One of the Rare Causes of Acute Abdomen Leading to Subileus: Jejunal Diverticulitis.

Background: Jejunal diverticulitis is one of the rare causes of acute abdomen generally seen in the elderly. Jejunal diverticulosis was defined as the herniation of the mucosa and the submucosa from the inside of the muscular layer of the bowel wall on the mesenteric side of the intestine.

Case Report: We presented the intraoperative and pathological findings of a 69-year-old male patient who had presented with complaints about abdominal pain, nausea, and vomiting and been operated upon due to subileus and peritonitis induced by large-sized jejunal diverticulitis, along with his computed tomography (CT) findings.

Temporal Lobe Parenchyma Herniation into the Transverse Sinus: MRI Findings in a Case.

Brain parenchyma herniation into dural venous sinus which is a uncommon entity, can cause dural venous sinus filling and simulate sinus thrombosis and other pathologies. It is isointense to brain parenchyma on all sequences by magnetic resonance imaging, surrounded by a cerebrospinal fluid rim and is seen to be contiguous with brain tissue on images. We report a rare case with spontaneous occult herniation of temporal lobe tissue into the left transverse sinus that may associated with headache.

Objectives: Our purpose was to determine whether the combination of a qualitative elasticity scoring method and a semiquantitative strain index method by sonoelastography is useful for differentiating between benign and malignant breast masses.

Methods: Seventy-eight lesions in 71 consecutive patients with solid breast masses (62 benign and 16 malignant) were prospectively included in this study. For each lesion, B-mode sonographic and sonoelastographic images were obtained.

The metaplastic variant of Warthin tumor of the parotid gland: dynamic multislice computerized tomography and magnetic resonance imaging findings with histopathologic correlation in a case.

Metaplastic Warthin tumor is a rarely seen subtype of Warthin tumor. It can resemble squamous carcinomas histopathologically, because it contains atypical squamous cells on the necrotic surface. Making a diagnosis can become easier by knowing this entity of Warthin tumor well and by correlating the radiologic findings with pathology.

Extended field-of-view sonography: evaluation of the superficial lesions.

Objective: To evaluate the usefulness of extended-field-of-view 2-dimensional ultrasonography technique in superficial lesions.

Methods: During a 6-month period, 44 patients with superficial lesions on various parts of their bodies were evaluated with extended-field-of-view ultrasonography in addition to routine traditional 2-dimensional ultrasonography. If the diagnosis could not be made without the extended-field-of-view images, it was considered diagnostic.

Benign paroxysmal positional vertigo after radiologic scanning: a case series.

Introduction: Benign paroxysmal positional vertigo (BPPV) is the most common type of vertigo. It is frequently seen in elderly patients, and the course of the attack may easily mimic cerebrovascular disease. A BPPV attack after a radiologic examination has not been reported previously.

[Non-Hodgkin's lymphoma of the parotid gland].

Most of the primary malignant lymphomas of the salivary glands originate from the parotid gland. We presented two patients who were admitted with a painless mass in the parotid region and diagnosed to have a lymphoma. Physical examination of a 66-year-old male patient showed a relatively mobile, painless, and firm mass at the inferior aspect of the right parotid gland.

[Multiple myeloma of the sphenoid sinus: a case report].

Plasma cell neoplasms of the head and neck region can be extramedullary plasmacytoma of the bone, solitary plasmacytoma of the bone, and local manifestations of multiple myeloma. A 70-year-old male patient was admitted to our hospital with diplopia of four-day history. Magnetic resonance imaging showed soft tissue in the sphenoid sinus.

[Brain MR perfusion and MR spectroscopy in differentiation of radiation necrosis from tumor recurrence (case report)].

It is not always possible to differentiate tumor recurrence from radiation necrosis using conventional MR images. In this report we present a case of pathologically proven radiation necrosis which appeared as nodular contrast enhancement on conventional MR images in a patient who was surgically treated for grade II astrocytoma 5 years ago. There were decreased choline, creatine and N-acetyl aspartate peaks and significantly increased lipid peak on multivoxel H1-MR spectroscopy while there was no significant perfusion increase on MR perfusion.

[Dynamic contrast-enhanced brain perfusion imaging: Technique, pitfalls and problems].

Conventional magnetic resonance and computed tomography imaging, despite their sensitivity in delineating tissue anatomy and detecting head and neck pathology, are nonspecific in their ability to physiologically characterize abnormal tissue. The perfusion imaging attempts to measure the steady-state delivery of blood to a given parenchymal region. In this article, the technique of magnetic resonance perfusion and computed tomographic perfusion is discussed in addition to the pitfalls and problems in the light of the latest literature and our own experience.

[Case report: Complex composite odontoma: Plain radiography and computed tomography findings].

Complex composite odontoma is a rare benign odontogenic hamartoma seen in association with a primary tooth. Although it is seen most frequently between 10-19 years of age, here we present a lesion of unusual size in the mandible of a 6-year-old boy and report its clinical, radiographic, CT and histologic findings. Also, we discuss the value of three dimensional images.

[Case report: Selective intraarterial thrombolysis of subacute superior mesenteric artery thromboembolism].

Acute embolic occlusion of the superior mesenteric artery is associated with a high mortality rate. Selective thrombolytic therapy appears to be effective in the treatment of mesenteric thromboembolism particularly in elderly patients with a high operative risk. We describe a case of subacute mesenteric artery occlusion in a 69-year-old man treated successfully by selective intraarterial infusion of urokinase two days after he became symptomatic.
