Abstract
A single common pulmonary vein is a rare anomaly, mostly occurring with asplenia. We wanted to report our case because it co-exists with polysplenia and ciliary dyskinesia.A baby girl about 2 months old with respiratory arrest was admitted to the emergency room of our hospital. She responded to pulmonary resuscitation. We ascertained from her medical history that she had been hospitalised twice because of recurrent lung infections. After the initial check and treatment, we applied imaging modalities to detect underlying problems of recurrent lung infection. Echocardiographic evaluation was suboptimal because of the widespread pulmonary infiltration. Still, we noticed a single common pulmonary vein without obstruction at the junction of the left atrium. Subsequently, a chest CT scan with contrast was performed. It revealed a single common pulmonary vein entering the left atrium with a single orifice, atrial septal defect, two lobes in both lungs, hepatic veins draining directly into the right atrium, and polysplenia. When the flow of a single common pulmonary vein goes directly to the right atrium through the defect, it may cause right heart dilatation as it did in our case. Therefore, patients may need to undergo surgery at an earlier age.

Abstract
This study describes the successful management of gangrenous pneumococcal infection in an infant with polysplenia, a rare congenital malformation characterized by multiple aberrant nodules of splenic tissue. The patient, a three-month-old girl with congenital heart defects and incomplete vaccination, presented with fever, irritability, and oxygen desaturation, followed by erythematous skin changes. The diagnosis revealed sepsis caused by Streptococcus pneumoniae, accompanied by extensive gangrenous skin lesions and signs of disseminated intravascular coagulation. Polysplenia was incidentally discovered during radiological investigation. Aggressive resuscitation measures and prolonged antibiotic administration led to significant improvement, including regression of skin lesions. This case emphasizes the importance of timely immunization and parental awareness for infants with spleen-related congenital malformations. Screening for undiagnosed malformative defects in congenital heart disease patients can aid in early detection and prevention of life-threatening complications. The successful management demonstrates the critical role of pediatric intensive care units in treating severe systemic infections.

Abstract
Agenesis of the dorsal pancreas is a rare congenital disorder with only a handful of cases described in the literature. It presents a diagnostic dilemma. Cross-sectional imaging is the cornerstone for diagnosis. It could have a syndromic association with polysplenia and cardiac anomalies. Pancreas divisum and chronic pancreatitis may present with similar symptoms and must be ruled out. We present a case of a 55-year-old male with recurrent non-specific abdominal pain and diabetes mellitus. He was managed with insulin and painkillers for symptomatic relief. We also reviewed approximately 68 cases described in the literature to date.

Abstract
Biliary atresia (BA) is a rare disease characterised by biliary obstruction of unknown origin that presents in the neonatal period. It is classified into syndromic with various congenital anomalies and non-syndromic (isolated anomaly). We present a case of syndromic BA associated with polysplenia and intestinal malrotation, discovered incidentally during the Kasai procedure. The small intestine was found to be non-rotated with the duodenojejunal junction to the right of the vertebral column. The presence of accessory spleens was noted. Kasai portoenterostomy and Ladd's procedure were performed. The patient had an uneventful postoperative course with the passage of cholic stool from the third postoperative day. At the seventh-month follow-up, the stool remained cholic. A multidisciplinary approach in the care of babies with BA and long-term follow-up is crucial for a successful outcome.

Diagnosis of Dextrocardia with a Pictorial Rendition of Terminology and Diagnosis. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9121977.

Abstract
A significant number of patients with dextrocardia and other cardiac malpositions have other congenital heart defects (CHDs). The incidence of CHDs in subjects with cardiac malpositions is significantly greater than that in normal children, and the prevalence varies with the associated visceroatrial situs. The most useful approach to diagnosis is segmental analysis. Firstly, dextroposition should be excluded. In segmental analysis, the visceroatrial situs, ventricular location, status of atrioventricular connections, the great artery relationship, and conotruncal relationship are determined with the use of electrocardiogram (ECG), chest X-ray, and echocardiographic studies, and, when necessary, other imaging studies, including angiography. Following identification of the afore-mentioned segments, the associated defects in the atrial and ventricular septae, valvar and vascular stenosis or atresia may be determined by a review of the historical information, physical examination, and analysis of chest roentgenogram, ECG, and echocardiographic studies. Along the way, a pictorial rendition of the terminology and diagnosis of cardiac malpositions is undertaken.

Abstract
Splenic torsion is an unusual condition that results in congenital abnormality, especially in the visceral abnormal arrangement. We report the case of an 8.5-year-old boy with features in the right upper quadrant. Radiological investigations revealed heterotaxy syndrome with polysplenia and a hypodense tumor in the right upper quadrant adjacent to several spleens. We initially treated it as an intra-abdominal tumor. Laparoscopy was performed to check the tumor condition and revealed a congestive tumor located in the abdomen of the right upper quadrant below the central liver, which was suspected to be a torsion spleen without attaching ligaments. Laparoscopic splenectomy was successfully carried out without complications. The pathological report shows splenic tissue with hemorrhagic infarction. Physicians should be vigilant of the differential diagnosis of the acute abdomen in adolescents.

Abstract
The infantile intestinal obstruction associated with situs inversus totalis and polysplenia is extremely rare, with only a few cases reported in the literature. Furthermore, the management of this association is complicated. We report a case of a 2-month-old boy with intestinal obstruction due to malrotation and volvulus with thin translucent omentum sac encasing the small intestine associated with situs inversus totalis, polysplenia, and pulmonary hypertension. To the best of our knowledge, this is the first case of situs inversus totalis with polysplenia, pulmonary hypertension, and intestinal obstruction due to malrotation and volvulus with thin translucent omentum sac encasing the small intestine.

Abstract
BACKGROUND Patients with heterotaxy syndromes (right and left atrial isomerism) are at high risk of poor outcomes after single-ventricle palliation. However, the long-term outcomes and specific parameters associated with poor outcomes are incompletely understood. METHODS A retrospective review was performed of all patients with atrial isomerism who had a Fontan at our institution from 1973 to 2020. Standard demographic, as well as pre-, peri-, and postoperative parameters were collected. Features and outcomes of patients with polysplenia were compared to asplenia. Outcomes were analyzed for effect during 4 eras: (1: 1973-1984; n = 27), (2: 1985-1994; n = 93), (3: 1995-2004; n = 28), and (4: 2005-2020; n = 10). RESULTS Of the 1176 patients who had a Fontan operation, 158 (14%) had a heterotaxy syndrome. The median age at the time of Fontan was 8 (9) years. Early mortality was 20% and was greater in patients with asplenia compared to polysplenia (27% vs. 12%, p = .019). But it substantially improved over time (61% in era 1 vs. 7%-10% in the more recent eras (p < .001)), as did transplant-free survival (22% at 10 years in era 1 vs. 88% in era 4, p < .001). Transplant-free survival was significantly lower in patients with asplenia versus those with polysplenia (p = .014), and patients with heterotaxy had lower survival than nonheterotaxy (p = .01). This was largely due to the asplenia group (p < .001) (hazard ratio = 3.05, p = .007). CONCLUSIONS After Fontan operation, patients with heterotaxy, particularly asplenia, continue to demonstrate worse transplant-free survival than nonheterotaxy patients. Early mortality and long-term transplant-free survival have improved in more recent eras.

Abstract
BACKGROUND AND AIM On the basis of previously published accounts, coupled with our own experience, we have assessed the surgical approaches to patients with isomeric atrial appendages. METHODS We reviewed pertinent published studies on surgical treatment of individuals with isomeric atrial appendages, with the pertinent surgical details provided by most of the manuscripts. RESULTS Half of patients with right isomerism, and two-thirds of those with left isomerism have bilateral superior caval veins. Azygos extension of the inferior caval vein is reported in three-quarters of those with left isomerism. The coronary sinus is universally absent in right isomerism, along with totally anomalous pulmonary venous connection, and is absent in two-fifths of those with left isomerism. Univentricular atrioventricular connections are expected in up to three-quarters of those with right isomerism. Atrioventricular septal defect is reported in up to four-fifths, more frequently in right isomerism, with such patients typically having discordant ventriculoatrial connections or double outlet right ventricle. Reported mortalities extend to 85% for those with right, and 50% for those with left isomerism. In right isomerism, mortality is up to 54% for systemic-to-pulmonary arterial shunting, up to 75% for univentricular repair, and up to 95% for repair of totally anomalous pulmonary venous connection itself. No more than one-quarter had undergone Fontan completion, with reported mortalities of 21%. CONCLUSION Early surgical results are satisfactory in patients with left isomerism, but disappointing for those with right. Recent advances in cardiac and liver transplantation may offer improved survival.

Abstract
Heterotaxy syndrome (HS) or situs ambiguous refers to the abnormal arrangement of viscera across the body axis, and abnormalities arise depending on the isomerism of the right or left atrial appendage. The cause remains unexplained and is attributed to a combination of genetic mutations and environmental factors. It is a rare condition and may remain undiagnosed for a long time. In this report, we aim to highlight an unusual presentation and aggravation of an infection due to the underlying isomerism of the left atrial appendage. We discuss the case of a female patient who presented with symptoms of fever and cough. The patient underwent prolonged antibiotic treatment, and her recovery was slow. The presence of bilobed lungs, vertical left-bronchus, and polysplenia on CT scan explained the left-sided aspiration pneumonia. The hypofunctioning spleen (polysplenia) caused her to have a weak immunological response, necessitating prolonged antibiotic use. She was followed up over time and had a recurrence of pneumonia within a few months. The condition is associated with high morbidity and mortality, and the role of early diagnosis and reporting to prevent complications is paramount. The recurrent pneumonia observed in the patient also raises questions related to long-term antibiotic use and immunization in the case of polysplenia in this patient population.

Abstract
Heterotaxy syndrome implies a discordance between placement of thoracic organs with respect to abdominal organs. A large number of these have associated congenital heart defects. This syndrome is unique as every patient is different and can have any permutation and combination of symptoms. In our case, the five-year-old male child presented with complaints of abdominal distension, fever, and bluish discoloration of limbs with even mild exertion. Radiological evaluation was diagnosed with a large atrial septal defect, cardiomegaly, partial pulmonary venous circulation, multiple small spleens on the right side of body, a large midline liver, malrotated bowel, inferiorly displaced kidneys, and two hemiazygos veins. The echocardiography and electrocardiogram too were consistent with atrial septal defect and right ventricular strain pattern. The reasons for this highly variable pattern are rooted in the genetically complicated process of lateralization with a strong link to the copy number variations. Due to the variable patterns, it is more efficient to report all the findings utilizing a step-by-step process of commenting on each and every individual organ, instead of classifying them under different categories based on atrial isomerism. This is important as any other way of classification predisposes to a certain bias.

Abstract
Background: Heterotaxy syndrome is associated with a plethora of cardiovascular and other multi-system anomalies with a high childhood mortality. A dilated azygos vein as part of the polysplenia variant of heterotaxy syndrome may cause oesophageal stenosis owing to a prolonged compression. We describe our technique of extramediastinal oesophago-oesophagostomy in the prone position for this rare congenital syndromic malformation with an excellent outcome. Patients and Methods: A 17-year-old boy with heterotaxy syndrome presented with intermittent dysphagia and postprandial emesis with failure to thrive. Despite the presence of diverse anatomic abnormalities, it was only his symptom of dysphagia due to oesophageal stricture that merited surgical intervention. He underwent an azygos-preserving extramediastinal oesophago-oesophagostomy in the prone position without segmental resection with the establishment of continuity using a modified Collard-type anastomosis. Results: The patient had an uneventful convalescence, with imaging after 1 year showing no re-stenosis. After a follow-up of 3 years, the patient is free of symptoms and has gained weight. Conclusion: Oesophageal stenosis may result from prolonged compression by anomalous vasculature. An isolated correctable anatomic derangement, young age with good functional reserve, other associated anomalies not causing any symptoms, the physiological advantages of executing the surgery in a prone position and availability of expertise in minimally invasive surgery ensured excellent outcomes. The hitherto unreported technique may open up avenues for further research regarding the behaviour of the oesophageal muscular tube with transection and re-anastomosis for rare benign abnormalities.

Abstract
BACKGROUND Heterotaxy syndrome (HS) is a condition in which the thoracoabdominal organs demonstrate an abnormal lateral arrangement and is often associated with congenital heart disease (CHD). Little is known about the adult HS population with CHD. OBJECTIVE To describe the outcomes and sociodemographics of the adult CHD population with HS. METHODS Records of patients 18 years of age or older with diagnoses of both CHD and HS at Texas Children's Hospital from 1964 to 2018 were reviewed. RESULTS Sixty-two patients met inclusion criteria. Median age was 22.7 [IQR 19.6-30.0] years; 26 (42%) were female; and 13 (21%) of patients had a gap in care of >3 years. Median follow-up time in adulthood was 2.9 [IQR 1.3-8.2] years. Forty-three (69%) of patients had single ventricle heart disease, 31 (71%) of whom completed Fontan circulation. A total of 36 interventions occurred in 24 patients which included 16 cardiac catherization interventions, 13 electrophysiology-related procedures, and 18 surgical procedures including 2 orthotopic heart transplants. The median age for death or heart transplant was 45.3 (95%CI 34.3-56.1) years. Heart failure-free survival was 80.8 ± 5.2%, 58.7 ± 11.0%, and 31.1 ± 15.7% at 20, 30, and 40 years old, respectively. Cerebrovascular accident-free survival was 84.3 ± 5.1%, 54.2 ± 11.3%, and 40.6 ± 14.5% at 20, 30, and 40 years old, respectively. Tachyarrhythmia-free survival was 54.0 ± 7.1%, 29.2 ± 8.3%, and 19.5 ± 9.7% at 20, 30, and 40 years old and bradyarrhythmia-free survival was 66.0 ± 6.3%, 41.7 ± 9.4%, and 33.4 ± 10.6% at ages 20, 30, and 40 years, respectively. CONCLUSIONS At a tertiary referral center, adult patients with CHD and HS have high rates of comorbidities and early death or heart transplant. Longitudinal surveillance and further exploration into factors associated with improved survival in this population are warranted.

Abstract
Gastric duplications are the least common gastrointestinal duplications, especially in adults. Duplication cyst with an accessory pancreatic lobe is extremely rare and is even more uncommon in the setting of polysplenia. No gastric duplication after partial gastrectomy has been reported. We present a 41-year-old male diagnosed with gastric duplications with an accessory pancreatic lobe and polysplenia. Another characteristic of this case is partial gastrectomy 20 years ago without the discovery of duplication cysts. The gastric duplications, accessory pancreatic lobe and accessory spleen were successfully resected.

Abstract
RATIONALE Heterotaxy with polysplenia is an extremely rare congenital condition resulting from abnormal arrangement of organs in the abdominal and thoracic cavities during embryologic development. When a malignancy such as pancreatic cancer develops under these conditions, surgical resection becomes particularly complex. This case report demonstrates successful pancreatic cancer resection despite the patient's complicated anatomy. PATIENT CONCERNS An 82-year-old female presented to our institution with complaints of mild right upper quadrant pain radiating to the mid-epigastric region. DIAGNOSES Physical examination revealed jaundice with scleral icterus consistent with obstructive jaundice. Radiographic imaging revealed hepatic duct dilation with several anatomic anomalies including small bowel location in the right upper abdomen, cecum, and appendix in the left lower quadrant, reversed superior mesenteric artery and superior mesenteric vein positions, and right-sided duodenal-jejunal flexture as well as an entirely right-sided pancreas, and left lower pelvis with ≥6 separate splenules. These findings resulted in a diagnosis of heterotaxy syndrome with polysplenia. INTERVENTIONS Careful preoperative planning and total pancreatectomy was performed without complication. OUTCOMES The patient recovered well. Pathologic examination of the pancreatic mass revealed moderately/poorly differentiated invasive pancreatic duct adenocarcinoma. The patient remains alive and well without signs of recurrent disease at the 2-year follow-up. LESSONS Given the wide range of anatomical variants observed in patients with heterotaxy syndrome, a thorough radiologic assessment is necessary before engaging in any surgical procedure. In our case, preoperative identification of the various anatomic anomalies, such as the short and vertically oriented pancreas, the porta hepatis position anterior to the duodenum, the nonrotation of the intestines and the anomalous origin of the right hepatic artery allowed us to perform a safe and uncomplicated total pancreatectomy.

Abstract
BACKGROUND "Heterotaxy syndrome", best segregated as isomerism, is characterised by laterality defects of the thoraco-abdominal organs, causing functional impairment. In particular, the spleen is frequently affected, increasing susceptibility to bacteraemia. This study explored factors that may increase the risk of bacteraemia in patients with isomerism. METHODS We identified patients with CHD and isomerism. Review of outpatient, inpatient, and surgical records was conducted to collect data and determine trends in the cohort. A Cox regression analysis was conducted to determine factors influencing freedom from bacteraemia (Fig 1). RESULTS We identified 83 patients with CHD and isomerism - 17 (20%) who had documented episodes of bacteraemia with a total of 21 episodes. A majority (86%) were nosocomial. The median age at the time of bacteraemia was 4 months. Although splenic anatomy did appear to influence the risk of bacteraemia in univariate analysis, this significance was lost with multivariate analysis. None of the other factors was significantly associated in either univariate or multivariate analysis. CONCLUSION Specific factors such as splenic anatomy, atrial appendage isomerism, and antibiotic prophylaxis status are not significantly associated with the risk of bacteraemia in patients with CHD and isomerism. Nosocomial infections represent a majority of bacteraemia in these patients.

46,XY disorders of sex development and congenital diaphragmatic hernia: a case with dysmorphic facies, truncus arteriosus, bifid thymus, gut malrotation, rhizomelia, and adactyly. Am J Med Genet A 2015; 167:1360-4.

Abstract
The association of 46,XY disorder of sex development (DSD) with congenital diaphragmatic hernia (CDH) is rare, but has been previously described with and without other congenital anomalies. Literature review identified five cases of 46,XY DSD associated with CDH and other congenital anomalies. These five cases share characteristics including CDH, 46,XY karyotype with external female appearing or ambiguous genitalia, cardiac anomalies, and decreased life span. The present case had novel features including truncus arteriosus, bifid thymus, gut malrotation, and limb anomalies consisting of rhizomelia and adactyly. With this case report, we present a review of the literature of cases of 46,XY DSD and CDH in association with multiple congenital abnormalities. This case may represent a unique syndrome of 46,XY DSD and diaphragmatic hernia or a more severe presentation of a syndrome represented in the previously reported cases.

Abstract
Limb body wall complex (LBWC) is characterized by multiple severe congenital malformations including an abdominal and/or thoracic wall defect covered by amnion, a short or absent umbilical cord with the placenta almost attached to the anterior fetal wall, intestinal malrotation, scoliosis, and lower extremity anomalies. There is no consensus about the etiology of LBWC and many cases with abnormal facial cleft do not meet the requirements for the true complex. We describe a series of four patients with LBWC and other malformations in an attempt to explain their etiology. There are several reports of fetuses with LBWC and absent gallbladder and one of our patients also had polysplenia. Absent gallbladder and polysplenia are associated with laterality genes including HOX, bFGF, transforming growth factor beta/activins/BMP4, WNT 1-8, and SHH. We postulate that this severe malformation may be due to abnormal genes involved in laterality and caudal development.

Abstract
Management of complex congenital heart disease in patients with Heterotaxy syndrome (HS) has steadily improved. However, there is an insufficient appreciation of various non-cardiac issues that might impact the overall status of these patients. This article briefly reviews the implications of gastrointestinal, immunologic, genitourinary, respiratory, and central nervous system involvement in HS patients with a view to aid in their comprehensive clinical management.

Abstract
Heterotaxy is a rare disease with high morbidity and mortality. Controversy exists over how to classify these syndromes with most cases stratified into asplenia/polysplenia syndromes or right/left isomerism. In an effort to review comprehensively specific pheonotypes associated with heterotaxy syndromes, we reviewed published cases series, adopted a classification scheme based on spleen status, and evaluated autopsy cases retrospectively with abnormal laterality at our institution. We categorized 116 cases as situs inversus totalis, polysplenia, asplenia, and single right-sided spleen. Cardiovascular abnormalities occurred in 87.1% of polysplenia, 90.5% of asplenia, and all cases of single right-sided spleen. For polysplenia, 48.9% had bilateral bilobed lungs, 87% had right-sided stomach, 58.1% had midline symmetric liver, and 60.4% had malrotated intestines. For asplenia, 51.9% had bilateral trilobed lungs, 86.7% had right-sided stomach, 45.8% had symmetric liver, and 65.5% had malrotated intestines. Atrioventricular septal defects occurred in 91.2% of asplenia compared to 56.8% of polysplenia cases. Eight percent had pulmonary/aortic stenosis or atresia. Double outlet right ventricle was more common in polysplenia (32.6%) compared to asplenia (21.4%). Total anomalous systemic venous return was described in 55.6% of polysplenia and total anomalous pulmonary venous connections in 81% of asplenia cases. Greater than half of the cases had no heterotaxy diagnosis. Although, we found similar heterotaxy-associated characteristics, the frequencies differed from previous studies. We found great variation in how heterotaxy-associated defects were described, diagnosed, and reported. Although there are known associated characteristics with the polysplenia/asplenia syndromes, correct identification requires a standardized approach for diagnosis and reporting.

Abstract
A 2-year-old boy with heterotaxy syndrome with associated polysplenia, ventricular septal defect, and malrotation of gut with volvulus is presented. There was delay in diagnosis due to the unusual plain abdominal radiography findings. At laparotomy, the midgut was also found to be enclosed in a thin transparent cocoon.

Abstract
According to The International Society for Nomenclature of Pediatric and Congenital Heart Disease (ISNPCHD), "Heterotaxy is synonymous with 'visceral heterotaxy' and 'heterotaxy syndrome'. Heterotaxy is defined as an abnormality where the internal thoraco-abdominal organs demonstrate abnormal arrangement across the left-right axis of the body. By convention, heterotaxy does not include patients with either the expected usual or normal arrangement of the internal organs along the left-right axis, also known as 'situs solitus', or patients with complete mirror-imaged arrangement of the internal organs along the left-right axis also known as `situs inversus'." or patients with complete mirror-image arrangement of the internal organs along the left-right axis, also known as situs inversus. The purpose of this article is to review the data about heterotaxy in the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database. The investigators examined all index operations in the STS Congenital Heart Surgery Database over 12 years from January 1, 1998 to December 31, 2009, inclusive. This analysis resulted in a cohort of 77 153 total index operations. Of these, 1505 operations (1.95%) were performed in patients with heterotaxy. Of the 1505 index operations performed in patients with heterotaxy, 1144 were in patients with asplenia and 361 were in patients with polysplenia. In every STS -EACTS Congenital Heart Surgery Mortality Category, discharge mortality is higher in patients with heterotaxy compared with patients without heterotaxy (EACTS = European Association for Cardio-Thoracic Surgery). Discharge mortality after systemic to pulmonary artery shunt is 6.6% in a cohort of all single-ventricle patients except those with heterotaxy, whereas it is 10.8% in single-ventricle patients with heterotaxy. Discharge mortality after Fontan is 1.8% in a cohort of all single-ventricle patients except those with heterotaxy, whereas it is 4.2% in single-ventricle patients with heterotaxy. The STS Congenital Heart Surgery Database is largest congenital heart surgery database in North America. This review of data from the STS Congenital Heart Surgery Database allows for unique documentation of practice patterns and outcomes. From this analysis, it is clear that heterotaxy is a challenging problem with increased discharge mortality in most subgroups.

Abstract
Isomerism or Heterotaxy syndromes are rare multifaceted congenital anomalies with multi-system involvement. Grouped under the broad category of Situs Ambiguous defects, these often pose diagnostic difficulties due to their varied and confusing anatomy. Since patients rarely survive into adulthood due to cardiovascular complications, the etiology and natural history of such conditions are not fully understood. Imaging provides the most accurate non invasive method for diagnosis and thereby, prognosis in such cases. We present a case of right sided Isomerism with complex cardiac anomalies in a 17 year old adolescent, who presented with dysphagia as one of the main complaints. Multi modality imaging demonstrated the intricate abnormalities in vital systems.

Abstract
We report the case of a 23 year-old obese female, with previously diagnosed situs inversus below the diaphragm, who presented with severe left upper quadrant abdominal pain. The patient was believed to have a surgical indication, possibly appendicitis or diverticulitis, and had an emergent abdominal Computed Tomography (CT) scan. The CT was interpreted as epiploic appendagitis with no signs of appendicitis. Epiploic appendagitis is a rare cause of acute abdominal pain, which involves the torsion and eventual necrosis of one of the epiploic appendages. This case was complicated by the fact that the patient had situs inversus below the diaphragm, which made it difficult to relate her localized abdominal pain to the correct anatomic area. The diagnosis allowed the patient to avoid invasive surgery and instead opt for conservative medical management. The utilization of radiologic imaging is of utmost importance in diagnosing this condition, which has characteristic findings on CT, US, and MR, all of which is discussed in this article.
