While diarrhea, abdominal pain, and weight loss are hallmarks, atypical manifestations can obscure the diagnosis. This report highlights an unusual presentation of CD to emphasize the need for comprehensive diagnostic strategies. Case Report: A 25-year-old male presented with peripheral edema, anorexia, and abdominal distension but lacked classic gastrointestinal (GI) symptoms. Laboratory findings included microcytic anemia and hypoalbuminemia, while imaging revealed ascites and bowel wall thickening. Elevated fecal calprotectin and positive Anti-Saccharomyces cerevisiae antibodies (ASCA) supported the diagnosis. Endoscopy confirmed ileocolic Crohn’s Disease (L3 + L4). Infliximab therapy resulted in marked clinical improvement. Discussion: This case underscores the complexity of atypical CD presentations. Early use of serological markers, imaging, and endoscopy guided the diagnosis. Recognition of CD’s diverse manifestations is critical for timely intervention. Conclusion: Atypical CD presentations require heightened clinical suspicion and a multidisciplinary approach to reduce diagnostic delays and improve patient outcomes.展开更多

It has now spread to all parts of the world and as of 26<sup>th</sup> July 2020, more than 16 million cases and over 600,000 deaths have been reported. The commonest presentation is respiratory in nature with non-productive cough, fever and shortness of breath. Some COVID-19 patients have had atypical or unusual presentations involving the neurological, metabolic, gastrointestinal, renal, haematological, cutaneous and cardiovascular systems. In this mini-review, we have outlined the main atypical or unusual clinical presentations of COVID-19.展开更多

Usually, they present late in their disease with urinary tract obstruction, hematuria, bony pain, or cachexia because there is no screening program. Here we present a patient with prostatic cancer who presented with left axillary mass as his main concern. Case Description: 82-year-old Sudanese male presented with a left axillary and left supraclavicular lymphadenopathy of a few months’ duration. He underwent a decisional biopsy which showed metastatic adenocarcinoma. Upper and lower GI endoscopy were performed but the latter was complicated by a sigmoid perforation with peritonitis. During laparatomy, multiple enlarged pelvic lymphnodes were encountered and a biopsy result suggested a metastatic prostatic neoplasm. Later, prostatic biopsy confirmed the diagnosis. The patient was treated with bilateral orchidectomy. Clinical discussion: Lymphatic metastasis to axillary lymph nodes is a very rare manifestation of prostate cancer and only a few cases have been reported in the literature. It can cause diagnostic difficulty since prostate cancer typically metastasis to the pelvic lymph node and very rarely involves he supradiaphragmatic lymph node. Conclusion: Metastatic prostatic carcinoma should be considered among the causes of supra-diaphragmatic lymph adenopathy. Careful physical and imaging examinations combined with PSA and pathological analysis are essential in the diagnosis of advanced prostate cancer with unusual presentation.展开更多

In our case report, we discussed a rare presentation of CVST, a 16-year-old young boy who presented in emergency with history recurrent fall, weakness, tingling numbness. What makes it challenging to diagnose in his unusual presentation without common symptoms and on examination no positive neurological finding. This case brings focus on the importance of knowledge about CVST among emergency physicians. CSVT is considered more commonly as a differential diagnosis of stroke in young age group owning to genetic predisposition, hot humid climate of the state leading to severe dehydration, dietary factors leading to vitamin B12 deficiency & hyper-homocysteinemia etc. Moreover, present COVID-19, inducing a hypercoagulable state among affected individuals gave CVST a new momentous among emergency physicians. An early diagnosis can be very fruitful as it might prevent long term disability and reduce mortality significantly.展开更多

While in Maui, the patient presented with a fever and fatigue that resolved spontaneously. However, he had an observable rash on his head and was given a steroid injection to resolve the rash. Later on his trip, the patient experienced a dry, nonproductive cough which resolved with a five-day course of prednisone. While visiting Michigan, the patient began to experience neck pain and visited Troy Beaumont Hospital for further treatment. Meningitis tests were negative. Vancomycin was given due to the detection of gram positive coccidioidomycosis in the culture, but this was later proven to be a contaminant. Coccidiomycosis does not initially have specific symptoms. Despite negative coccidioidomycosis antigen tests, the patient exhibited features more consistent with blastomycosis and cryptococcus, highlighting the complexities of diagnosing fungal infections with atypical presentations. The case emphasizes the importance of considering alternative fungal pathogens native to endemic regions and pursuing comprehensive diagnostic measures to establish an accurate diagnosis. Lastly, the discussion about recommendations for antifungal therapy and preventative measures for individuals at risk of respiratory fungal infections is critically important for the advancement of early detection of fungal infections.展开更多

Although focal and scattered calcifications are not uncommon within the primary tumor mass, heavy calcification within a GIST is rarely described in the literature and the clinical-biological meaning of this feature remains unclear. Cases with such an atypical presentation are challenging and may be associated with diagnostic pitfalls. Herein, we report a gastric GIST with the unusual presentation of prominent calcifications that was identified incidentally on imaging during a post-trauma diagnostic work-up. The patient underwent laparoscopic surgery with a radical resection of the mass, which was subsequently characterized by histological analysis as spindle-shaped tumor cells, positive for CD117/c-KIT, CD34 and DOG1, and with calcified areas. Given the intermediate risk of recurrence, no adjuvant therapy was recommended andthe patient underwent regular follow-up for 22 mo, with no evidence of relapse. Our case can be considered of interest because of the rarity of clinical presentation and the uniquely large size of the GIST at diagnosis(longest diameter exceeding 9 cm). In closing, we discuss the pathophysiology and clinical implications of calcifications in GISTs by reviewing the most up-to-date relevant literature.展开更多

Older patients often present with subtle atypical manifestations, and failure to recognize these may lead to a cascade of negative events. Age-related immune system changes, comorbidities, and atypical presentations often make early diagnosis of COVID-19 difficult. Here, we report a case of an 82-year-old moderately frail male patient who presented with generalized body weakness and tested positive for COVID-19. On the second day of admission, he developed unilateral body weakness and aphasia, and computed tomography of the brain revealed acute right frontal spontaneous intracerebral hemorrhage with no vascular anomaly. He did not have any traditional risk factors for intracerebral hemorrhage and was not on any anticoagulants. The course of this case illustrates the delicate balance between the atypical presentations of COVID-19, the importance of a comprehensive geriatric assessment, and the management of older adults during the COVID-19 pandemic.展开更多
