AbstractWe report a case of a 31-month-old girl with visual impairment. Magnetic resonance imaging showed a large cystic lesion with a mural nodule in the suprasellar region. Biopsy was performed, and histopathological examination demonstrated an atypical extraventricular neurocytoma (EVN). EVN is a rare neuroepithelial tumor with similar histological and biological characteristics in comparison to intraventricular neurocytoma. However, the morphological appearance of EVN can show wide variability with significant overlap of imaging findings compared with other neoplasms. The majority of EVNs are seen supratentorial involving the cerebral hemispheres. An EVN in the sellar or suprasellar region has only been reported twice in adults and to our knowledge never in children.

Intramedullary Lesion

Symptomatic intramedullary arachnoid cysts are rare, especially in children; these lesions are rarely described as a cause of spinal cord compression in this age group. The authors report on an 18-month-old boy who experienced a sudden loss of his ability to stand and walk due to a paraparesis. Magnetic resonance imaging of the spine exhibited a cystic intramedullary lesion at the level of T5–6. A hemilaminectomy was performed, and after myelotomy the cystic lesion was decompressed by fenestration to the subarachnoid space. The histopathological examination verified the diagnosis of an arachnoid cyst. In the postoperative course the boy experienced complete resolution of the initial paraparesis.

Abstract We report the case of a patient with successful total removal of a previously undescribed intracranial tumor arising in the right lateral ventricle (probably of metaplastic origin). The histopathological examination revealed benign chondromatosis of the choroid plexus. The pathogenesis of this lesion, with special reference to synovial chondromatosis and to the differential diagnosis of solid neoplastic chondromas, their clinical features, and computed tomographic and magnetic resonance imaging findings, is presented and discussed.

Granulosa Cell Tumour (GCT) is a rare malignant ovarian tumour. Adult GCT variety is more common than juvenile variety and occurs usually in postmenopausal women. It showed a spectrum of the imaging findings due to various histological appearances. It may present with solid masses, multilocular cystic lesion or completely cystic lesion. Here, authors present an interesting case of a 27-year-old young female, who presented with a large lump in the abdomen. On Magnetic Resonance Imaging (MRI) there was a large well-defined, multilocular cystic lesion at superior aspect of the lesion and complex cystic, solid mass at inferior aspect. Functional MRI like diffusion weighted imaging which provides good image contrast helped in determining the malignancy despite a benign diagnosis on ultrasound guided biopsy and furthering the patient for histopathological examination to come to a final diagnosis.

✓ Echinococcosis affecting the spine is rare. The authors present the case of a 23-year-old man in whom features of thoracic spinal cord compression were demonstrated. Magnetic resonance imaging of the thoracic spine revealed an extradural cystic lesion involving the spine and paraspinal musculature. At surgery echinococcosis was confirmed, and subsequent histopathological examination also revealed Trichinella infestation of the paraspinal musculature. After undergoing decompressive surgery and albendazole therapy, the patient made a remarkable improvement. Although primary echinococcosis can affect the spine, concomitant infestation with Trichinella has not been reported. Surgery has to be followed by albendazole therapy.

Actinomycosis is an infrequent infectious disease caused by Actinomyces species. Actinomycoses in the nasopharynx are extremely rare, especially in the Rosenmüller’s fossa. This report presents a case of actinomycosis in the Rosenmüller’s fossa. A 75-year-old woman presented with a 6-month history of bloody sputum. A grayish-white caseous tissue was found in the right Rosenmüller’s fossa after retracting the torus tubarius. Magnetic resonance imaging showed a well-defined lesion with low-signal intensity on T1- and T2-weighted images; small low-signal areas were interspersed inside. The lesion was removed under an endoscope. Histopathological examination revealed eosinophilic, club-shaped structures surrounding a hematoxylophilic center, leading to the diagnosis of actinomycosis. The symptoms improved after 3 months of amoxicillin administration but recurred quickly. After 6 months of amoxicillin administration, the bloody sputum disappeared, and local and imaging findings were normal.

Preoperative diagnosis of neurenteric cysts can be difficult because the imaging findings of a neurenteric cyst may be similar to those of an arachnoid cyst. The authors report a case of a neurenteric cyst with xanthomatous changes in the prepontine area. This 4-year-old girl was admitted to their institution with intermittent neck pain and vomiting. Computed tomography showed a hypodense mass in the prepontine area. Magnetic resonance imaging showed a cystic lesion measuring ~ 4 × 3 cm. The brainstem was displaced posteriorly, and the cisterns in both cerebellopontine angles were widened. The signal intensity of the cyst was similar to that of cerebrospinal fluid. Adjacent to the basilar artery there was a solid component of the mass that enhanced after administration of Gd. Intraoperatively, the authors found a cystic mass containing clear fluid with a yellowish solid nodule. On the basis of histopathological findings, the lesion was diagnosed as a neurenteric cyst with xanthomatous changes.

A 10 year old girl was admitted to our hospital due to headache, nausea, and weight loss for about half a year. She also had visual field disorders. Suprasellar tumor was found by X-ray computed tomography, and magnetic resonance imaging showed a ring-like lobulated enhanced mass with hemorrhage and necrosis. Biopsy of this lesion showed primary intracranial choriocarcinoma on histopathological examination. The serum human chorionic gonadotropin (hCG) level was measured after the biopsy and was elevated at 71,298.2 IU/L. The patient died due to hydrocephalus caused by an increase in the size of the tumor with a larger amount of hemorrhage than the preoperative features. If young patients present with a suprasellar lobulated mass with hemorrhage, the serum hCG level should be measured before operation.

Dauguma šių navikų yra besimptomiai ir nustatomi atsitiktinio ištyrimo metu. Dažniausia jų lokalizacija yra užpakalinis tarpuplautis ir retroperitonis tarpas. Klinikinis atvejisProfilaktinio tyrimo metu atlikus pilvo organų echoskopinį tyrimą 23-ejų metų pacientei diagnozuotas dešiniosios pilvo pusės navikas. Atlikus magnetinio rezonanso tomografijos tyrimą ir įvertinus histologinę biopsinės medžiagos išvadą nustatyta retroperitoninio tarpo ganglioneuromos diagnozė. Ligonei planine tvarka buvo atlikta naviko ekstirpacija. Bendras hospitalizacijos laikas – 13 dienų. IšvadaRetroperitoninio tarpo ganglioneuromų diagnostika palyginti sudėtinga dėl menko naviko simptomiškumo ir tyrimo metodų specifiškumo. Operacija išlieka šių navikų gydymo aukso standartu.

Most ganglioneuromas are asymptomatic and diagnosed incidentally. The most common site of occurence is posterior mediastinum and retroperitoneum. Case reportA 23-year-old female patient was incidentally found to have a right-side abdominal tumour on ultrasonography. Magnetic resonance imaging and the histopathological examination revealed the diagnosis of retroperitoneal ganglioneuroma. The patient underwent the tumour extirpation. The total hospitalization lasted 13 days. ConclusionUnfortunately, the diagnostics of retroperitoneal ganglioneuromas is still relatively difficult because of the lack of specific symptoms and imaging findings. Surgical treatment still remains a “gold standard” in the management of these tumours. Keywords: ganglioneuroma, retroperitoneum, tumour extirpation

AbstractHydranencephaly is a fetal central nervous system disorder in which most of the cerebral hemispheres are damaged and largely replaced with cerebrospinal fluid. We present susceptibility-weighted imaging findings in an infant with hydranencephaly, who showed foci of signal loss mainly at the peripheral portion of the thalamus and falx cerebri. Although the exact cause of hydranencephaly has not been established, these findings suggest previous hemorrhage and parenchymal destructive changes.
