RESUMEN
OBJECTIVE. The purpose of this study was to compare ultrasound and CT in the diagnostic evaluation of right upper quadrant pain in adults in the emergency department. MATERIALS AND METHODS. A retrospective review was conducted of adult emergency department encounters for right upper quadrant pain over a 5-year period, excluding those for prior cholecystectomy, current pregnancy, and trauma. Imaging study reports were reviewed for gallbladder and nongallbladder explanations of right upper quadrant pain and were considered positive for cholecystitis when two or more supportive features were present. Encounter outcomes were evaluated on the basis of pathology data and clinical management. RESULTS. Among the encounters, 2859 met the study inclusion criteria, and 18% met the study definition of cholecystitis by pathologic or clinical criteria. The following metrics showed no statistically significant difference between ultrasound and CT, respectively: sensitivity, 61% and 55%; specificity, 91% and 92%; positive predictive value, 63% and 63%; and negative predictive value, 91% and 90%. Both modalities were performed in 20% of encounters. In the subgroup analysis, ultrasound showed an acute nongallbladder abnormality that was missed at a preceding CT examination in only 1 of 238 cases (0.4%). CT showed an acute nongallbladder abnormality missed at a preceding ultrasound examination in 103 of 322 cases (32%). CONCLUSION. CT is noninferior to ultrasound in both ruling in and ruling out the diagnosis of cholecystitis in adult patients undergoing emergency evaluation of right upper quadrant pain and offers the advantage of depicting acute nongallbladder abnormalities.

BACKGROUND: Recurrent abdominal pain, particularly in the right upper quadrant (RUQ) in a patient with a history of cholecystectomy, known as postcholecystectomy syndrome, requires a broad differential diagnosis. Pathology of a retained gallbladder remnant is an exceedingly rare etiology of this pain. CASE REPORT: A 49-year-old woman who had previously undergone an open cholecystectomy presented to the emergency department with several hours of postprandial RUQ pain and emesis. Liver function tests and lipase were not significantly elevated. RUQ ultrasonography revealed a cystic structure containing a stone with mild prominence of the common bile duct at 7 mm, and magnetic resonance cholangiopancreatography confirmed the presence of a remnant gallbladder without common bile duct obstruction. Her pain subsided, she tolerated a diet, and was discharged with a referral for an elective cholecystectomy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Abdominal pain is the most common chief complaint of patients presenting to the emergency department in the United States, and emergency physicians routinely encounter patients with postcholecystectomy syndrome. Emergency physicians should not exclude the possibility of remnant gallbladder pathology, such as symptomatic cholelithiasis or cholecystitis, in patients presenting with symptoms concerning for biliary colic, even if the patient has undergone previous cholecystectomy.

Acute right upper quadrant (RUQ) pain is a common presenting symptom in emergency departments and outpatient medical practices, and is most commonly attributable to biliary and hepatic pathology. Ultrasound should be used as a first-line imaging modality for the diagnosis of gallstones and cholecystitis, as it allows the differentiation of medical and surgical causes of upper abdominal pathology, and in many circumstances is sufficient to guide patient management. Knowledge of strengths and limitations of ultrasound in the evaluation of RUQ is paramount in correct diagnosis. A spectrum of RUQ pathology for which a RUQ ultrasound examination should reasonably be considered as the initial imaging modality of choice will be reviewed.

Acute diverticulitis is a prevalent medical condition with increasing incidence rates. While the sigmoid colon is the most commonly affected part of the large intestine, there have been occurrences of right-sided diverticulitis although uncommon. We present a case report highlighting the atypical presentation of diverticulitis in a 27-year-old female patient. The patient experienced right upper and epigastric pain and was ultimately diagnosed with right-sided diverticulitis, supported by her CT imaging findings. This uncommon presentation underscores the importance of considering diverse clinical manifestations when diagnosing and managing diverticulitis.
RESUMEN
Acute cholecystitis (AC) and acute appendicitis (AA), independently, are among the most commonly diagnosed conditions in the emergency department (ED). However, their synchronous presentation is very rare. Here, we present a 31-year-old man with worsening right flank abdominal pain, nausea, and vomiting. Physical examination results were significant for moderate to severe right upper abdominal quadrant pain with a positive Murphy's sign and right lower quadrant pain with rebound. Workup in the ED revealed leukocytosis with a left shift, and the abdominal ultrasound and computerized tomography scan showed AA and AC. A literature review revealed a paucity of publications on concomitant AA and AC. Reporting new cases will contribute to improving our understanding of the biology, natural history, and management of this rare pathological combination.
RESUMEN
Introduction: Right upper quadrant pain is a very common symptom of cholecystitis. Right upper quadrant pain caused by fish bone perforation of the stomach wall is rare. Case Presentation: We report a 42-year-old woman who was admitted to our hospital with "1-month history of dull progressive right upper quadrant pain radiating to the back." Computed tomography of the abdomen revealed a linear, high-density body between the stomach wall and the liver. On history, the patient stated she had eaten a bony fish a month prior but did not note any significant pain at the time. Laparoscopy revealed a fish bone 2â cm in length half on the surface of the caudate lobe of the liver, and no perforation of the gastrointestinal tract was found. The postoperative course was uncomplicated, and the patient was discharged home on day 3 after surgery. Conclusion: The case of right upper quadrant pain caused by the fish bone is very rare. Radiological examinations play a significant role in the diagnosis of fish bone ingestion. Laparoscopic surgery is technically feasible and safe for the treatment of patients with fish bone ingestion.
RESUMEN
Tuberculous involvement of the spine (tuberculosis [TB] spine) can cause severe morbidity unless detected and treated early. Apart from the constitutional symptoms, it can present with back pain, kyphosis, gait abnormality, and paraplegia secondary to the bone or spinal cord involvement. There had been instances of TB spine presenting directly as abdominal pain due to psoas abscesses. Herein, we report a very rare clinical manifestation of TB spine as referred pain in the right upper abdominal quadrant due to right epidural phlegmon associated with T7 vertebra, detected by positron emission tomography.
RESUMEN
INTRODUCTION AND IMPORTANCE: Abdominal pain in the right upper quadrant is very common for patients to present in the emergency department. Finding the correct diagnosis seems straightforward in most cases but can be challenging. CASE PRESENTATION: We present the case of a 75-year-old male with a rare differential diagnosis for right upper quadrant and back pain, initially diagnosed as symptomatic cholelithiasis. After referral to an abdominal surgeon, detailed history taking prior to planned cholecystectomy revealed a record of back pain due to spinal degeneration and fusion surgery, as well as a bulb of the right abdominal wall with hypesthesia in a dermatomal area in the right upper quadrant. Considering these "new" facts, a spinal surgeon was consulted and a foraminal disc hernia of the thoracic vertebrae 11/12 was identified as the cause of symptoms. Instead of the initially planned cholecystectomy, a right-sided facetectomy Th11/12, sequestrectomy and unilateral transpedicular stabilization to decompress the nerve root was successfully performed. CLINICAL DISCUSSION: Although, symptomatic cholelithiasis is one of the most common diagnoses for patients presenting with right upper quadrant pain in the presence of gallstones, other differential diagnoses have to be considered. Thoracic disc herniations can present with atypical symptoms that mimic other non-spinal causes and may pose a diagnostic challenge, sometimes even leading to unnecessary surgery. CONCLUSION: This case highlights a rare differential diagnosis for one of the most common diseases seen by emergency physicians. It emphasizes the risk of working under time pressure, especially in an emergency setting, which may lead to premature diagnostic error and treatment, endangering patient's care and safety.
RESUMEN
The authors describe the case of a middle-aged female who presented to the emergency department with exquisite right upper quadrant pain. Computed tomography scan of the abdomen revealed a hydropic gallbladder, confirmed with abdominal ultrasonography. The clinical presentation, imaging findings, and management of this interesting condition are discussed.
RESUMEN
Diffusion weighted imaging (DWI) is a magnetic resonance imaging (MRI) non-contrast sequence that can indicate tissue ischemia or infarction. Adrenal infarct may present similarly to biliary or gallbladder pathologies, and the differential diagnosis during emergency work-up can be narrowed utilizing DWI sequences. In this paper, we describe the usefulness of DWI for urgent diagnosis in a case of non-hemorrhagic adrenal infarct of a pregnant female presenting with right upper quadrant pain. Although uncommon, adrenal infarct may occur in patients with hypercoagulability and localizing pain that is unexplained by other imaging modalities. We outline the imaging features of DWI in evaluating adrenal infarct as a safe and time effective application for patients with contraindications to imaging with ionizing radiation.
RESUMEN
Fitz-Hugh-Curtis syndrome (FHCS) is a rare complication of pelvic inflammatory disease. We report a case of a 21-year-old African American female presenting with inspiratory dyspnea and right upper quadrant pain found to be secondary to FHCS. The patient received antibiotic therapy, as well as testing of her sexual partners. This case demonstrates the importance of avoidance of biases such as anchoring, resulting in proper treatment and management of a rare disease entity.
RESUMEN
INTRODUCTION: Liver sarcoma is exceedingly rare and is a clinical challenge. CASE REPORT: A 69-year-old female presented with right upper quadrant pain after a fall. Her CT scan showed multiple cysts. She was initially diagnosed as hepatic cysts with hemorrhage and underwent puncture and drainage of liver cysts. But the cysts relapsed quickly. Then she underwent fenestration of the hepatic cysts. The liver cysts reoccurred again accompanied by massive bleeding and obstructive jaundice. She underwent right trihepatectomy and her final pathological report showed liver sarcoma. However, the hepatic sarcoma reoccurred again. Its' diagnosis and treatment process are extremely complex. In the end, she had a bad ending. CONCLUSION: We believe that timely diagnosis and complete excision of liver sarcoma are very important.
RESUMEN
Although right upper quadrant pain is a very common clinical presentation, it can be nonspecific. However, acute cholecystitis is very often the diagnosis of exclusion. This review focuses on the recommended imaging evaluation in the most commonly encountered clinical scenarios presenting with right upper quadrant abdominal pain, including suspected biliary disease, suspected acute cholecystitis, and suspected acalculous cholecystitis. This document hopes to clarify the appropriate utilization of the many imaging procedures that are available and commonly employed in these clinical settings. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

We present a rare case of giant adrenal pseudocyst as a cause of right upper quadrant (RUQ) pain and highlight the typical multimodality imaging features. The case demonstrates the imaging features associated with giant adrenal pseudocysts to aid accurate and timely diagnosis. Despite the rarity of these lesions they are important to consider as benign lesions can closely mimic malignant ones. Unenhanced and contrast-enhanced CT is the imaging of choice for adrenal cysts. However, MRI can provide more exquisite assessment of cystic, solid and enhancing components. Pseudocysts can be purely cystic, mixed or solid. Classically, adrenal pseudocysts are described as cystic lesions (of homogenous water density) with a fibrous wall and thin internal septations. Mural/septal calcification is commonly demonstrated due to haemorrhage, this is discernible from central/amorphous calcification seen in malignant disease. As in this case, pseudocysts can contain solid components or layering secondary to haemorrhage. The key to differentiating organised haematoma from tumour is the lack of enhancement. If serial imaging is undertaken in these patients rapid changes in the solid components may be seen reflecting resolving haematoma. Adrenal pseudocysts are rare and have a wide differential. Cystic adrenal lesions warrant multimodality assessment as their imaging features aid diagnosis and differentiation from malignant disease. We suggest that MRI plays a complimentary role to CT. CT is superior at demonstrating mural/septal calcification but MRI aids in determining cystic components and differentiating haemorrhage from tumour.

Fitz-Hugh-Curtis syndrome is a type of perihepatitis that causes liver capsular infection without infecting the hepatic parenchyma or pelvis. Fitz-Hugh-Curtis syndrome is known to occur commonly in women of childbearing age who do not use oral contraceptives and have sexual partners older than 25 years of age. However, the syndrome has been reported to occur rarely in males. The clinical symptoms are right upper quadrant pain and tenderness, and pleuritic right sided chest pain. The clinical presentation is similar in male and female. We experienced a case of Fitz-Hugh-Curtis syndrome in a 60-year-old man with the chief complaint of right upper quadrant abdominal pain. Despite a previous history of gonorrhea, we have also described our experiences of improved symptoms and recovery with allopathic medicines and have thereby reported the present case with a literature review.
RESUMEN
Spontaneous hemopneumothorax (SHP) is a rare potentially life-threatening condition that occurs in predominantly young adolescents. The resultant massive hemorrhage leading to hypovolemic shock can be a surgical emergency. It constitutes 1-12% of all spontaneous pneumothoraces and presents with two cardinal features, chest pain and dyspnea. However, the pain of SHP may be confined to the abdomen secondary to the irritation of diaphragmatic pleura, which produces signs simulating an acute abdomen. SHP masquerading as an abdominal affection is apparently regarded as extremely rare. We present a case of a 16-year-old male with SHP presenting features simulating acute gallbladder disease. After prompt diagnosis with appropriate surgical intervention, he had an uneventful recovery. Our experience emphasizes the importance of careful and thorough chest examination for each child with atypical pictures for abdominal pain to exclude possible extra-abdominal lesions, even rare as SHP.
