The recycling of household waste through the anaerobic digestion of solid household waste into biogas represents one of the current topics that address the issues and environmental sustainability: renewable energy, depollution in urban ecology, methanogens in green chemistry. In this research, this contribution deals with the experimental digestion...

la dermatomyosite est une connective caractérisée par une inflammation du muscle squelettique associée à des manifestations cutanées caractéristiques. Leurs étiologies, encore méconnues, associent facteurs environnementaux et génétiques. Parmi les complications pulmonaires décrites, les pneumopathies interstitielles qui sont des complications fréqu...

Hydatid disease is endemic in certain areas of the world and it is located mostly in the liver. Intraperitoneal rupture is rare. Rupture may result from trauma or may occur spontaneously from increased pressure of the cystic fluid. Ruptured hydatid cyst is a rare cause of ascites, but should be considered in the differential diagnosis, especially i...

Meningioma rarely gives rise to metastases outside the brain and meninges. We report here a case of a patient who was treated for anaplastic brain meningioma with surgery and fractionated radiation therapy without any recurrence until 5 years after the operation, when she developed vertebral metastases.

Caseous calcification of the mitral annulus is a rare form of chronic degenerative process in the mitral valve fibrous ring with a mass-like appearance that has to be in the differential of the radiologist and cardiologist. We present the case of an 82-year-old woman in whom a tumor-like calcified mass in the posterior side of the mitral valve annu...

Periorbital dermoid cysts are benign tumors most often seen in young children. Intraorbital location, though rare, should not be overlooked. Good quality imaging plays a major role in the etiological diagnosis, providing a precise analysis of the location of the lesion, its components, and its effects on adjacent and nearby structures, as well as i...

Castleman disease (CD) is a benign angiofollicular lymph node hyperplasia usually found in the mediastinum, but the pelvis is rarely affected. Descriptions of the pelvic CD mainly involve computed tomography (CT) features and focal well-defined masses, while descriptions based on magnetic resonance imaging (MRI) patterns and infiltrating masses are...

Introduction: Aim : To evaluate the value of magnetic resonance imaging (MRI) in the diagnosis of 2 cases of epidermoid cysts.Materieal and Methods: 2 cases of histopathologically proven epidermoid cysts were studied. All patients were examined with conventional MRI (T1WI, T2WI, FLAIR) and Diffusion-weighted imaging (DWI).Results: the lesions were...

Nasofrontal fistulas, also called nasofrontal dermal sinuses, are very rare and found for the most part in children. This congenital malformation may be revealed by local infection or neuromeningitis, making this a serious disorder. We report one case of nasofrontal dermal sinus diagnosed in an 11-month-old girl, which was complicated by left front...

Les fistules naso-frontales, encore dites les sinus dermiques naso-frontaux, sont très rares et découvertes essentiellement chez les nourrissons et les jeunes enfants. Véritable porte d’entrée permanente, il peut être révélé par une infection loco-régionale et surtout neuroméningée qui fait toute la gravité de cette malformation congénitale. Nous r...

For a long time the imaging diagnosis of spine disease was based on conventional radiology (plain radiography, myelography and arteriography). The recent employment of MRI had changed the study of spine disease thanks to an excellent contrast and a multiplanar approache. In fact, nowadays MRI is the most sensible technic for a combined study of spi...

Inflammatory pseudotumors of the spleen (IPTS) are rare. We report a case of an IPTS in a 48-year-old woman who was admitted for drug eruption. During her hospitalization, she complained of abdominal pain. Physical examination and laboratory investigations were unremarkable. The abdominal ultrasonography and hepatic MRI detected a heterogeneous mas...

Geotrichum capitatum septicemias are rare, occurring exclusively in immunocompromised patients. We report a case of a 55-year-old man with acute myeloid leukemia who developed a G. capitatum septicemia with lung and skin lesions in the post chemotherapy aplasic phase. Treatment with amphotericin B (cumulative dose of 2 g) and maintenance with itrac...

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 examinat...

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 var...

Acute pancreatitis caused by hydatic cyst of the liver was rarely reported. The authors report a new case of hydatic pancreatitis characterized by visualization of hydatid membranes in the biliary tract without any biliary stone or alcoholic consumption.

Pelvic schwannoma (PS) is a rare benign tumor arising from schwann cells of peripheral nerve sheath. Ancient schwannoma is an exceptional histological subtype of typical schwannoma with degenerative findings. We report, to our knowledge, the third case of retroperitoneal ancient schwannoma occurred in a 23-years-old woman with pelvic pain and left...

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.

From a retrospective study carrying on 8 patients operated for sporadic parathyroid adenoma, we underline the place of medical imagery which allowed the detection of parathyroid adenoma in 7 cases. For all our patients the exploration of thyroid space was bilateral, seeking parathyroid glands. The authors discuss the stages and the various processe...

Primary renal non Hodgkin lymphoma is rare and unusual because the renal parenchyma does not have lymphatics. We report a case of bilateral primary lymphoblastic T lymphoma presenting with renal insufficiency in a 14 year old girl. We discuss clinical, pathological particularity and prognosis.

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 ord...

Invasive pulmonary aspergillosis (IPA) remains a life threatening complication in immuno-compromised and especially in neutropenic patients. We report our experience in the diagnosis and therapeutic management of IPA in 8 patients with acute leukemia.

Deep venous thrombosis (DVT) of upper limbs is extremely rare. DVT related to physical stress is a less known form. The purpose of this study was to outline the clinical pattern and laboratory features as well as the clinical course and outcome of this disease. The authors report 5 documented cases of upper limb DVT related to physical stress: 4 pa...

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 metas...

This retrospective study concerned 48 patients treated surgically for sub mandibular lithiasis. Results of medical imaging (plain films, sialography, ultrasonography) are confronted with operative findings. The surgical indications are analysed according to lithiasis localisation.

We report 2 cases of intra-osseous lipomas involving the right calcaneus in a 52 year-old male who consults for talalgia and the right ileum in a 28 year-old male who consults for buttock pain. Plain films suggested the diagnosis which was confirmed by computed tomography and Magnetic Resonance Imaging. Modern imaging techniques are very reliable f...
