[Percutaneous drainagae of the secondary psoas abscess]

We report a series of 15 cases of secondary psoas abscess, showing its diagnostic and therapeutic difficulties aiming at evaluating the interest of precutaneous drainage role in its treatment. It is a monosentric retrospective study lasts for 5 years [January 2003- December 2007]. The study based on the clinical and operative reports, radiological and bacteriological findings. The study includes 15 cases aged 14 to 72 years old, the average was 31,4 years with slight male predominance 9 males to 6 females. Diagnosis has been done by the ultrasound and scanner examinations. 6 cases have [Crohm's disease, 3 retroc ecal apprendicitis, 2 tuberculous spondylitis 2 on top on colon tumors, 1 with diverticulitis and 1 post traumatic case. The most causative germes were gram-negative of digestive origin. In addition to the antibiotic treatment, 8 patients were operated from the start, 3 cases operated after a percutaneous drainage and 4 cases had a percutaneous drainage only which was effective. The secondary psoas abscesses are rare. As the clinical picture is less specific and hides the original pathology, which must be searched for and treated, diagnosis delayed. The most efficient treatment is the combined surgical and antibiotic one. The percutaneous drainage has its role in treating secondary psoas abscesses. At least it defers the surgical treatment to be done in better conditions latter on during the second step

[Hydatic cyst of the pancreas - a case report]

We report a new case of hydatid cyst of the pancreas. The diagnosis has been suspected on the radiological aspect then confirmed by serology. The treatment consisted in a resection of the prominent dome associated to drainage of the residual cavity. The post operative sequences were simple. To the light of this observation and data of the literature, the different clinical aspects, para clinical and therapeutic modalities of this very rare localization of hydatidosis are discussed
