chills and rigor, headache, and myalgia. Here we present a case of a 35 years old female with a history of close contact with parrots who presented to the ER with complaints of high-grade fever and headache for 2 weeks which started 2 days after her parrots died. Discussion: The disease usually manifests as flu-like symptoms or pneumonia and is included in the differential diagnosis of community-acquired pneumonia. Investigations reveal neutrophilia, raised erythrocyte sedimentation rate, C-reactive protein, and elevated liver enzymes which were consistent with the findings of our patient. Chest X-ray showed ill-defined consolidation in the right middle and lower lobes which were inconclusive. Hence, a CT chest was done which revealed patchy ground glass opacities with surrounding consolidation giving a reverse halo sign. Due to her contact with birds and CT findings which were suggestive of psittacosis, she was started on doxycycline and her condition improved thereafter. Conclusion: We highlight the importance of proper history taking and awareness on zoonotic diseases to the general public to prevent, diagnose and treat the disease effectively.

A multidisciplinary approach to accidental inhalational ammonia injury: A case report.

Introduction: Ammonia is a highly toxic irritant gas, and its toxicity usually occurs from occupational exposure. Most are unintentional toxicity. It causes tissue damage via exothermic reaction with body tissues causing liquefactive necrosis. Presentation depends on the level and duration of exposure. Management is supportive and its antidote is not available yet. Presentation of case: We report a case of a 22-year-old male with accidental workplace exposure from coolant damage and leakage. He had altered mental status with visible injury to the nasal cavity, and ulcerated laryngeal mucosa with asymmetric vocal cords on bronchoscopy. Computed tomography showed right lower lobe consolidations. A muti-disciplinary approach and prompt management with respiratory support along with inhaled steroids and bronchodilators, antibiotics, electrolyte replacement, analgesics, and supportive eye and oral treatments were initiated. He had to be managed with a high-flow nasal cannula with subsequent tapering of the oxygen supplementation with titration. Discussion: Inhalation injury due to ammonia toxicity can have varied presentations from mild to severe life-threatening respiratory distress and neurological deterioration. Complications can range from upper airway edema to pulmonary edema. Most of these are usual findings except for the presence of pneumothorax. It could be due to the pre-existing lung status or oxygen therapy but the literature is inadequate. Conclusion: Ammonia inhalational injury may be associated with pneumothorax. It is important to have a multi-disciplinary approach and in-hospital management of ammonia toxicity as well as to raise awareness regarding the work environment and timely recognition of the possible occupational health hazards.
