Radiologic findings of thoracic scoliosis due to giant ganglioneuroma

A 28-year-old male with scoliosis presented with complaints of dyspnea and vomiting. His medical history revealed a mediastinal ganglioneuroma resection at the age of 2. After the surgery, he had not been followed up until his admission to our hospital. Computed tomography and MRI showed severe scoliosis of the thoracic spine and a paravertebral mass extending from the upper thoracic level to the level of renal arteries. Based on its radiological findings and the patients history, the tumor was considered to be a recurrent ganglioneuroma. Paravertebral ganglioneuromas may cause progressive scoliosis, and a careful examination for patients with progressive scoliosis is mandatory.

Incomplete left-hand and complete right-hand pisiform and hamate coalition: multidetector computed tomography findings.

Pisiform-hamate coalition is a rare form of carpal coalition. Only 14 cases of pisiform-hamate coalition have been reported in the English-language literature. We present a case of asymptomatic bilateral pisiform-hamate coalition in a 16-year-old boy. We also review the embryology, pathogenesis, and clinical features of pisiform and hamate coalition, along with the associated multidetector computed tomography findings.

Pterygopalatine Fossa: Not a Mystery!

The pterygopalatine fossa is an important anatomic crossroads that is connected with numerous intra- and extracranial spaces via foramina and fissures. Although this fossa is small, its central location in the skull base and its communications provide clinical, radiological, and anatomical significance. In this pictorial review, we aimed to describe the radiologic anatomy of the pterygopalatine fossa, as well as to give some pathologic examples to better understand this major conduit.

Effect of teriparatide treatment on endothelial function, glucose metabolism and inflammation markers in patients with postmenopausal osteoporosis

Teriparatide, an anabolic agent used in the treatment of postmenopausal osteoporosis, can induce effects similar to primary hyperparathyroidism. Our objective was to evaluate the effects of teriparatide on endothelial functions, glucose metabolism and inflammation markers in patients diagnosed with postmenopausal osteoporosis.

Imaging features of Burkitt lymphoma in pediatric patients

Burkitt lymphoma is an aggressive and rapidly growing tumor that is curable and highly sensitive to chemotherapy. It can affect almost every tissue in the body, producing various clinical presentations and imaging appearances, according to the predilection of the different subtypes for certain sites. Awareness of its diagnostically specific imaging appearances plays an important role in rapid detection and treatment. In this pictorial review, we aimed to identify the most common imaging features of Burkitt lymphoma in pediatric patients.

MRI and CT findings of isolated intracranial Rosai–Dorfman disease in a child

Isolated intracranial Rosai–Dorfman disease (RDD) is extremely rare in pediatric patients. We present the case of a 22-month-old boy whom had isolated intracranial RDD involvement. To our knowledge, a parieto-occipital regional involvement without a dural tail sign has not been previously documented. Also, the mass contained hyperintense central T1 foci, and hypointense T2 and gradient echo foci; which are helpful in the differential diagnosis from meningioma. The magnetic resonance and computed tomography imaging findings are discussed and the follow-up course is presented in this paper.

Juvenile Nasopharyngeal Angiofibroma: Magnetic Resonance Imaging Findings

Purpose: Juvenile nasopharyngeal angiofibroma (JNA) is a rare tumor that exhibits a predictable spreading pattern. Radiologist’s prior knowledge on the tumor’s characteristics aids in establishing a diagnosis. We aimed to report the characteristic Magnetic Resonance Imaging (MRI) findings and the spread patterns of JNA. Materials and methods: We retrospectively evaluated the MRI findings and extension pathways of 6 cases of JNA. Results: The patients’ age ranged from 8 to 16 years and all patients were male. The tumors were classified according to the Onerci system. Tumors were largely isointense to muscle on T1-weighted images and hyperintense on T2-weighted images. All lesions had internal signal-void regions and all exhibited intense enhancement after IV contrast injection. Diffusion restriction was not an associated feature. ADC values for these tumors were high. The evaluation of the available MR angiography studies of three patients showed the blood supply to the tumor to be mainly from the internal maxillary branch of the external carotid artery. In all patients, the diagnosis was based on MR images and a surgical excision was planned. Conclusion: The diagnosis can be established based on the characteristic imaging findings and the clinical history without performing a biopsy.

Intramedullary pilocytic astrocytoma.

A 5-year-old female patient was admitted to Pediatric Neurosurgery Division, Gazi University Faculty of Medicine with complaints of abdominal pain, leg pain, and progressive weakness in legs for 2 months. Her medical history was unremarkable. The neurologic examination revealed decreased muscle strength of lower extremities (Grade 2 of 5). Brain magnetic resonance imaging (MRI) and spine MRI were performed. The cranial MRI revealed no pathologic changes. The thoracic spine magnetic resonance images with contrast administration showed a 2 2 10-cm cystic mass with peripheral enhancement located at the level of T3–T8 vertebrae (Fig. 1). The lesion caused an expansion of the cord. The spinal cord showed hyperintensity at T2-weighted images, which was consistent with vasogenic edema (Fig. 2). After antiedema treatment with steroids, T3–T7 laminectomy and subtotal resection of the lesion under intraoperative neuromonitoring was

Non-infantile variant of desmoplastic ganglioglioma: Conventional and advanced MR imaging characteristics

Desmoplastic infantile ganglioglioma is a paediatric brain tumor that is commonly seen in the infantile age group. Literature on the non-infantile variant of this low-grade supratentorial neoplasm is very scarce, except for a few case reports. Herein, we report a case of desmoplastic non-infantile ganglioglioma occurring at the age of 6 years and describe its conventional and advanced magnetic resonance imaging characteristics.

Imaging findings of an extradigital fibro-osseous pseudotumor.

Fibro-osseous pseudotumor (FOPT) is a rare and benign ossifying lesion. Described as the superficial variant of myositis ossificans (MO), this rare entity mostly occurs in the subcutaneous tissues of the digits. The FOPT clinicopathological features may mimic a variety of benign and malignant soft tissue lesions, and the diagnosis can be difficult when it arises in an unusual anatomic location. In this report we describe the clinical and radiological features of a case of an FOPT that involved the hypothenar region of the hand.
