Subsynovial epidermal inclusion cyst of the knee.

We report a case of a subsynovial epidermal inclusion cyst in a 47-year-old woman with a painful spontaneous swelling of the right knee and a 2-year history of puncture and arthroscopy. Epidermal inclusion cysts are one of the most common benign subcutaneous tumours. Very rarely, they are located in an articulation and can cause an inflammatory reaction when rupture occurs.

Supra-inguinal injection for fascia iliaca compartment block results in more consistent spread towards the lumbar plexus than an infra-inguinal injection: a volunteer study.

Background And Objectives: Lumbar plexus block has been used to provide postoperative analgesia after lower limb surgery. The fascia iliaca compartment block (FICB) has been proposed as an anterior approach of the lumbar plexus targeting the femoral, obturator and lateral femoral cutaneous nerve. However, both radiological and clinical evidence demonstrated that an infra-inguinal approach to the fascia iliaca compartment does not reliably block the three target nerves.

Duplicated Collecting System with Ectopic Vaginal Implantation.

We present a case of a 54-year-old woman with a left-sided complete duplication of the ureter. The upper moiety drains in the proximal third of the vagina, which results in an ureterocele and urinary incontinence. The ureteral orifice of lower moiety ureter was normal.

Intracranial Solitary Fibrous Tumor.

Solitary fibrous tumours are rare mesenchymal spindle-cell tumours that occur most often in the visceral pleura or liver. If they occur intracranially, they are extra-axially located and develop from the meninges. In those cases, the differential diagnosis has to be made with other intracranial extra-axial-located tumours, such as meningeoma and hemangiopericytoma.

MR imaging of the anatomy of the anterior horn of the medial meniscus.

Background In cadaveric and arthroscopic studies different insertion locations of the anterior horn of the medial meniscus (AHMM) have been described. Purpose To investigate if the different insertion locations of the AHMM, as described in cadaveric studies, can be determined on magnetic resonance imaging (MRI). Material and Methods MR images of 100 patients without meniscal tears on MRI were retrospectively evaluated.

Atretic Cephalocele.

A 1-year-old girl was referred to the neurosurgery department. The patient presented with a swelling on the vertex of the head which was present at birth but increased gradually over time. There were no perinatal problems and the child developed normally.

Repair of distal biceps tendon ruptures using a suture anchor and an anterior approach.

In a prospective study, eight consecutive patients with nine ruptures of the distal biceps tendon underwent repair through a single incision. All patients were satisfied with their clinical results and had full ranges of elbow and forearm motion. There were no radial nerve injuries and no radio-ulnar synostoses.

Neurovascular compression by a subpectoral lipoma. A case report of a rare cause of thoracic outlet syndrome.

Background: Lipomas are benign soft tissue tumours, progressively expanding in volume. Beside frequent aesthetic consequences, lipomas can also exert pressure on surrounding tissues and structures.

Materials And Methods: A case of a subpectoral infraclavicular lipoma compressing the axillo-subclavicular neurovascular bundle, produced unilateral brachialgia, thereby simulating a Thoracic Outlet Syndrome.

Hepatic bile duct hamartomas (von Meyenburg Complexes): MR and MR cholangiography findings.

Multiple bile duct hamartomas (MBDHs) of the liver, also known as von Meyenburg complexes, are easily confused with diffuse metastatic disease of the liver on US and CT. At present, histologic examination after tissue preevaluation is usually necessary for definite diagnosis. We report four cases in which the MR features, and especially the MR cholangiographic (MRC) findings, were highly suggestive for MBDH.

Hemangiopericytoma of the parotid gland: CT and MR features.

Hemangiopericytomas are uncommon vascular neoplasms with rare occurrence in the head and neck region. They originate from the pericytes, which are small, oval cells encircling capillaries. Hemangiopericytomas traditionally appear in the retroperitoneum and in the capillaries of the extremities.

Non-invasive diagnostic assessment of extensive vertebral artery tortuosity with enlargement of the intervertebral foramen.

Two cases with an incidental finding of a widened intervertebral foramen due to extensive tortuosity of the vertebral artery are presented. Computed tomography angiography and magnetic resonance imaging/magnetic resonance angiography (MRA) both proved to be useful as non-invasive techniques to provide the diagnosis. In-plane saturation is a disadvantage seen with the two-dimensional time-of-flight MRA technique.

Hypertrophy and pseudohypertrophy of the lower leg following chronic radiculopathy and neuropathy: imaging findings in two patients.

Enlargement of the ipsilateral muscle compartment is an exceptional finding in patients with chronic radiculopathy, peripheral nerve injury, anterior horn cell diseases, or acquired peripheral neuropathy. We report radiographic, ultrasonographic, CT and MRI findings in a patient with chronic S1 radiculopathy and another with chronic neuropathy of the common fibular nerve (L4-S2), both presenting with painless enlargement of the calf muscles.

Intralobar pulmonary sequestration supplied by the right coronary artery.

Bronchopulmonary sequestrations are malformations that are often congenital; they consist of isolated nonfunctioning lung segments having no communication with functional tracheobronchial elements of the surrounding lung. They are supplied by single or multiple branches from the distal thoracic or proximal abdominal aorta, or from the celiac, splenic, intercostal, subclavian, or pulmonary artery. Due to the absence of ventilation, the lung tissue can become chronically infected.

Occipital pain in osteoid osteoma of the atlas. A report of two cases.

Study Design: Two cases of occipital pain caused by an osteoid osteoma of the atlas are presented.

Objectives: To describe the management of occipital pain in two young patients.

Summary Of Background Data: Osteoid osteoma is a benign lesion mostly affecting the long bones.

Pelvic congestion syndrome: demonstration and diagnosis by helical CT.

Pelvic pain is a common gynaecological complaint, sometimes without any obvious etiology. We report a case of pelvic congestion syndrome, an often overlooked cause of pelvic pain, diagnosed by helical computed tomography. This seems to be an effective and noninvasive imaging modality.

Mycotic pseudo-aneurysm of the extracranial carotid artery.

A rare case of mycotic pseudo-aneurysm of the common carotid artery as a complication in an immunosuppressed paediatric patient is presented. Treatment of pseudo-aneurysms of the common carotid artery is generally considered to be an emergency, necessitating quick and accurate diagnosis. In patients with septicemia, angiography has to be avoided.
