[Solitary eosinophilic granuloma of the orbit: a case report].

The authors report a case of eosinophilic granuloma involving the roof and the lateral wall of the left orbit in a 5-year-old boy. The clinical presentation and especially the imaging features (computed tomography and MRI) suggested a malignant tumor and the final diagnosis was obtained by fine needle aspiration biopsy with histopathologic examination. Despite its alarming radiologic appearance, there was spontaneous healing of the eosinophilic granuloma with restitution ad-integrum of the bone.

[Elastofibroma: imaging features].

Elastofibroma dorsi is a rare benign and slow growing fibro-proliferative lesion of unknown pathogenesis. It has a characteristic location (periscapular region) and a specific imaging appearance (songraphy, CT, MRI) allowing accurate prospective diagnosis. The recognition of this benign lesion avoids unnecessary biopsy and/or surgery. We report three cases of elastofibroma dorsi illustrating the characteristic features on sonography, CT and MRI. Involvement was bilateral in two cases.

[Neurosarcoidosis as the first manifestation of sarcoidosis: diagnosis difficulty. A case report].

Clinically apparent involvement of the nervous system occurs in a relatively small number of patients with sarcoidosis. The diagnosis of neurosarcoidosis is often difficult and particularly in patients who lack either pulmonary or systemic manifestations of sarcoidosis. Furthermore clinical and imaging features of neurosarcoidosis are extremely variable. We report a case of neurosarcoidosis which had been considered and treated at first as tuberculosis. Only the occurrence, two years later, of pulmonary manifestations of sarcoidosis enabled the diagnosis.

[Right tracheal bronchus associated with tuberculosis pneumonia. A case report].

Right tracheal bronchus is a rare almost always asymptotic congenital malformation. We report a case of right tracheal bronchus associated with pneumonia tuberculosis of the apical segment of the upper right lobe. We describe the characteristic of this malformation and stress the role of computed tomography scan to detect these anomalies.

[Primary lymphoma of bone: imaging features].

Primary lymphoma of bone (PLB) has benefited from recent advances in medical imaging and immunohistochemical study that are of prognostic and therapeutic value. From 3 case reports of PLB involving the iliac bone and the skull base, we review the definition of PLB and their main features. The importance of complete initial workup for staging in order to exclude secondary bone lymphomas, more frequent and of worse prognosis, is emphasized. Diagnosis of PLB involving the skull base is more difficult to obtain and nearly always requires neurosurgical biopsy unlike PLB of peripheral bones that are more readily amenable to percutaneous biopsy.

[Mucoepidermoid carcinoma appearing synchronously in the lacrimal and salivary glands].

An 86-year-old woman consulted for a swelling on the palpebral side of the upper eyelid that she had discovered 4 months earlier. Physical examination also revealed a parotid nodule on the same side. Clinical and radiological findings were in favor of a malignant lacrimal tumor. The parotid localization would correspond to either a lymph node metastasis or an intraparotid metastasis or to a primary parotid tumor with salivary metastasis; We discuss these hypotheses in light of the epidemiology, history and clinical and pathology findings.

[Post-traumatic adenoid cystic carcinoma of the lacrimal gland].

A young 17-year-old man was injured on the external orbital canthus and developed a tumefaction which remained stable. After 2 years the tumefaction with exophthalmia and visual troubles. Radiological investigations suggested two diagnosis: Organized hematoma or a lacrimal gland tumor. Surgical exploration found an apparently benign tumor but histologically it was a cystic adenoid carcinoma.

[Intraperitoneal vascular emergencies].

Intraperitoneal vascular lesions constitute severe causes of acute abdomen. These disorders include ischemia and infarction of colon and small bowel and abdominal hemorrhage. In case of intestinal ischemia, the radiologic procedures are performed in order to establish the diagnostic, identify the site of ischemia, and detect the etiology of ischemia. Plain radiography of the abdomen, ultrasonography, CT scan and angiography may be performed. In case of intestinal hemorrhage, angiography may be performed when endoscopy fails to establish the diagnosis. Embolization can be performed in selected cases.

[Subcapsular hematoma complicating acute pyelonephritis].

Spontaneous subcapsular renal hematoma is rare and essentially associated with malignant, or benign tumor vascular diseases, inflammatory processes. In few cases, no cause was detected. We observed one additional case in a diabetic women. She presented fever, and bilateral flank pain. Ultrasonography showed bilateral subcapsular hematoma. Computed tomography confirmed these findings and demonstrated multiple area of acute focal pyelonephritis.

[Value of imaging in the assessment of malignant fibrous histiocytoma of the soft tissues].

Malignant fibrous histiocytoma (MFH) is a rare and potentially highly malignant sarcoma. The authors report 6 cases of MFH in various sites: two in the chest wall, one in the pelvis, two in the gluteal zones and one on the scalp. Ultrasonography and computed tomography were the main imaging methods used in the assessment of the structure and extension of the tumor. A poor prognosis was noted in four cases: death within a few months in the two thoracic sites, recurrence in the pelvic and scalp lesions, radical surgery allowed recovery in two cases. A review of the literature showed that MRI and CT are complementary in the initial staging and follow-up of these patients.

[Craniofacial bone abnormalities in von Recklinghausen neurofibromatosis].

Cases of cranio-facial bone anomalies were observed in 40 cases of neurofibromatosis. The cranio-facial skeletal manifestations are numerous and varied. Radiographic investigation is important to confirm the diagnosis, when neurologic and cutaneous signs are absent. The diagnosis should be easily confirmed by a conventional radiographic study.

[Ultrasonographic aspects of kidney pelvis tumors associated with infectious hydronephrosis of lithiasic origin].

The ultrasonographic findings of 4 patients with surgically confirmed urothelial tumors associated with calculic pyonephrosis are presented. All the involved were markedly enlarged and hydronephrotic with obstructive calculi, stigmata of pyonephrosis and, an echoic pelvic mass, extending in calyceas in 2 cases. The sonographic appearance correlated well with the gross pathological findings. The histological types were 2 squamous cell carcinomas, 1 adeno-squamous cell carcinoma and 1 transitional carcinoma. The chronic calculic irritation was proved to induce squamous and glandular metaplasia. The subsequent squamous carcinoma and adenocarcinoma were documented in the literature. The preoperative diagnosis of the associated tumor was rarely done. The sonographic features reported are highly suggestive of urothelial tumor and may lead to an accurate preoperative diagnosis.

[Kidney carbuncle: diagnostic, bacteriological and therapeutic considerations. Apropos of 11 cases].

Renal carbuncle is a cortical lesion following bacteremia, occurring in patient without any urologic known problems. The analysis of 11 consecutive renal carbuncles showed that one should consider the diagnosis of renal carbuncle in young patients with flank pain, fever, and absence of significant leucocyturia. Our study confirms that renal carbuncle is always caused by staphylococcus aureus and that treatment is based on appropriate antibiotherapy. Isolation of the bacteria was difficult unless ponction of carbuncle under ultrasound control was performed. The usefulness of ultrasonography for the diagnosis of renal carbuncle and for its distinction from other suppurative renal lesions is emphasized.

[Infection and rupture of a serous renal cyst].

The authors report two cases of acute infection of a renal cyst with rupture into the urinary tract. The diagnosis was made by excretory urograms and ultrasonography. Differentiating a ruptured cyst from congenital caliceal diverticulum may sometimes be difficult. Antimicrobial treatment can control the infection and exclusion of the cyst was obtained in one case. The mechanism responsible for infection and rupture of the cyst are discussed, as well as the management of such cases.
