A case of Tietze’s syndrome visualized on PET/CT-FDG

We report an interesting image of a 49-year-old woman revealed with Tietze’s syndrome (TS) by 18F-FDG PET/CT. She presented with right upper sternum pain with a hard and fixed palpable mass. Chest radiograph and CT-Scanner revealed no abnormalities. PET/CT-FDG showed a hypermetabolic activity around right sternoclavicular joint, which was the correct symptomatic lesion. Hence, FDG PET/CT may be useful for diagnosing TS and to accurately detect the symptomatic lesion

Les fracture-luxations transolécraniennes

Les fracture-luxations transolécraniennes sont une entité rare des fracture-luxations du coude. Il s'agit d'une lésion complexe qui peut compromettre le pronostic fonctionnel du coude. Dix patients étaient diagnostiqués dans notre service entre janvier 2005 et novembre 2012. Tous nos patients étaient de sexe masculin, l'âge moyen était de 29 ans. Les fractures de l'olécrane étaient complexes et comminutives dans sept cas et simples chez trois patients. Deux cas étaient associés à des fractures de la tête radiale (Mason III) et deux autres à des fractures de l'apophyse coronoïde. Les résultats étaient évalués après un recul moyen de trois ans et demi par le score de BROBERG et MORREY: trois cas étaient excellents, quatre bons, deux moyens et un mauvais. Cette lésion complexe nécessite une bonne reconstruction de la surface articulaire et une réparation des lésions associées pour permettre une rééducation précoce, seul garant d'une bonne  récupération fonctionnelle.Key words: Transolécranienne, fracture–luxation, Coude, olécran

Cardiac metastasis of lung cancer diagnosed by fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT)

Lung cancer is currently one of the most common malignancies worldwide. Among all metastatic sites of this cancer, cardiac metastases are exceptional, and long-term prognosis in these patients is very poor. 18F-FDG PET/CT is a valuable imaging tool for initial staging and assessment of treatment response of various neoplasms. In the case of lung cancer, its role is clearly defined, and its effectiveness is superior to other diagnostic imaging methods. We present a rare 18F-FDG PET/CT image finding in a 71-year-old man with biopsy-proven lung squamous cell carcinoma, showing increased cardiac 18F-FDG uptake subsequently found to be compatible cardiac metastasis

Neurolymphomatosis diagnosed on [18F]FDG PET/CT

Fluorine-18-deoxyglucose positron emission tomography/computed tomography ([18F]FDG PET/CT) has been shown to be superior to other conventional imaging modalities in the detection of extra-nodal lymphomatous localizations. Especially in neurolymphomatosis which is rarely encountered in high-grade lymphomas. We report a case of a woman diagnosed with non-Hodgkin lymphoma, whose initial staging with [18F]FDG PET/CT showed increased [18F]FDG uptake along the brachial and sacral plexuses. [18F]FDG PET/CT remains the most appropriate diagnostic tool in these cases, whose prognosis is often poor

Diabète insipide central : difficultés diagnostiques à propos de 3 cas.

Le diabète insipide central est une pathologie rare. Il est caractérisé par un syndrome polyuropolydipsique de sévérité variable secondaire à un déficit en hormone antidiurétique (ADH). Le diabète insipide central relève de causes multiples, nécessitant une enquête étiologique minutieuse. A travers le cas de 3 patients, consultant pour un syndrome polyuro-polydipsique, nous discuterons des difficultés diagnostiques rencontrées et nous insisterons sur les particularités de l’enquête étiologique et sur la nécessité d’un suivi clinique et radiologique à long terme des patients présentant un DIC d’étiologie indéterminée

Unusual pathological fracture of the clavicle revealing primary hyperparathyroidism: a case report

Abstract Background Primary hyperparathyroidism revealed by a pathological fracture is very uncommon; in the majority of cases the discovery of lytic bone lesions on imaging examinations evokes in the clinician first a neoplastic etiology and a metabolic origin is often omitted. This case report adds to the existing literature as it describes an unusual presentation of primary hyperparathyroidism. Case presentation We report a case of a 50-year-old Moroccan man, without any known tumor, who presented a fracture of his left clavicle with multiple osteolytic lesions on computed tomography suggesting bone metastases. However, bone scintigraphy oriented the diagnosis to a metabolic pathology by showing a metabolic bone “super scan” with increased tracer uptake in the left clavicle; parathyroid scintigraphy was able to localize pathological right parathyroid tissue. Conclusions Whenever multiple osteolytic lesions are found in a patient without any known tumor, metabolic bone diseases including hyperparathyroidism should be highly considered

Unusual finding of bronchopulmonary carcinoma through a pterygoid muscle metastasis. About a case

Bronchopulmonary cancer muscle metastases are uncommon, especially when they are visible. They can impact any muscle in the body, but the psoas, diaphragmatic, and paravertebral muscles have a clear advantage. We present a case of lateral pterygoid muscle metastasis of squamous cell carcinoma of the lung in a 70-year-old habitual smoker (40 packs per year) presents headaches more marked on the right and progressively worsening. A complementary brain MRI revealed a well-limited oval formation with irregular contours in hypo signal T1 hyper signal T2 heterogeneous, with area of central necrosis of the right pterygoid muscle, which was revealed to be a secondary location of bronchopulmonary malignancy after further examination (CT scan of the cervico-thoraco-abdomino-pelvic region, TEP scan, and biopsy). Moreover, muscle metastases are rarely revealing of primary cancer
