  • Ultrasound of acquired posterior fossa abnormalities in the newborn. [Review]
    Pediatr Res. 2020 Mar; 87(Suppl 1):25-36.Fumagalli M, Parodi A, … eurUS.brain group
  • Neonatal brain sonography is part of routine clinical practice in neonatal intensive care units, but ultrasound imaging of the posterior fossa has gained increasing attention since the burden of perinatal acquired posterior fossa abnormalities and their impact on motor and cognitive neurodevelopmental outcome have been recognized. Although magnetic resonance imaging (MRI) is often superior, poste…
  • Stage III Non-small Cell Lung Cancer: A UK National Survey of Practice. [Journal Article]
    Clin Oncol (R Coll Radiol). 2020 Mar 23 [Online ahead of print]Evison M, Edwards J, … Popat S
  • CONCLUSIONS: This survey has highlighted the need for infrastructure development, such as reflex PD-L1 testing and joint surgical and oncology clinics. Further research into the impact of multimodality treatment on quality of life and education to improve confidence in multimodality treatment could all drive improvements in stage III NSCLC management.
  • High FDG Uptake in Pleomorphic Hyalinizing Angiectatic Tumor. [Journal Article]
    Clin Nucl Med. 2020 Mar 23 [Online ahead of print]Yamamoto A, Kikuchi Y, … Kaminaga T
  • PHAT (pleomorphic hyalinizing angiectatic tumor) is a rare, locally aggressive, low-grade mesenchymal neoplasm of uncertain lineage with a predilection for the lower extremities. We report a 74-year-old woman with an enlarging mass on the right popliteal fossa undergoing FDG PET/CT to characterize its biological activity. Increased accumulation of FDG (SUVmax, 23.0) in the solid component of the …
  • Uni-hemispheric hyperperfusion in the early postictal state: case report. [Journal Article]
    BMC Neurol. 2020 Mar 24; 20(1):108.Gonzalez AV, Schülke C, Buerke B
  • CONCLUSIONS: To the authors' knowledge, this is the first report of an early postictal state describing sharply delimited uni-hemispheric hyperperfusion and hemispheric alteration of the cerebellum with an equally split rhombencephalon. Surprisingly, these changes were not associated with any focal neurological signs. To prevent misdiagnosis of perfusion alterations in seizures, radiologists and neurologists should be aware of the limitations of CT perfusion maps and software reconstructions. Novel use of CT perfusion reconstruction using peak enhancement helped in identifying the cerebral pathology.
  • Growing Skull Fracture of Temporal Bone in Adults: A Case Report and Literature Review. [Journal Article]
    Ear Nose Throat J. 2020 Mar 24 [Online ahead of print]Yan XH, Qiu K, … Zhao Y
  • Growing skull fracture (GSF) is an uncommon post-traumatic complication, which accounts for approximately 0.05% to 1% of all skull fractures. Delayed diagnosis of GSF in adulthood is rare and often involved with a variety of neurological symptoms. Here, we reported an adult patient, with an interval of 17 years from initial head trauma to first diagnosis of GSF. The patient complained of short pe…
  • Euclidean Relationship between the Superior Semicircular Canal and the Arcuate Eminence. [Journal Article]
    J Neurol Surg B Skull Base. 2020 Apr; 81(2):165-171.Nourbakhsh A, Tang Y, … Coelho DH
  • Objective  This study was aimed to better characterize the surgical anatomy of the floor of the middle cranial fossa using three dimensional Euclidean relationships between the arcuate eminence (AE), the superior semicircular canal (SSC), and the geniculate ganglion (GG). Study Design  Submillimeter distances were recorded from computed tomography (CT) scans of 50 patients (100 sides). The AE, ap…
  • Audiometric Outcomes and Middle Ear Disease following Cerebrospinal Fluid Leak Repair. [Journal Article]
    Otolaryngol Head Neck Surg. 2020 Mar 24 [Online ahead of print]Yancey KL, Manzoor NF, … Rivas A
  • CONCLUSIONS: Lateral skull base repair of CSF leaks maintained or improved hearing. Patients with preexisting chronic ear disease were more likely to require additional intervention to sustain adequate middle ear aeration compared to the sCSFL cohort. LSBR of sCSFL does not appear to increase risk for developing chronic ear disease.
  • Neuroanatomic Correlates for the Neuropsychological Manifestations of Chiari Malformation Type I. [Journal Article]
    World Neurosurg. 2020 Apr; 136:462-469.Steinberg SN, Greenfield JP, Perrine K
  • Chiari malformation comprises a spectrum of congenital malformations characterized by a herniation of the cerebellar tonsils below the foramen magnum. Chiari malformation type I (CM-I) is the most prevalent subtype seen in clinical practice. This condition variably compresses the cerebellum and medulla-spinal cord junction secondary to malformation of the posterior fossa. Most neurologists and ne…
  • Persistent Syringomyelia After Posterior Fossa Decompression for Chiari Malformation. [Journal Article]
    World Neurosurg. 2020 Apr; 136:454-461.e1.Tosi U, Lara-Reyna J, … Greenfield JP
  • CONCLUSIONS: In this small cohort of unique patients, syrinx resolution was not achieved via decompression surgery. Despite "radiographic failure," good symptom control was achieved, with most patients remaining or becoming asymptomatic postoperatively, thus supporting our rationale for what has largely been a conservative approach in this population.
  • Ventrolateral Tonsillar Position Defines Novel Chiari 0.5 Classification. [Journal Article]
    World Neurosurg. 2020 Apr; 136:444-453.Morgenstern PF, Tosi U, … Greenfield JP
  • CONCLUSIONS: We define a novel Chiari entity, Chiari type 0.5 malformation, characterized by ventral tonsillar wrapping around the medulla in young children in the absence of classic Chiari type 1 malformation imaging findings. These patients are more likely to present with medullary symptoms than patients without VH. They are also more likely to require surgical decompression and respond favorably to intervention.
  • A case of successful surgical management of primary retroperitoneal mucinous cystadenoma. [Case Reports]
    J Surg Case Rep. 2020 Mar; 2020(3):rjaa045.Afzal Z, Stupalkowska W, … Davies RJ
  • Primary retroperitoneal mucinous cystadenoma (PRMC) is a rare tumour. It was first reported in 1965, and since then, less than 100 cases have been reported. It is cystic in nature and most commonly affects the female population. It becomes symptomatic in later stages due to its mass effect, making the diagnosis challenging in its early asymptomatic stage. We report a case of a 32-year-old female …
  • Nasofrontal dermoid cyst: rare presentation of a philtrum sinus. [Journal Article]
    Br J Oral Maxillofac Surg. 2020 Mar 19 [Online ahead of print]Donnell CC, McKeague KF, … Stenhouse J
  • Congenital midline nasal lesions are extremely rare, and nasal dermoids are their most common presentation. To the best of our knowledge, only two cases of a philtrum sinus with skull base extension have been reported previously. A 3-year-old boy presented to the maxillofacial department with a discharging upper lip sinus that had been present from birth. No other congenital abnormalities were re…
  • Livebirth after robotic-assisted live donor uterus transplantation. [Journal Article]
    Acta Obstet Gynecol Scand. 2020 Mar 20 [Online ahead of print]Brännström M, Dahm-Kähler P, … Bokström H
  • The proof-of-concept of uterus transplantation, as a treatment for absolute uterine factor infertility, came with the first livebirth after uterus transplantation, which took place in Sweden in 2014. This was after a live donor procedure, with laparotomy in both donor and recipient. In our second, ongoing trail we introduced robotic-assisted laparoscopic surgery of the donor to develop minimal in…
  • Application of Human Amniotic Membrane in Temporomandibular Joint Osteoarthritis. [Journal Article]
    J Craniofac Surg. 2020 Mar 17 [Online ahead of print]Lopez-Martos R, Martin-Lozano G, … Infante-Cossio P
  • Human amniotic membrane (HAM) has recently been used as an interpositional material to prevent ankylosis or primary re-ankylosis after temporomandibular joint (TMJ) arthroplasty. Here, the authors describe an unusual case of a 32-year-old woman who presented with a noninflammatory degenerative osteoarthritis of the TMJ in which a HAM was placed following a high condylar arthroplasty and discectom…
  • Facial fractures: classification and highlights for a useful report. [Review]
    Insights Imaging. 2020 Mar 19; 11(1):49.Gómez Roselló E, Quiles Granado AM, … Pedraza Gutiérrez S
  • In patients with facial trauma, multidetector computed tomography is the first-choice imaging test because it can detect and characterize even small fractures and their associated complications quickly and accurately. It has helped clinical management and surgical planning, so radiologists must communicate their findings to surgeons effectively. In Le Fort fractures, there is a breach between the…
  • The medial sural artery perforator (MSAP) flap: A versatile flap for lower extremity reconstruction. [Journal Article]
    Injury. 2020 Feb 12 [Online ahead of print]Al-Himdani S, Din A, … Khan U
  • CONCLUSIONS: The MSAP provides robust foot-and-ankle reconstruction, whilst permitting glide when over the knee. Patient satisfaction and functional outcomes are excellent with careful patient selection. Care should be taken to avoid compression or kinking of the large, thin walled veins as the most commonly observed complication was venous congestion. We advocate MSAP as a first choice flap for small-to-moderate foot, ankle or knee defects.
  • Cavernous Hemangioma of Temporalis Muscle: A Case Report. [Case Reports]
    World J Plast Surg. 2020 Jan; 9(1):99-102.Motazedian G, Khojasteh A, … Anbardar MH
  • Cavernous hemangioma is an encapsulated nodular mass composed of dilated, cavernous vascular space separated by connective tissue stroma. Flattened endothelial cells line the vascular spaces, which were filled with blood. Though hemangiomas are the mast common benign neoplasms seen in children, they rarely occur in adults. In the head and neck region, the masseter and trapezius muscles are most c…
  • Abdominal wall schwannoma: a case report. [Case Reports]
    Gastroenterol Hepatol Bed Bench. 2020 Winter; 13(1):95-100.Tarchouli M, Essarghini M, … Bounaim A
  • Schwannomas or neurilemmomas are benign and slow-growing tumors that arise exclusively from Schwann cells in peripheral nerve sheaths. These neoplasms theoretically can occur anywhere in the body, but they most frequently affect extremities, as well as head and neck region. However, their presentation in the abdominal wall is extremely rare and only few cases have been reported in the literature.…
