At the Beach: To Jump or Not to Jump?

Splenic injury due to blunt abdominal trauma is an emergency condition in pediatrics. We present a case of a 10-year-old girl who presented to the emergency department 12 hours after a fall from height with abdominal pain, vomiting, and left upper quadrant tenderness and was found to have splenic rupture. Because of extensive bleeding and hemodynamic instability, emergency exploratory laparotomy was performed. Splenic bleeding lacerations were controlled by sutures and tamponade, and ipsilateral intrathoracic hemorrhagic fluid was drained with a good recovery. In this article, we emphasize the importance of early recognition, proper imaging, and splenic conservation where possible in pediatric blunt trauma.

Sarcoidosis in a 65-year-old woman presenting with a lung mass and pericardial effusion: a case report.

INTRODUCTION: Sarcoidosis is a multi-systemic disorder of unknown origin and most commonly affects the lungs. Diagnosis relies on the presence of non-caseating granulomas on histologic specimens. In high-resolution computed tomography, the most characteristic findings are peribronchovascular thickening, perilymphatic nodular distribution, and bilateral hilar adenopathy. Confluent nodular opacities or large masses are rare manifestations of the disease. It is well recognized that sarcoidosis can mimic infectious, malignant, and granulomatous conditions. Here, we report a case with a high initial index of suspicion for lung malignancy in terms of clinical, lung imaging, and endoscopic findings. CASE PRESENTATION: A 65-year-old Caucasian woman, lifelong non-smoker with an unremarkable medical history, presented with a 10-month history of progressive breathlessness, dry cough, fatigue, arthralgias, and mild weight loss. The only significant clinical finding was bilateral enlargement of auxiliary lymph nodes. High-resolution computed tomography revealed a soft tissue density mass at the right hilum which was surrounding and narrowing airways and vascular components, nodules with vascular distribution, enlarged mediastinal lymph nodes, and pericardial effusion. Our patient underwent a bronchoscopy, which revealed the presence of submucosal infiltration and narrowing of the right upper bronchus. Endobronchial biopsies showed non-caseating granulomas. As local sarcoid reactions with non-caseating granulomas can be observed near tumors, our patient underwent video-assisted thoracoscopy and surgical removal of an auxiliary lymph node, both of which confirmed the presence of non-caseating granulomas and the diagnosis of sarcoidosis. She was treated with steroids with improvement of clinical and imaging findings. However, while on a maintenance dose, she presented with a pleural effusion, which, after the diagnostic work-up, proved to be sarcoidosis-related. Treatment with initially high doses of steroids plus a steroid-sparing agent led to resolution of the effusion. CONCLUSIONS: We report a case with a high initial index of suspicion for lung malignancy. Clinicians should always be aware that sarcoidosis enters the differential diagnosis of patients presenting with a lung mass that encases and narrows bronchial and vascular structures with associated pericardial effusion. Rarely, pleural effusion can be the presenting symptom of disease relapse despite maintenance treatment.

Erdheim-Chester disease: pulmonary presentation in a case with advanced systemic involvement.

Erdheim-Chester disease (ECD) is a non-Langerhans cell histiocytosis usually affecting bone, that may progress to multi-organ involvement, with pulmonary involvement as an indicator of poor prognosis. Herein, we present a 48-year-old man with a 2-year history of progressive exertional dyspnoea, dry cough, malaise and exophthalmos. High-resolution computed tomography showed peripheral interstitial thickening with a lymphangitic distribution throughout both lungs, suspected of representing lymphangitic spread of neoplasia. Transbronchial biopsy specimen and bronchoalveolar lavage were non-diagnostic; thus, a surgical lung biopsy was performed which showed features diagnostic of ECD. Subsequent systematic investigations showed widespread bone involvement, cardiac involvement manifested as left heart failure and renal/perirenal disease. Treatment with pulsed corticosteroids and cyclophosphamide elicited neither clinical nor functional response, with death at 6 months. This case highlights the aggressive nature of ECD when there is pulmonary involvement, as well as problems in diagnosis when there is pulmonary presentation and when systemic disease is asymptomatic.
