Le syndrome de Poland est une malformation congénitale rare associant à des degrés divers des anomalies thoraciques et du membre supérieur homolatéral. Nous rapportons le cas d'une fillette de 7 ans, explorée pour dépression de l'hémithorax gauche avec masse sous claviculaire homolatérale. La tomodensitométrie a montré que la déformation de la paroi thoracique était liée à l'absence des chefs à insertion sterno-costale du muscle pectoralis major gauche avec agénésie du pectoralis minor et hypoplasie des arcs antérieurs des six premières côtes correspondantes. Ces anomalies étaient rapportées à un syndrome de Poland. Un bilan général fait d'échographie abdominale, radiographies des deux mains, a été réalisé chez la patiente n'ayant révélé aucune malformation associée. Le syndrome de Poland résulte d'un défaut d'approvisionnement sanguin des éléments musculosquelettiques de la paroi thoracique pendant la vie fœtale. Il existe de nombreuses variantes du syndrome de Poland qui peuvent être mieux détectées par la TDM qui doit être réalisée chaque fois qu'il est disponible, sans omettre le rôle de la radiologie général dans la détection des malformations associées. La caractéristique de ce syndrome est l'agénésie des faisceaux sternocostaux du muscle pectoralis major. Son étiologie reste inconnue et discutée. Une anomalie vasculaire en serait la cause, sans que le primum movens de cette anomalie vasculaire soit connu.

Intracranial meningiomas are benign extra-axial brain tumors. Their etiology is undetermined and several hypotheses have been proposed to explain their genesis. The clinical symptomatology of intracranial meningiomas is atypical and varies according to the location of the lesion, its size, and its relationship with neighboring organs. Imaging is essential for establishing a positive diagnosis, but the way to a diagnosis of certainty remains histological. In this article, we describe the CT and magnetic resonance imaging aspects of an intraosseous meningioma discovered in a patient in her forties that presented with right proptosis, and whose brain MRI revealed a cranial lesion with adjacent meningeal involvement; the CT scan subsequently performed allowed a better analysis of the bone lesion, the appearance of which suggested an intraosseous meningioma. This diagnosis was confirmed by a histological exam. The purpose of this article is to illustrate the CT and MRI aspects of this entity by reporting a case of intraosseous meningioma of spheno-orbital location.

Renal osteodystrophy is a common complication referring to the skeletal changes associated with the phosphocalcic disorders of chronic uremia in patients with end-stage kidney disease. Uremic leontiasis ossea (ULO) is a rare and severe form of renal osteodystrophy with characteristic overgrowth of the cranial vault and facial bones. Computed tomography (CT) findings are particularly characteristic and include serpiginous tunneling within the maxillofacial bones and cortical bone resorption. The recognition of its radiological appearance and abrupt management are essential to avoid its devastating esthetic and functional impairments. Today's better medical facilities have improved hemodialysis methods, and meticulous patient follow‐up has decreased the incidence of leontiasis. In this paper, we report three rare cases of patients with end stage renal failure who presented with multiple face swellings and were diagnosed with ULO.

Wernicke's encephalopathy is a pathological entity caused by Vitamin B1 (Thiamine) deficiency in malnourished individuals, especially alcoholics, patients operated for digestive surgery or suffering from gastrointestinal tract's diseases or incoercible vomiting. Classically it manifests by confusion with oculomotor disorders and ataxia. However, other neurological manifestations are possible. Magnetic resonance imaging is the gold standard imaging technique for diagnosis. It shows signal abnormality on periventricular area around the third and fourth ventricles and on mammillary bodies in the most common cases, however other localizations are possible, in particular the cerebral cortex, which can explain the occurrence of epileptic seizures in some patients. Early administration of Thiamine, intravenously or intramuscularly, allows ad-integrum recovery, while delayed treatment is associated with serious consequences in terms of mortality and morbidity with debilitating neurological sequelae. The presence of cortical lesions is of poor prognosis despite a well-managed treatment. In this article, we report a nonalcoholic Wernicke's encephalopathy case, following a subtotal gastrectomy. Epileptic seizures were the major clinical manifestation, related to the associated cortical lesions. Despite early and well-managed treatment, the patient had a poor prognosis, with progression, after one month, to a persistent chronic vegetative state.

Madura foot or pedal mycetoma is a chronic cutaneous fungal infection that is endemic in tropical countries but rare in temperate climates. If left untreated, this condition progresses to the destruction of soft tissues and adjacent bony structures with deformation of the affected limb, hence the importance of an early diagnosis. The aim of this work is to emphasize, through two cases of pedal damage observed in Morocco, the contribution of imaging in the diagnosis of this entity.
