Focal Xanthogranulomatous Pyelonephritis Associated with Xanthogranulomatous Cholecystitis: A Case Report.

Xanthogranulomatous inflammation is a rare inflammatory reaction, characterized by lipid-laden macrophages, known as xanthomas, in histopathologic examination. Aggressive xanthogranulomatous inflammation often manifests as local infiltration but does not affect distant organs unless combined with rare systemic diseases. We report a case of focal xanthogranulomatous pyelonephritis (XGP) associated with severe xanthogranulomatous cholecystitis.

Persistent primitive olfactory artery: CT angiographic diagnosis and literature review for classification and clinical significance.

Objectives: The aim of this study was to investigate the incidence of a persistent primitive olfactory artery (POA) and to review the literatures focusing on the classification and clinical significance of this variant.

Design: To identify cases with persistent POA, we reviewed the records of computed tomography (CT) angiography performed on 3,067 patients in our institution from January 1, 2011 to August 31, 2013. Literatures on the incidence and classification of a persistent POA were reviewed.

Primary intracranial ectopic craniopharyngioma in a patient with probable Gardner's syndrome.

The authors describe a patient with an adamantinomatous craniopharyngioma (CPG) arising in the cerebellopontine angle (CPA), who also had probable Gardner's syndrome. This 31-year-old man presented with headache and dizziness. Brain CT and MRI showed a 5 × 4-cm lesion with multiple small calcifications in the left CPA.

Diagnosis of persistent primitive olfactory artery using computed tomography angiography.

Persistent primitive olfactory artery (PPOA) is a rare anomaly of the anterior cerebral artery. We present one case of PPOA incidentally diagnosed with the aid of computed tomography (CT) angiography. A 24-year-old woman was admitted to our hospital after sudden onset of vertigo.

Two cases with persistent falcine sinus as congenital variation.

The falcine sinus is an abnormal anatomic structure located in the falx cerebri that is closed after birth and is rarely observed. We describe two cases of persistent falcine sinus. A 60-year-old woman presented with headache.

The incidence and clinical implications of congenital defects of atlantal arch.

Objective: Atlantal arch defects are rare. Few cadaveric and imaging studies have been reported on the variations of such anomalies. Our goal in this study was to examine the incidence and review the clinical implications of this anomaly.

Persistent trigeminal artery variant detected by conventional angiography and magnetic resonance angiography-incidence and clinical significance-.

Objective: Persistent trigeminal artery variant (PTAV) is an anastomosis between the internal carotid artery (ICA) and the cerebellar artery without any interposing basilar artery segment. We discuss its probable embryological origin and emphasize clinical implications.

Methods: Retrospectively 1250 conventional cerebral angiograms and 2947 cranial magnetic resonance angiographies (MRAs) were evaluated for the patients with PTAV.

Leiomyosarcoma of the ovarian vein: a case report with radiological findings.

Leiomyosarcomas of the ovarian vein are very rare. Four cases have been reported in the English language clinical literature. We present a case of leiomyosarcomas where the use of multi-detector CT had a substantial role in the establishment of the preoperative diagnosis.

Magnetic resonance imaging findings of surgically proven medial meniscus root tear: tear configuration and associated knee abnormalities.

Objective: To evaluate magnetic resonance imaging (MRI) findings of medial meniscal root tear and the correlation of medial meniscal root tear with other associated knee abnormalities.

Methods: We retrospectively assessed preoperative magnetic resonance images of 39 patients with arthroscopically confirmed medial meniscal root tear. Magnetic resonance imaging findings were retrospectively reviewed by 2 experienced musculoskeletal radiologists for consensus.

Retrievable biliary stent-graft management of refractory postoperative bile leakage.

The authors report a case of a successful outcome after retrievable biliary stent-graft management in a patient with refractory postoperative bile leakage. A 52-year-old man who underwent a Whipple operation presented with postoperative bile leakage. A percutaneous transhepatic biliary drainage (PTBD) catheter remained from the operation, and bile leakage persisted after 7 days of drainage with the catheter.

Fitz-Hugh-Curtis syndrome: CT findings of three cases.

Clinical manifestations and computed tomography (CT) findings of Fitz-Hugh-Curtis syndrome (FHCS) are relatively well stabilized as right upper quadrant abdominal pain and hepatic capsular enhancement because of perihepatitis associated with pelvic inflammatory disease caused by N. gonorrhoeae and C. trachomatis.

Inferior phrenic artery: anatomy, variations, pathologic conditions, and interventional management.

The inferior phrenic artery (IPA) is the most common source of extra-hepatic collateral blood supply for hepatocellular carcinoma (HCC) and frequently supplies HCCs located in the bare area of the liver. Other pathologic conditions including hemoptysis, diaphragmatic or hepatic bleeding due to trauma or surgery, and bleeding caused by gastroesophageal problems (eg, Mallory-Weiss tear or gastroesophageal cancer) may be related to the IPA. Over a 4-year period, the authors performed 383 interventional procedures related to the IPA.

Primary intraosseous malignant fibrous histiocytoma of the skull: a case report.

Malignant fibrous histiocytoma (MFH) is a rare primary neoplasm that constitutes less than 1% of the malignant tumors of bone, and involvement of the skull is very rare. We present a case of malignant fibrous histiocytoma of the skull, presenting an intraosseous lesion in a 43-yr-old woman. She had a rapidly growing, tender mass in the right parietal region.

Pulsatile tinnitus alleviated by contralateral neck compression: a case report.

A case of a 58-year-old man with right pulsatile tinnitus originating from a small dural arteriovenous fistula (DAVF) of the jugular bulb is described. The tinnitus was alleviated by contralateral neck compression. This unusual observation ruled out venous pulsatile tinnitus, although a temporal bone CT scan showed a high jugular bulb.
