Bilateral Anteriorly Displaced Microspherophakia in a Female Child With Marfanoid Habitus

Microspherophakia is a rare congenital anomaly characterized by an abnormally small and spherical crystalline lens, which can be associated with several systemic syndromes. We present an extremely rare case of bilateral anteriorly displaced microspherophakia in a female child with Marfanoid habitus. The patient displayed phenotypic features resembling Marfan syndrome, including tall stature, muscle hypotonia, dolichostenomelia, and increased arm span than body length. However, unlike Marfan syndrome, Marfanoid habitus is not associated with mutations in the fibrillin-1 gene. The association between microspherophakia and Marfanoid habitus is a unique presentation that has not been reported in the literature. This case report aims to increase awareness of microspherophakia as a possible ocular association of Marfanoid habitus.

Splenic Injury After a Colonoscopy: Threading the Scope Carefully in Heritable Connective Tissue Disorders

Colonoscopies have reduced colorectal cancer (CRC) burden in the United States, and their utility has expanded to include various diagnostic and therapeutic indications. Complications are seen in up to 1% and increase with age and polypectomy. As colonoscopies become widespread, specific populations seem to be at a much higher risk; notably patients with heritable connective tissue disorders (HCTD). As life expectancy increases, these patients undergo routine screenings and require careful peri-endoscopic care to reduce adverse outcomes. Amongst HCTD, Ehlers-Danlos syndrome (EDS) is commonly implicated, however, no reports of Marfan syndrome (MS) exist. We present a unique case of splenic injury after colonoscopy in a patient with MS. Successful outcomes require early suspicion and emergent surgical evaluation in patients with hemodynamic instability after a colonoscopy. Increased ligament laxity and bowel fragility are the most likely mechanisms. Alternative CRC strategies like fecal immunochemical test (FIT), fecal occult, Cologuard, or virtual colonography can be considered.

A Rare Case of Serratia marcescens Causing Mycotic Aneurysm and Septic Emboli in Intravenous Drug User

There are few literatures highlighting the presence of a mycotic aneurysm in the setting of bloodstream infection by Serratia. A 33-year-old male with a history of Marfan syndrome, mitral valve prolapse, and intravenous drug use (IVDU) presented to the ED with fever, nausea, and non-bloody emesis, and vague abdominal pain with concern for sepsis. With the strong association between IVDU and infective endocarditis, transthoracic and transesophageal echocardiograms were performed and were negative for vegetations. Abdominal CT and positron emission tomography (PET) scan were performed and revealed thrombosis at the first jejunal branch of the superior mesenteric artery (SMA), left renal pole infarct, and superior splenic pole infarct. Following CT angiography for potential thrombolysis, aneurysmal formation was discovered proximal to the filling defect within mid-SMA. Blood cultures drawn at presentation grew Serratia marcescens. The patient was treated with appropriate antibiotic, and recommended indefinite anticoagulation. The patient was then recommended to follow up with vascular surgery within two weeks for repeat abdominal CT angiogram.
