Two cases of fibrolipomatous hamartomas of the median nerve: A rare entity with pathognomonic MRI features.

Fibrolipomatous hamartomas of the median nerve are rare, benign tumors characterized by the overgrowth of fibro-fatty tissue within the nerve sheath, often leading to nerve compression. This report presents 2 cases: a 33-year-old man with a gradually enlarging wrist mass and a 48-year-old woman, initially diagnosed with De Quervain's tenosynovitis for radial pain, who was found to have an incidental fibrolipomatous hamartoma on MRI. In both cases, MRI played a pivotal role in diagnosis, revealing characteristic features that enabled a definitive, noninvasive diagnosis.

Research paper: Two cases of multiple osteoid osteomas in young patients treated with cryoablation: Diagnosis, technical efficacy, and follow-up.

Osteoid osteomas are benign bone tumors characterized by severe localized pain, often challenging the daily lives of young patients. While these tumors are typically solitary, rare cases of multiple osteoid osteomas have been reported. This research paper presents a case series of 2 young patients with multiple osteoid osteomas, highlighting their clinical presentation, diagnostic workup, treatment with cryoablation, and follow-up.

Therapeutic ultrasound related pain threshold in elite track & field athletes with tibial bone stress injuries.

Objective: Tibial stress injuries are challenging in terms of early diagnosis, management strategy, and safe return-to-play. In the present study, pain production associated with the application of therapeutic ultrasound (TUS) was used as a primary diagnostic tool to assess tibial bone stress injuries, and the sensitivity of this procedure was compared with Magnetic Resonance Imaging (MRI).

Subject And Methods: The study was designed as a retrospective analysis of prospectively collected data on tibial bone stress injuries in elite Track and field athletes attending the National Track and Field Athletics Centre in Thessaloniki, Greece, in the period 1995-2007.

More than meets the eye: A case of synchronous ipsilateral clear cell renal cell carcinoma and urothelial carcinoma of the pelvicalyceal system and literature review.

Background And Aim: The synchronous occurrence of renal cell carcinoma and urothelial carcinoma of the renal pelvis in the same kidney is extremely rare, although previously reported. With this study we aim to present our case and provide a literature review on this entity.

Methods: An otherwise healthy 43-year-old military male with the chief complaint of left plank pain was seen in the office.

Does Bone Regrow After Notchplasty in ACL Reconstruction? A Prospective Computed Tomography Study With 2-Year Follow-up.

Background: During notchplasty in anterior cruciate ligament (ACL) reconstruction, bone is excised from the lateral and roof area of the notch to widen the intercondylar space and avoid notch-graft impingement in extension. There are concerns that bone regrowth of the area will cause narrowing and increase the risk of complications.

Purpose: To determine the possibility of late narrowing of the notch after notchplasty using computed tomography (CT) analysis.

Synchronous bilateral testicular cancer with discordant histopathology occurring in a 20-year-old patient: A case report and review of the literature.

Introduction: Bilateral testicular tumors are very rare, accounting for 1%-5% of all testicular germ-cell tumors (TGCTs). The vast majority of primary bilateral TGCTs are metachronous, with synchronous tumors comprising approximately 0.5%-1% of all cases.

Giant Sclerosing Epithelioid Fibrosarcoma of the Thigh: A Case Report.

Case: We present a case of a 35-year-old-man with a giant sclerosing epithelioid fibrosarcoma (SEF) of the thigh. The patient presented with a history of a painful thigh mass. Plain radiographs revealed a soft-tissue mass with extensive calcifications, whereas on magnetic resonance imaging, a lobulated mass between the adductors and the posterior muscles of the thigh was noted.

A computed tomography cadaveric study of the radiological anatomy of the patella: the size of the patella correlates with bone bridge between tunnels and R angles are introduced for safe tunnel drilling during MPFL reconstruction.

Purpose: To measure the safe range of angles during tunnel drilling and map ideal patella tunnel placement with the use of preoperative computed tomography (CT) scan and compare results after medial patellofemoral ligament (MPFL) reconstruction using a hardware-free patellar fixation technique with two semi-patellar tunnels between a) a free-hand technique, and b) its modification with the use of an anterior cruciate ligament (ACL) tibia aiming device.

Methods: CT scan was performed on 30 fresh-frozen cadaveric knees a) prior to any intervention and b) after MPFL reconstruction. For MPFL reconstruction, specimens were randomly allocated to 1) Group A, which consisted of knees operated with free-hand, hardware-free patellar fixation technique with two semi-patellar tunnels and 2) Group B, which consisted of knees operated on with a technique modification with the ACL tibia device.

Psoriatic onycho-pachydermo periostitis (POPP): a case report treated successfully with IL-17 blockade and a literature review on characteristics, pathogenesis, and treatment.

Psoriatic onycho-pachydermo periostitis (POPP) is characterized by psoriatic onychodystrophy, connective tissue thickening, and periostitis of the distal phalanges (DPs), producing a drumstick-like deformity. Our aim was to present the first case of POPP treated successfully with an IL-17 inhibitor, perform a literature review of its characteristics and treatment, and explore the possible pathogenesis. We conducted a systematic review of previously presented POPP cases.

Be cautious of "complex hydrocele" on ultrasound in young men.

Hydrocele is the most common benign cause of painless scrotal enlargement and only very rarely can be reactive to an underlying testicular tumor. We present the case of a healthy young man, complaining of mild left scrotal discomfort and swelling. Physical examination revealed a non-tender fluctuant left scrotum and serum tumor markers were normal.

Spectrum of skeletal disorders during the peripartum period: MRI patterns.

Pregnancy is a normal condition in which a combination of biomechanical and hormonal changes may result in a wide spectrum of skeletal disorders. Skeletal overloading due to postural and weight changes, combined with increased ligamentous laxity stemming from the action of relaxing and the risk of pregnancy-related osteoporosis during childbearing, childbirth, and postpartum, have been associated with various pathologies. Owing to the heterogeneity of proposed contributing factors, skeletal lesions in the peripartum period may be related to different pathogenesis depending on the metabolic status of the patient and the degree of biomechanical stress; thus, a fatigue or insufficiency discrimination is not always easy to make.

Incidental finding of Zinner syndrome in a Greek military recruit: a case report of a rare clinical entity.

Background: Zinner syndrome represents a rare congenital malformation of the urinary tract. It comprises a constellation of Wolffian duct anomalies and is almost exclusively encountered as a classic triad of seminal vesicle cysts, ejaculatory duct obstruction and renal agenesis. Patients can be either asymptomatic or symptomatic.

A Rare Variation of Transverse Testicular Ectopia (TTE) in a Young Adult as an Incidental Finding during Investigation for Testicular Pain.

Transverse testicular ectopia (TTE) with fused vas deferens is an extremely rare clinical entity. Herein, we present a case of a 19-year-old patient with persistent left testicular pain lasting for a week. Clinical examination revealed an empty right hemiscrotum, a normal left-sided descended testis, and in close proximity a mass-like structure resembling testicular parenchyma.

Giant nonfunctioning adrenal tumors: two case reports and review of the literature.

Background: There are an estimated 1-2 cases per million per year of adrenocortical carcinoma in the USA. It represents a rare and aggressive malignancy; it is the second most aggressive endocrine malignant disease after anaplastic thyroid carcinoma. Non-secretory adrenal masses are diagnosed late due to a mass effect or metastatic disease or found incidentally (adrenal incidentalomas).

Tensor Fasciae Suralis Muscle: Report of a Symptomatic Case With Emphasis on Imaging Findings.

We report a case of a symptomatic tensor fasciae suralis (TFS) muscle in an elite jumper, with a very rare tear in its origin. The TFS muscle must be recognized and differentiated from other pathologic entities in the popliteal region. The magnetic resonance imaging (MRI) and ultrasound (US) can reliably identify this variant and its pathology.

Morel-Lavallée Lesions of the Knee: MRI Findings Compared With Cadaveric Study Findings.

Objective: The purpose of this study is to describe the MRI findings and treatment decisions and outcome for Morel-Lavallée lesions (MLLs) of the knee and to investigate whether evidence exists to support an increased frequency of such lesions on the medial or lateral side by performing a cadaveric experiment.

Materials And Methods: In a 4-year period, 24 MRI studies of 24 consecutive patients (16 male patients and eight female patients) with knee MLLs were retrospectively reviewed. Patient demographic characteristics, treatment decisions and outcome, and associated injuries were recorded.

Soft tissue pseudotumours: a pictorial review with emphasis on MRI.

Background: Several tumour-like conditions of the soft tissues may be encountered in clinical practice, or when patients undergo radiologic examinations. Al-though advances in cross sectional imaging (ultra-sound, MDCT and MRI) play a pivotal role in the correct evaluation of tumour-like lesions, a systematic approach is needed to achieve a definitive diagnosis or limit the differential diagnosis. Clinical history, physical examination and anatomic location are of paramount importance.

Para-articular extraskeletal chondroma mimicking first metatarsophalangeal synovitis.

Extraskeletal chondroma is a rare benign tumor with symptoms that could mimic other common musculoskeletal pathological entities. We present a rare case of an extraskeletal para-articular chondroma of the first metatarsophalangeal joint which was initially misinterpreted as joint synovitis, based on magnetic resonance imaging findings. Histology revealed benign chondroma of the foot, which was finally treated with radical surgical excision.
