Visceral artery pseudoaneurysms is a known vascular complication of pancreatitis that can lead to life-threatening hemorrhages with a high mortality rate if left untreated. We present a case of ...ruptured gastroduodenal artery pseudoaneurysm in a 68-year-old male with acute pancreatitis presenting with fatal gastrointestinal and retroperitoneal bleeding that was successfully managed with endovascular coil embolization of the involved vasculature. Patients with hemorrhagic pancreatitis or those presenting with unexplained retroperitoneal or gastrointestinal bleeding in the setting of pancreatitis with an unexplained drop in hematocrit or sudden expansion of pancreatic fluid collection should be screened in a timely manner for pseudoaneurysm using CT angiogram of the abdomen, which is the gold standard imaging modality to identify pseudoaneurysms. Once pseudoaneurysm is diagnosed, it should be treated immediately. Endovascular treatment options are now favored over surgical options in most cases.
Gastrointestinal symptoms, especially diarrhea, are common with novel coronavirus SARS-CoV-2 infection. Angiotensin-converting enzyme-2 (ACE-2) receptors are heavily expressed in enterocytes and ...serve as entry receptors for SARS-CoV-2. ACE-2 receptors may also be responsible for pancreatic injury in patients infected with SARS-CoV-2. Diarrhea associated with SARS-CoV-2 is usually believed to be due to viral invasion of enterocytes. However, exocrine pancreatic insufficiency resulting from SARS-CoV-2 is another plausible mechanism leading to diarrhea in such patients. We present a case series of three SARS-CoV-2-infected patients with predominant respiratory symptoms at presentation who developed diarrhea, and further fecal analysis revealed exocrine pancreatic insufficiency as the underlying mechanism.
The incidence of venous thromboembolism (VTE), including lower extremity deep vein thrombosis (DVT) and pulmonary embolism (PE) is increasing. The increase in suspicion for VTE has lowered the ...threshold for performing imaging studies to confirm diagnosis of VTE. However, only 20% of suspected cases have a confirmed diagnosis of VTE. Development of pulmonary embolism rule-out criteria (PERC) and update in pre-test probability have changed the paradigm of ruling-out patient with low index of suspicion. The D-dimer test in conjunction to the pre-test probability has been utilized in VTE diagnosis. The age appropriate D-dimer cutoff and inclusion of YEARS algorithm (signs of the DVT, hemoptysis and whether PE is the likely diagnosis) for the D-dimer cutoff have been recent updates in the evaluation of suspected PE. Multi-detector computed tomography pulmonary angiography (CTPA) and compression ultrasound (CUS) are the preferred imaging modality to diagnose PE and DVT respectively. The VTE diagnostic algorithm do differ in pregnant individuals. The prerequisite of avoiding excessive radiation has recruited planar ventilation-perfusion (V/Q) scan as preferred in pregnant patients to evaluate for PE. The modification of CUS protocol with addition of the Valsalva maneuver should be performed while evaluating DVT in pregnant individual.
Gastrointestinal stromal tumors (GISTs) are the stromal or mesenchymal neoplasms affecting the gastrointestinal tract. Although they constitute 1% of primary gastrointestinal tumors, they are the ...most common nonepithelial tumors involving the gastrointestinal tract. They mostly present as overt or occult gastrointestinal bleeding. We present a case in which a 77-year-old female presented with a large abdominal mass. The origin of the mass was unclear on CT and MRI scan of the abdomen. Upper gastrointestinal endoscopic ultrasonography showed a cystic lesion in the perigastric region. A fine-needle biopsy of the lesion was performed, which was consistent with spindle type GIST. After the initial failure of imatinib therapy, the tumor was managed surgically.
Despite the increasing incidence of simultaneous mycobacterial and non-mycobacterial tuberculosis (TB) infection, little literature is available exploring the topic. Here, we present a case of a ...22-year-old female diagnosed with pulmonary TB for four months with simultaneous multiple sputum cultures positive for non-tuberculous mycobacteria (NTM). Computed tomography of the chest without contrast reported linear areas of scarring involving both lung apices, more prominent on the left side. The patient completed intensive phase treatment for TB and is currently on isoniazid and rifampin with a referral to an infectious disease specialist for recommendations on treatment of Mycobacterium avium regimen in view of azithromycin allergy (intense cough and rash). While the coexistence of NTM is commonly attributed to colonization, differentiating colonization from disease is crucial considering the long duration of treatment, potential drug toxicity, risk of drug resistance, and significant cost of treatment. Clinical, microbiological, and radiological evidence should be considered for diagnosis of TB and NTM coinfection and expert consultation should be sought in formulating the treatment plan.
Introduction . The occurrence of acute respiratory failure as a result of esophageal bezoars is a rare phenomenon. We present a patient who failed initial endoscopic intervention. Successful ...resolution was achieved through a novel approach involving a combination of Creon and Coca‐Cola. Subsequently, the patient was diagnosed with achalasia, a condition that potentially contributed to the formation of the esophageal bezoar. Case Description . An 82‐year‐old man presented with respiratory distress, necessitating endotracheal intubation for airway protection. A chest computed tomogram (CT) showed pneumonia and a distended esophagus compressing the trachea, raising the possibility of an esophageal food bolus. Endoscopy revealed a severely dilated esophagus containing a significant amount of food and a phytobezoar in the lower esophagus. He failed various endoscopic techniques to remove the obstruction. Given the patient’s poor surgical candidacy, he was started in a thrice‐daily regimen of Creon dissolved in 165 mL of Coca‐Cola, over a 4‐day period. A subsequent endoscopy revealed no discernible evidence of food or bezoar. The patient was weaned from mechanical ventilation. A high‐resolution esophageal manometry identified type 1 achalasia. Conclusion . Esophageal food impaction leading to respiratory failure is rare. Endoscopy remains the mainstay approach. Surgical interventions carry significant risks. This case emphasizes the potential for noninvasive management in patients with esophageal bezoars and also underscores the significance of contemplating esophageal pathologies when addressing cases of respiratory failure. The use of Coca‐Cola and Creon emerges as a safe, effective, and cost‐efficient treatment, providing a feasible option when endoscopy proves unsuccessful before considering more aggressive interventions.
Mycobacterium avium intracellulare (MAI) infections are common in Human Immuno-deficiency Virus (HIV) positive patients. MAI infection can have localized or disseminated presentation, patients with ...low CD4 count presenting with disseminated infection. Fever, abdominal pain, diarrhea, and weight loss are generally the presenting symptoms of disseminated MAI. We present a rare case of a patient with HIV and low CD4 count presenting with proctitis as manifestation of disseminated MAI infection. A 25 year-old-man with HIV came to the emergency room (ER) with complaints of intermittent rectal bleeding for two months. His CD4 count was less than 20 cells/µL. He was MSM (men having sex with men) and has receptive anal intercourse with men. His stool work-up was unrevealing for infectious etiology. Swabs for gonorrhea and chlamydia were negative. Colonoscopy revealed erythematous, congested, friable rectal mucosa with two superficial ulcers. Biopsies of the ulcer were positive for acid fast staining bacteria and the culture grew MAI. His blood culture was negative for growth of acid-fast bacteria (AFB). However, liver biopsy performed for elevated alkaline phosphatase of 958 units/L revealed noncaseating granuloma. Gastro-duodenoscopy with duodenal biopsy did not reveal any mucosal abnormality. He was managed as with disseminated MAI infection using clarithromycin, ethambutol, and rifabutin in addition to HAART therapy. Interval Colonoscopy in 20 months showed resolution of rectal ulcer. The gut is often involved in patients with disseminated MAI infection, with the duodenum being the most common site. MAI infection should be suspected as possible etiology for proctitis in HIV positive patient with low CD4 count, as proctitis, though infrequent can be the sole presentation for disseminated MAI infection in patients with HIV and low CD4 count.

Constipation is one of the most common functional gastrointestinal disorders and affects 20% of the general population. Irritable bowel syndrome (IBS) is a functional disorder of the gastrointestinal ...tract that affects the large intestine and is characterized by chronic abdominal pain and altered bowel habits. We report a case of a 35-year-old African American man with a past medical history of IBS who presented to the clinic with a chief complaint of abdominal pain and bloody diarrhea for 1 week. The patient stated that he used a colon-cleansing agent because of persistent constipation. Computed tomography scan of the patient’s abdomen and pelvis with contrast was performed which showed diffuse contiguous segmental mural thickening and nodularity seen along the distal transverse, descending, and sigmoid colon. Colonoscopy showed moderate diffuse inflammation characterized by altered vascularity, erythema, and granularity from the rectum to the descending colon, and localized mild inflammation characterized by erythema was found at the ileocecal valve. The patient’s clinical condition improved with symptomatic management over 10 days. Patients with IBS should be advised to restrain from using a colon-cleansing agent without advice from their primary doctor as it can lead to various complications.

Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is a rare, benign, focal, self-limiting disease. We report a unique case of KFD in a patient with coexisting ...Crohn’s disease. Our patient is a 23-year-old African American female with a past medical history significant for Crohn’s disease who presented to the clinic because of a painless lump over the right side of the neck for the past 3 weeks. On physical examination, the patient was found to have enlarged nontender right cervical lymph nodes from levels 2 to 4. An excisional biopsy of the right neck lymph node was done which revealed necrotizing histiocytic lymphadenitis, favoring a diagnosis of KFD. Over the course of the next 2 months, her lymphadenopathy got resolved. This is the first case of KFD in a patient with Crohn’s Disease. Lymphoma remains a feared adverse outcome for immunomodulatory drugs, thus necessitating their cessation upon signs of lymphadenopathy. Our case highlights the importance of a detailed workup in order to access the underlying cause of the lymphadenopathy so that the immunomodulatory drugs can be resumed in these patients.
