SummaryObjective: To report femoral neuropathy caused by nerve entrapment associated with diffuse idiopathic skeletal hyperostosis (DISH).Study Design: Case report.Animal: Seven-year-old female spayed Boxer dog.Results: Entrapment of the right femoral nerve due to DISH caused a femoral nerve deficit and atrophy of muscle groups associated with the affected nerve. A combination of computed tomography and magnetic resonance imaging was performed to provide a diagnosis. Amputation of the right transverse process of the sixth lumbar vertebra at the level of nerve entrapment relieved the neurological abnormality.Conclusions: Nerve entrapment leading to neurapraxia may occur concurrently with DISH and surgery in this case was successful in restoring function.Clinical relevance: Peripheral neuropathy from nerve entrapment should be considered in patients with DISH. Surgical amputation of impinging osseous structures may be indicated for relief of femoral neuropathy.

Case Presentation: A 14-year-old boy presented to the emergency department complaining of severe groin pain on the right side following a minor fall. Computed tomography and magnetic resonance imaging revealed a hematoma in his right iliacus muscle. He was diagnosed with a traumatic iliacus hematoma, and he recovered spontaneously with short-term oral analgesics. Discussion: Traumatic iliacus hematomas are rare entities and subside with conservative management in most cases. However, this condition may be associated with femoral nerve palsy, and surgery is indicated in severe cases. Traumatic iliacus hematoma should be considered in the differential diagnosis of severe groin pain.

Iliopsoas hematoma is a serious complication that can occur in bleeding disorders, most commonly hemophillia but it can also be seen in von Willebrand disease (vWD) in less frequency. This can cause muscle pain, muscle dysfunction and sometimes even femoral nerve palsy. Iliopsoas hematomas can be diagnosed by the usage of ultrasonography, computed tomography (CT) or magnetic resonance imaging (MRI). Here we report a case of a 20-year-old boy who presented to us with complaints of pain in the right lower quadrant, flank, and inguinal region for a week. He was diagnosed with vWD type 3 when he was 10 years old. The symptoms started after he had tried to kick start his motorbike vigorously. Clinical examination revealed the patient to be in an anti-pain posture and to have tenderness at sites where he complained of pain. A subsequent CT scan showed that there was an iliopsoas hematoma of size 10×6 cm. The patient was managed conservatively with factor replacement and physiotherapy following which there was amelioration in the symptoms and the patient recovered well.

Abstract We report a case of 56-year-old patient suffering from myxopapillary ependymoma of filum terminale at the level of the fifth lumbar vertebra. The patient presented with progressive complaints of permanent pain in the anal and sacral region with duration of 8 months. When sneezing or attempting to do brisk movements, the pain irradiated to the posterior surface of the right thigh. Vertebral syndrome was absent. Neurological examination demonstrated no other abnormalities. Magnetic-resonance imaging showed intradural tumor of cauda equina at the level of the fifth lumbar vertebra. The present article discusses the role of MRI in the diagnosis of clinical cases presenting with atypical lumboradiculalgia. We have put an emphasis on the early diagnosis of myxopapillary ependymoma of filum terminale which has an impact on the surgical strategy and postoperative outcome.

Objective: The authors report a case of femoral nerve schwannoma by MR imaging findings. Case: A patient presenting with right inguinofemoral pain and swelling was submitted to a Gadolinium-enhanced Magnetic Resonance Imaging (MRI): a schwannoma arising from the femoral nerve in the right inguinofemoral area was disclosed. She  underwent microsurgical procedure, with total removal of the lesion. Postoperatively, the inguinofemoral pain and swelling disappeared, with complete relief of symptoms. Conclusion: The authors stress that femoral nerve schwannoma in the inguinofemoral place should be considered according to MRI findings.

Background: Bertolotti’s syndrome (i.e., varying extent of fusion between the last lumbar vertebra and the first sacral segment) or lumbosacral transitional vertebrae is a rare cause of back pain. Notably, this syndrome is one of the differential diagnoses for patients with refractory back pain/sciatica. Case Description: A 71-year-old male presented with low back pain of 3 years duration that radiated into the right lower extremity resulting in numbness in the L5 distribution. He then underwent a minimally invasive approach to resect the L5 “wide” transverse process following the CT diagnosis of Bertolotti’s syndrome. Prior to surgery, patient reported pain that was exacerbated by ambulation that resolved post-operative. Conclusion: Bertolotti’s syndrome is one of the rare causes of sciatica that often goes undiagnosed. Nevertheless, it should be ruled out for patients with back pain without disc herniations or other focal pathology diagnosed on lumbar MR scans.

Abstract Background The appropriate choice of postoperative analgesia for pyothorax surgery is unclear since local infection could contaminate the catheter used for regional blocks and bacteremia can lead to disordered coagulation. We performed erector spinae plane block (ESPB) in a pyothorax patient undergoing emergency re-open thoracotomy. Case presentation An 81-year-old male with internal jugular vein stenosis on aspirin therapy was scheduled for pyothorax drainage and residual middle lobectomy 14 days after he underwent open right lower lung lobectomy for lung cancer. ESPB was performed with injection of 20 ml of 0.375% levobupivacaine at the Th5 transverse process of the right side under ultrasound guidance. Although he needed intravenous pentazocine for pain on postoperative day 0, no more analgesics were required postoperatively. NRS score ranged from 0 to 1 thereafter. Conclusions ESPB provided effective postoperative analgesia following emergency re-open thoracotomy for our pyothorax patient. ESPB might be the appropriate choice for postoperative analgesia following pyothorax surgery.

AbstractLesions of the cerebellopontine angle (CPA) in young children are rare, with the most common being arachnoid cysts and epidermoid inclusion cysts. The authors report a case of an encephalocele containing heterotopic cerebellar tissue arising from the right middle cerebellar peduncle and filling the right internal acoustic canal in a 2-year-old female patient. Her initial presentation included a focal left 6th nerve palsy. Magnetic resonance imaging was suggestive of a high-grade tumor of the right CPA. The lesion was removed via a retrosigmoid approach, and histopathologic analysis revealed heterotopic atrophic cerebellar tissue. This report is the first description of a heterotopic cerebellar encephalocele within the CPA and temporal skull base of a pediatric patient.

Nasosinus metastases from kidney cancer are an unusual clinical presentation although some cases are reported in the literature. Among these cases, sphenoidal metastases are even rarer. Here we report a case of lone sphenoid metastasis in patients with papillary renal cell cancer. Eight months after radical nephrectomy, the patient presented with progressively worsening diplopia. Magnetic resonance imaging showed a mass in the right sphenoid sinus. Histopathological examination of the biopsy sample confirmed diagnosis of sinonasal metastasis from papillary renal cell carcinoma. The patient was declined for surgical management and received stereotactic body radiation therapy. Reassessment MRI at 4 months showed a complete response of the treated sphenoid lesion.

AbstractThe characteristics of aortic valvular outflow jet affect aortopathy in the bicuspid aortic valve (BAV). This study aimed to elucidate the effects of BAV morphology on the aortic valvular outflow jets. Morphotype-specific valve-devising apparatuses were developed to create aortic valve models. A magnetic resonance imaging-compatible pulsatile flow circulation system was developed to quantify the outflow jet. The eccentricity and circulation values of the peak systolic jet were compared among tricuspid aortic valve (TAV), three asymmetric BAVs, and two symmetric BAVs. The results showed mean aortic flow and leakage did not differ among the five BAVs (six samples, each). Asymmetric BAVs demonstrated the eccentric outflow jets directed to the aortic wall facing the smaller leaflets. In the asymmetric BAV with the smaller leaflet facing the right-anterior, left-posterior, and left-anterior quadrants of the aorta, the outflow jets exclusively impinged on the outer curvature of the ascending aorta, proximal arch, and the supra-valvular aortic wall, respectively. Symmetric BAVs demonstrated mildly eccentric outflow jets that did not impinge on the aortic wall. The circulation values at peak systole increased in asymmetric BAVs. The bicuspid symmetry and the position of smaller leaflet were determinant factors of the characteristics of aortic valvular outflow jet.

Purpose: The aim of this study was to assess the volumetry of the hippocampus in the Leber’s hereditary optic neuropathy (LHON) of blind patients. Methods: A total of 25 patients with LHON were randomly included into the study from the national health database. A total of 15 patients were selected according to the inclusion criteria. The submillimeter segmentation of the hippocampus was based on three-dimensional spoiled gradient recalled acquisition in steady state (3D-SPGR) BRAVO 7T magnetic resonance imaging (MRI) protocol. Results: Statistical analysis revealed that compared to healthy controls (HC), LHON subjects had multiple significant differences only in the right hippocampus, including a significantly higher volume of hippocampal tail (p = 0.009), subiculum body (p = 0.018), CA1 body (p = 0.002), hippocampal fissure (p = 0.046), molecular layer hippocampus (HP) body (p = 0.014), CA3 body (p = 0.006), Granule Cell (GC) and Molecular Layer (ML) of the Dentate Gyrus (DG)–GC ML DG body (p = 0.003), CA4 body (p = 0.001), whole hippocampal body (p = 0.018), and the whole hippocampus volume (p = 0.023). Discussion: The ultra-high-field magnetic resonance imaging allowed hippocampus quality visualization and analysis, serving as a powerful in vivo diagnostic tool in the diagnostic process and LHON disease course assessment. The study confirmed previous reports regarding volumetry of hippocampus in blind individuals.
