RESUMO
This case report presents a rare case of peritoneal tuberculosis (TB) coexisting with a helminthic infection in a 25-year-old female residing in Australia, highlighting the diagnostic challenges posed by abdominal TB. Despite the low incidence of TB in Western countries, abdominal TB remains a diagnostic dilemma due to its nonspecific symptoms and potential mimicry of other abdominal pathologies. The case highlights the importance of considering TB as a differential diagnosis of unexplained abdominal symptoms, particularly in individuals with a history of travel or previous residence in high-endemic regions. A multidisciplinary approach involving infectious disease specialists, radiologists, and surgeons is essential for comprehensive management. Prompt initiation of anti-TB therapy is recommended once diagnosis is confirmed.
RESUMO
Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by gas-filled cysts that develop in the mucosal and submucosal layers of the digestive tract. PCI is typically a benign disease but complications can occur that require surgical intervention. This patient presented to the emergency department with a two-day history of abdominal and back pain. A contrast-enhanced computed tomography (CT) scan of the abdomen and pelvis led to suspicion of free intraperitoneal air potentially due to bowel perforation, and exploratory laparotomy was indicated. Bowel perforation was ruled out during the procedure, but outpouchings of air-filled cysts were found throughout the small bowel's external surface, leading to the diagnosis of PCI. Distinguishing free intraperitoneal air from PCI on imaging presents a challenge to clinicians. Contrast-enhanced abdominal CT is the preferred imaging modality, but PCI remains difficult to diagnose on imaging alone. Spreading awareness of the typical benign nature of PCI alongside the common presentation on imaging may lead to earlier detection, better treatment outcomes, and prevention of unnecessary surgical intervention.
RESUMO
The authors report on the case of a 69-year-old female who presented to the emergency department due to exquisite abdominal pain she described as occurring after she coughed. Imaging revealed a rectus sheath hematoma (RSH). A RSH is an uncommon but significant cause of acute abdominal pain that occurs when blood accumulates in the sheath of the rectus abdominis muscle. It can be caused by a muscular tear or a ruptured epigastric artery and can happen spontaneously or after trauma. The etiology, presentation, diagnosis, and management are discussed.
RESUMO
Omental infarction is an uncommon cause of abdominal pain. The condition is often misdiagnosed due to its clinical similarity to more common abdominal pathologies like appendicitis and cholecystitis. This report presents the case of a 57-year-old female with a one-week history of left-sided abdominal pain, initially aggravated by eating and defecation. The patient, a long-term smoker with a complex medical history that includes deep vein thrombosis and pulmonary embolism, was hemodynamically stable on presentation. A CT scan revealed a nodular infiltration consistent with an omental infarct. Conservative management was pursued, resulting in symptom resolution by the third day of hospitalization. This case underscores the diagnostic challenges associated with omental infarction, particularly its differentiation from other causes of acute abdominal pain. It highlights the importance of considering rare etiologies in patients with atypical presentations and emphasizes the role of imaging, particularly CT scans, in accurate diagnosis. The patient's successful conservative management aligns with current recommendations, which advocate for non-surgical treatment in most cases. This approach avoids unnecessary surgical interventions and ensures a favorable prognosis with low complication rates in patients with prompt and appropriate management.
RESUMO
Hereditary hemochromatosis (HH) is the most common autosomal recessive genetic disorder globally for Caucasians. HH is known as an iron metabolism disorder where there is an increase in iron absorption in the body. HH is not localized but a systemic disease; the manifestations of HH include cirrhosis, diabetes mellitus, cardiomyopathy, and pancreatitis. This case is about a 53-year-old female with a past medical history of heterozygous hereditary hemochromatosis who presents to the emergency department with abdominal pain, nausea, and vomiting and was found to have acute pancreatitis. This case report helps signify the importance of identifying and treating symptomatic heterozygous carriers of the HH gene mutation.
RESUMO
Neuroendocrine tumors (NETs) are rare cancers arising from neuroendocrine cells and are characterized by their ability to secrete functional hormones causing distinctive hormonal syndromes. The incidence of NET has increased over the years, and small bowel neuroendocrine tumor (SBNET) is one of the most challenging to detect due to its varied presentation and poor accessibility with traditional endoscopic methods. Patients with SBNET present with variable hormonal symptoms, such as diarrhea, flushing, and nonspecific abdominal pain, which often delay the diagnosis. We present the case of a young patient who underwent multidisciplinary workups leading to a successful diagnosis of SBNET promptly. The patient was a 31-year-old female who presented to the emergency department with complaints of nausea, vomiting, and sudden-onset, severe, sharp abdominal pain. CT scan of her abdomen showed an area of irregular intraluminal soft tissue density suspicious for a mass in the mid-small bowel. The patient's initial enteroscopy was normal. A video capsule endoscopy showed a small bowel mass, which was consistent with SBNET confirmed by pathology later. This case emphasizes the importance of considering SBNET as a differential diagnosis in young patients with nonspecific symptoms of abdominal pain and highlights the role of multidisciplinary approaches in achieving prompt diagnosis and treatment.
RESUMO
Appendagitis is an inflammation of the epiploic fringes, generally unrecognized by the clinician. It is responsible for abdominal pain and may mimic other causes of acute abdomen. It can be primary or secondary. In this article, we describe the first case of primary epiploic appendagitis in a renal transplant patient who consulted for left inguinoscrotal pain, which was diagnosed as primary epiploic appendagitis.
RESUMO
In the world of medicine and specifically endocrinology, hyponatremia is one of the commonest electrolyte abnormalities that result in a varied spectrum of presentations. Patients can incur symptoms ranging from lethargy, light-headedness, and confusion to much more severe symptoms such as vomiting, abdominal pain, deterioration in consciousness, and, in critical cases, even seizures. In elderly patients, hyponatremia is a major cause of Delirium and if not treated appropriately, can result in adverse outcomes and complications. In severe cases of hyponatremia, the opinion of an endocrinologist must be sought early for a conscientious investigation of the underlying etiology, as this prevents the need for unnecessary interventions, and thus reduces the risk of potential harm. Despite being a common electrolyte abnormality, hyponatremia can be associated with rare and uncommon etiologies, one of them being acute intermittent porphyria (AIP) as seen in our case. Due to the non-specific presentation of AIP, medical and healthcare professionals must be cautious of this condition, since it can mimic an acute abdomen. Symptoms of AIP usually overlap with other conditions, thus resulting in a diagnostic dilemma. Triggers and factors leading to acute attacks of AIP must be explored and rationalized appropriately, involving a thorough review of a patient's medication and social history. Moreover, discussion in a multidisciplinary team (MDT) setting for such complex presentations has a positive impact on patient care and is therefore recommended.
RESUMO
Breast cancer is one of the most commonly diagnosed cancers in Australia. With the development in screening, diagnosis, and treatment, people are living longer with metastatic disease of the breast. This malignancy commonly metastasizes to the lung, brain, bone, and liver. However, due to the increased survival of patients living with breast cancer, metastases may present with complications that have not been seen before. We describe a case of a 55-year-old female with a background of metastatic breast cancer to the brain who presented to the emergency department with acute appendicitis. At surgery, a malignant mass was found in the cecum obstructing the appendix, and histopathology revealed metastatic breast cancer.
RESUMO
Lupus enteritis is a poorly studied cause of abdominal pain in patients with systemic lupus erythematosus (SLE). We present the case of a 28-year-old female with a history of SLE for nine years. She has been on chronic immunosuppressant therapy for the last nine years due to an episode of lupus enteritis in the past. Currently, the patient presented to urgent care with a three-day history of waxing and waning symptoms of abdominal pain, vomiting, and diarrhea. In addition, the patient had skin rashes. Laboratory work was significant for leukopenia, hypocomplementemia, hematuria, and proteinuria. CT of the abdomen showed bowel thickening involving the entire ileum, distal jejunum, and first portion of the duodenum. It was accompanied by moderate mesenteric edema and a small amount of ascites. Since the patient was on long-term immunosuppressive therapy with hydroxychloroquine and mycophenolate mofetil, infectious etiology was of high consideration; however, it was ruled out after further testing. Along with continuing her home dose of mycophenolate mofetil and hydroxychloroquine, the patient was started on IV methylprednisolone 1 mg/kg for three days. The patient dramatically responded to IV steroids. The patient was transitioned to oral prednisone 60 mg daily, and steroids were tapered off by 10 mg each week. A repeat CT scan in two months showed the resolution of the previously visualized small bowel wall thickening. This case highlights that chronic immunosuppression should not preclude differential or diagnosis of lupus enteritis in a patient with a history of SLE.
RESUMO
Strongyloides stercoralis infection is usually acquired from tropics or subtropics, often causes asymptomatic chronic infection, but in immunosuppressed, it can lead to hyperinfection syndrome. We report a case of chronic abdominal pain resulting from Strongyloides infection in a 55-year-old male with a history of partial small bowel resection for small intestinal lymphoma and a recent diagnosis of chronic kidney disease with proteinuria on steroid therapy. He presented with chronic abdominal pain, nausea, loss of appetite, and weight loss. Initial laboratory workup and imaging including retroperitoneal ultrasound and CT of the abdomen/pelvis were within normal limits, and he was discharged on acid suppression therapy. He was readmitted with worsening symptoms and underwent esophagogastroduodenoscopy (EGD) and duodenal biopsy, which revealed Strongyloides infection. We later discovered a travel history to Cambodia. His symptoms resolved with ivermectin therapy. This case highlights the importance of travel history, which can prevent unnecessary investigations and delay in the diagnosis.
RESUMO
Acute epiploic appendagitis is a benign condition caused by inflammation of the epiploic appendages that are serosal lined outpouchings of the colon lying adjacent to the tenia coli. This rare condition has non-specific clinical findings and is frequently misdiagnosed as either acute diverticulitis or acute appendicitis. However, unlike other surgical causes of acute abdomen, epiploic appendagitis is a self-limited condition and resolves with conservative management. CT of the abdomen plays a vital role in diagnosing this condition and excluding other causes of acute abdomen. This case report highlights the importance of being aware of this rare condition and its consideration in the differential diagnosis of acute lower abdominal pain to avoid unnecessary hospitalization and surgery.
