ABSTRACT

INTRODUCTION AND IMPORTANCE: Blunt abdominal trauma is one of the most common reasons for emergency department visits, and spleen and splenic vasculature is involved variably in those cases. Splenic artery pseudoaneurysm formation is one complication with potentially devastating consequences. Early detection and management are of paramount importance given its potential fatality. Management includes open repair with or without splenectomy, and endovascular approach. The minimally invasive endovascular treatment offers earlier recovery, preserved splenic function, and positive outcomes. We report a case of delayed presentation of a large splenic artery pseudoaneurysm after blunt abdominal trauma, managed using endovascular intervention. CASE PRESENTATION: A 45-year-old male presented 10 days after being involved in a pedestrian accident with blunt abdominal trauma resulting in a large splenic artery pseudoaneurysm. After multidisciplinary discussion, the decision was to take him for endovascular treatment. The patient recovered very well and was discharged two days later and followed up in an outpatient setting. Over a year, he became symptom free, and demonstrated radiological finding of shrinking pseudoaneurysm. CLINICAL DISCUSSION: Pseudoaneurysms of visceral arteries are repaired regardless of their size per society of vascular surgery guidelines. Larger ones are at higher risk of rupture and are associated with high mortality. When discovered, treatment plans should be readily discussed, and undertaken. In our case, the patient had a 6.5 cm splenic artery pseudoaneurysm, and a multidisciplinary meeting was conducted and concluded that endovascular treatment would be the best modality to start with, with surgical option as a backup in a hybrid room setting. CONCLUSION: Blunt abdominal trauma can present with overt symptoms of internal organ injury; however, some might be missed and need high index of suspicion and therefore further testing and imaging. Splenic artery pseudoaneurysms can expand and rupture in delayed presentation, early detection and management is of paramount importance. Endovascular treatment represents an excellent modality, with minimal invasive nature, faster recovery, and early return to daily activity with preserved splenic function.

ABSTRACT

In the present case, a 41-year-old male patient had reported a large swelling on the right side of his neck that had been radiographically diagnosed as a carotid body tumor. The tumor extended toward the right thyroid lobe, deep to the parapharyngeal space and cranially to the base of the skull. The clinical and medical imaging findings confirmed the diagnosis. Because of the large size of the tumor (50 mm × 48 mm × 85 mm), extent of involvement, and hypervascularity, surgical excision by midline mandibulotomy was chosen as the treatment approach. Midline mandibulotomy is a very good approach for large tumors with extensive involvement of the surrounding tissues, especially tumors with great medial and cephalic extension.

ABSTRACT

INTRODUCTION: Renal-caval Arterio-venous fistulas are rare entity which can be acquired, idiopathic or congenital. Laparoscopic cholecystectomy complicated by arteriovenous fistula formation is extremely rare and often go unnoticed. High output heart failure can occur as a consequence of such high flow fistulas. Repair can be done through open or endovascular approach with the latter being effective and less invasive. Repair can result in resolution of symptoms and improvement of heart function. CASE PRESENTATION: We report a 43-year old female who developed an iatrogenic renal-caval fistula following laparoscopic cholecystectomy, that was complicated by intraoperative bleeding. She presented with worsening high output cardiac failure a year post-operative. Due to past history of Cor-triatriatum surgical repair -a congenital heart disease-, the diagnosis of renal arteriovenous fistula remained insidious. The fistula was diagnosed during cardiac catheterization in an attempt to diagnose her rapidly decompensating heart failure, and repaired successfully by endovascular repair. DISCUSSION: To our knowledge, there are only a few reports in literature describing iatrogenic renal artery-caval fistulas in association with laparoscopic cholecystectomy. Such high flow fistulas can result in a significant, potentially life threatening physiologic impairment. The case was managed by endovascular approach resulting in return to baseline cardiac function and resolution of symptoms. CONCLUSIONS: Renocaval arteriovenous fistulas are extremely rare to complicate laparoscopic cholecystectomy. It might go unnoticed, but may present with decompensated heart failure. It can be reversed by early recognition of symptoms, and diagnosis. High index of suspicion is a key, and endovascular modality is excellent treatment approach.

ABSTRACT

INTRODUCTION AND IMPORTANCE: Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a poorly understood disorder which poses a diagnostic challenge to clinicians and pathologists. Here we have described the case of a male patient with IMHMV along with a presumed history of ulcerative colitis for 1 year. CASE PRESENTATION: A 55-year-old male presented to the OPD with history of chronic abdominal pain. Clinical and radiological examination coupled with endoscopic findings resulted in the patient being wrongly diagnosed to be a case of ulcerative colitis and was managed accordingly. Throughout his multiple hospital visits following treatment for ulcerative colitis, the patient was persistently symptomatic. He presented with 10 days history of increasing abdominal pain and constipation following which he developed spontaneous colonic perforation for which he underwent exploratory laparotomy left colectomy and Hartman's procedure. The final pathology of the resected colon found to be consistent of Idiopathic myointimal hyperplasia of the mesenteric veins and ischemic bowel changes. CLINICAL DISCUSSION: The absence of clear-cut endoscopic biopsy findings of ulcerative colitis made radiological picture to be the mainstay for diagnosis, which was inaccurate and exposed the patient to unnecessary treatment with immuno-modulators thus resulting in poor response to treatment. As the disease progressed, further narrowing of the vessels made the clinical picture to look closer to ischemic bowel pathology as the patient developed a top surgical emergency (i.e. bowel perforation). Such pathological finding (IMHMV) can only be diagnosed in a fully prepared tissue histology, but rather be considered when no other consistent alternative diagnosis was found. CONCLUSION: The treating physicians must definitely consider the possibility of idiopathic myointimal hyperplasia of mesenteric veins when similar manifestations are encountered in biopsy specimens of old cases with suspected inflammatory bowel disease or non-occlusive ischemia of the distal colorectum.

ABSTRACT

INTRODUCTION: Segmental aganglionosis (the absence of ganglions) is a rare presentation of Hirschsprung's disease, whereby only limited segment/segments of aganglionic bowel is interposed between segments of innervated bowel, or "skip'' area of normal innervations is present within an area of aganglionosis. PRESENTATION OF CASE: We reported a case of a 3 day old male newborn who presented with failure to pass meconium along with progressive abdominal distension. There were skip lesions present in between. Mikulicz double barrel enterostomy was carried out, which was followed by an uneventful postoperative period. Four months later, the patient was admitted for levelling biopsies which revealed the absence of ganglions in the terminal ileum as well as in the rectosigmoid junction. But the ganglions were present in between and proximal to the terminal ileum where the previously dilated small bowel segment was resected. This presentation was contradicted the most accepted migration theory of Hirschsprung's disease. DISCUSSION: As seen in our case, and in21 other cases published between 1954-2016, we highly recommend that leveling/mapping biopsies should definitely include the cecal pole and the small bowel segments proximal to the ileocecal valve as well as the multilevel colonic biopsies down till the rectum. CONCLUSION: Reporting of these cases brings out interesting questions with respect to the pathogenesis and serves to highlight the existence of several variants within the spectrum of Hirschsprung's disease.

ABSTRACT

BACKGROUND: Langerhans cell histiocytosis (LCH) is a rare clonal disease, characterized by hyperproliferation of Langerhans cells. It may rarely involve the thyroid gland. Its association with papillary thyroid carcinoma (PTC) is extremely rare; with only few case reports available in the English literature. BRAF mutations are implicated in the development of papillary thyroid carcinoma, and have also been identified in Langerhans cell histiocytosis. CASE PRESENTATION: Here we present a rare case of a 36-year-old Indonesian female patient with dysphagia associated with neck mass which was complicated by skin sinus formation. The diagnosis of PTC was rendered on fine needle aspiration (FNA). Debulking thyroidectomy revealed co-existeence of PTC and LCH. On subsequent molecular testing, BRAF V600E and V600K mutations were detected in tissues macrodissected from both lesions, respectively. To the best of our knowledge, this case is the first case to report two different BRAF mutations in tissues of a Langerhans cell histiocytosis and a papillary thyroid carcinoma co-existing in the thyroid gland. The patient received chemotherapy of etoposide combined with prednisone. At the most recent follow-up, the patient is in a stable clinical condition. CONCLUSIONS: The coexistence of a PTC with LCH harboring BRAF mutation may suggest etiologic relation between the two conditions that involves the BRAF gene. Clinically, it may suggest an aggressive, locally advanced thyroid cancer, an impression that may reflect on the selected surgical management, chemotherapy and BRAF mutation-targeting therapy to these patients.
