RESUMEN
El absceso del músculo psoas ilíaco suele ser causa infrecuente de fiebre de origen desconocido en pacientes sanos. Sin embargo, su incidencia asciende en pacientes portadores de enfermedades debilitantes como la diabetes mellitus. Se presentó a una paciente diabética portadora de fiebre de origen desconocido, de seis meses de evolución, con diagnóstico final de absceso del psoas. La paciente, de 52 años de edad, ES portadora de diabetes mellitus tipo 1, complicada con uropatía litiásica obstructiva bilateral, infecciones urinarias a repetición, operada de pionefrosis y absceso renal derecho a los 33 años de edad, secundario a infección urinaria ascendente por Klebsiella pneumoniae. Se reintervinió por absceso recidivante a Klebsiella, adquirida por igual vía urinaria, pero esta vez con un absceso por contigüidad del músculo psoas ilíaco izquierdo, tras un período de fiebre de origen desconocido, de seis meses de evolución. La atipicidad de este caso radica en la recidiva de abscesos retroperitoneales profundos por Klebsiella y la forma insidiosa de presentación del actual absceso del psoas.
The abscess of the iliac psoas muscle uses to be the infrequent cause of unknown origin fever in healthy patients. Nevertheless, its incidence increases in patients who carry debilitating diseases as diabetes mellitus. The case presented deals with a female diabetic patient showing fiver of unknown origin already for six months, with final diagnosis of psoas abscess. The patient, aged 57 years, has type I diabetes mellitus, complicated with bilateral obstructive lithiasic uropathy and reiterative urinary infections. At the age of 33, she was operated of pyonephrosis and right renal abscess secondary to ascendant urinary infection by Klebsiella pneumoniae. She was operated again for recidivist abscess to Klebsiella, acquired through the urinary tract, but this time it was an abscess contiguous to left iliac psoas muscle, after a six-month evolution period of unknown origin fever. The unusualness of this case consists in the recidivism of deep retroperitoneal abscesses by Klebsiella and the insidious presentation form of the current psoas abscess.
RESUMEN
La arteritis de Takayasu es una arteritis inflamatoria crónica que afecta a grandes vasos, predomina en la aorta y sus ramas principales. Es una causa poco frecuente de fiebre de origen desconocido (FOD). Presentamos los casos de dos mujeres jóvenes hospitalizadas para el estudio de una FOD, en las que la aparición de amaurosis fugaz y de soplos supraclaviculares y carotídeos fueron las pistas clínicas que orientaron al diagnóstico. Este se confirmó a partir de la realización de ultrasonido doppler y angioTAC de troncos supraaórticos
Takayasu's arteritis is a chronic inflammatory arteritis involving the great vessels with predominance in aorta and its main branches. It is an infrequent cause of fever of unknown origin (FUO). Authors present the cases of two young women admitted for study of UOF in whom the appearance of fugax amaurosis and supraclavicular and carotid murmurs were the clinical clues directed the diagnosis. This was verified from a Doppler ultrasound (US) and angiographic CAT of supra-aortic trunks

Objective To investigate the causes and features of fever of unknown origin(FUO).Methods This study enrolled 89 patients who fullfilled the criteria of FUO and were admitted in China-Japan Friendship hospital from October 2005 to May 2008.Results The final diagnosis were made in 80 cases(89.9%).Etiologies of FUO were as follows:infections,41 cases(46.1%);rheumatic disease,15 cases(16.9%);neoplasm,18 cases(20.2%)(hematological malignancy,17 cases),miscellaneous diseases 6 cases(6.7%),unknown etiology,9 cases(10.1%).Conclusion Infection is the main cause of FUO;rheumatic disease and neoplasm are also important causes of FUO.Hematological malignancy is the most common neoplasm related to FUO.Detailed history contributes greatly to FUO diagnosis.
