Case Reports
Hydatid cyst, an unusual cause of spontaneous hemothorax and diagnostic thoracoscopy: case report.
Hydatid disease is a common parasitic disease in areas where sheep and cattle are raised and is currently endemic in the eastern and southwestern parts of Turkey. Patients with hydatid cysts typically present with cough, chest pain, dyspnea, hemoptysis, or allergic reactions. ⋯ Previously published series of cyst hydatid have reported cyst hydatid rupture and hemothorax secondary to trauma, but nontraumatic hemothorax due to spontaneous rupture of hydatid cyst has not been defined. We discuss the clinical features of a patient with no history of trauma who presented to the emergency department with hemoptysis and dyspnea and was found to have hemothorax due to spontaneous rupture of the hydatid cyst on videothoracoscopic investigation and underwent thoracotomy for hydatid disease treatment.

Fever of unknown origin (FUO) has been defined as a fever of ≥101°F that persists for 3 weeks or more. It is not readily diagnosed after 1 week of intensive in-hospital testing or after intensive outpatient or inpatient testing. Fevers of unknown origin may be caused by infectious diseases, malignancies, collagen vascular diseases, or a variety of miscellaneous disorders. The relative distribution of causes of FUOs is partly age-related. In the elderly, the preponderance of FUOs is attributable to neoplastic and infectious etiologies, whereas in children, collagen vascular diseases, neoplasms, and viral infectious disease predominate. The diagnostic approach to FUOs depends on a careful analysis of the history, physical findings, and laboratory tests. Most patients with FUOs exhibit localizing findings that should direct the diagnostic workup and limit diagnostic possibilities. The most perplexing causes of FUOs involve those without specific diagnostic tests, e.g., juvenile rheumatoid arthritis (JRA) or adult Still's disease. In a young adult with FUO, if all of the cardinal symptoms are present, JRA may present either a straightforward or an elusive diagnosis, if key findings are absent or if the diagnosis goes unsuspected. ⋯ Diagnostic fever curves are most helpful in cases where the diagnosis is most elusive, as was the case here. Relatively few disorders are associated with a double quotidian fever, ie, visceral leishmaniasis, mixed malarial infections, right-sided gonococcal acute bacterial endocarditis, and JRA. Because the patient received antipyretics during the first week of admission, fever was not present. After infectious disease consultation during week 2 of hospitalization, antipyretics were discontinued, and a double quotidian fever was present, which provided the key diagnostic clue in this case.
