Neurology 2020 Jun 30. Epub 2020 Jun 30.

Department of Neurology, The Royal London Hospital, London, UK

A 57-year-old woman was admitted with a tonic-clonic seizure on a background of systemic sarcoidosis with uveitis and hilar lymphadenopathy. She had previously been well and stopped steroids one year before presentation. CT showed a sclerotic lesion with focal lucent areas in the skull base MRI revealed a frontal FLAIR hyperintense oedematous lesion with meningeal enhancement in gadolinium T1 This appearance on imaging evokes broad differential diagnoses such as sarcoidosis, fungal (although she had increasing lesion size despite six-month treatment with amphotericin B), craniofacial fibrous dysplasia, atypical lymphoma, nasopharyngeal carcinoma, myeloma and tuberculosis, therefore necessitating biopsy for definitive evaluation.

Clinical features and MRI characteristics of presumptive constrictive myelopathy in 27 pugs.

Vet Radiol Ultrasound 2020 Jun 25. Epub 2020 Jun 25.

Radiology Department, Willows Referral Centre, Solihull, UK.

Constrictive myelopathy has been described in pugs with paraparesis and is characterized by fibrous connective and granulation tissue within the dura mater causing spinal cord compression and focal gliosis. An association between constrictive myelopathy and caudal articular process (CAP) dysplasia is suspected; however, some studies have reported CAP dysplasia as an incidental finding. The imaging appearance of constrictive myelopathy is currently limited to a small number of cases. Read More

Bone Tumors: Benign Bone Tumors.

Authors:
Yee Lam

FP Essent 2020 Jun;493:11-21

UNC Department of Family Medicine, 590 Manning Drive, Chapel Hill, NC 27599.

Primary benign bone tumors are uncommon and most often affect children and young adults. They typically are detected incidentally on imaging, though some patients present with pain, swelling, or other symptoms. The four main categories of benign bone tumor are: bone-forming (eg, osteoid osteoma, osteoblastoma, fibrous dysplasia, enostosis), cartilage-forming (eg, osteochondroma, enchondroma), connective tissue, and vascular; the latter two are rare.

Superimposed mosaicism in tuberous sclerosis complex: a key to understanding all of the manifold manifestations?

Authors:
R Happle A Torrelo

J Eur Acad Dermatol Venereol 2020 May 12. Epub 2020 May 12.

Department. of Dermatology, Hospital Infantil Universitario Niño Jesús, Madrid, Spain.

In patients with tuberous sclerosis we can today distinguish between two different categories of segmental mosaicism. The well-known simple segmental mosaicism is characterized by a unilateral or otherwise localized arrangement of the ordinary lesions of the disorder, reflecting heterozygosity for an early postzygotic new mutation. By contrast, superimposed mosaicism is defined by a pronounced segmental involvement in a patient with ordinary nonsegmental lesions of the same disorder, resulting in a heterozygous embryo from loss of the corresponding wild-type allele that occurred at a very early developmental stage.

PET imaging of phosphodiesterase-4 identifies affected dysplastic bone in McCune-Albright syndrome, a genetic mosaic disorder.

J Nucl Med 2020 Apr 13. Epub 2020 Apr 13.

Skeletal Disorders and Mineral Homeostasis Section, National Institute of Dental and Craniofacial Research, United States.

McCune-Albright syndrome (MAS) is a mosaic disorder arising from gain-of-function mutations in the GNAS gene, which encodes the 3', 5'-cyclic adenosine monophosphate (cAMP) pathway-associated G-protein, Gsα. Clinical manifestations of MAS in a given individual, including fibrous dysplasia, are determined by the timing and location of the GNAS mutation during embryogenesis, the tissues involved, and the role of Gsα in the affected tissues. The Gsα mutation results in dysregulation of the cAMP signaling cascade, leading to upregulation of phosphodiesterase type 4 (PDE4), which catalyzes the hydrolysis of cAMP. Read More

Background: Classic "do not touch" and benign osseous lesions are sometimes detected on -F-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) studies. These lesions are often referred for biopsy because the physician interpreting the PET/CT may not be familiar with the spectrum of F-FDG uptake patterns that these lesions display.

Aim: To show that "do not touch" and benign osseous lesions can have increased F-FDG uptake above blood-pool on PET/CT; therefore, the CT appearance of these lesions should dictate management rather than the standardized uptake values (SUV). Read More

Best practice management guidelines for fibrous dysplasia/McCune-Albright syndrome: a consensus statement from the FD/MAS international consortium.

Orphanet J Rare Dis 2019 06 13;14(1):139. Epub 2019 Jun 13.

Skeletal Disorders and Mineral Homeostasis Section, National Institute of Dental and Craniofacial Research, Bethesda, MD, USA.

Fibrous Dysplasia / McCune Albright syndrome (FD/MAS) represents a wide spectrum of diseases due to somatic gain-of-function mutations of the GNAS gene. The mutation leads to overactivity in the target tissues and to a wide phenotype of clinical features that vary in severity and age of onset. The rarity of the disease and its variable presentation to multiple specialities often leads to misdiagnosis and inappropriate variability in investigations and treatments. Read More

A mixed radiopaque - radiolucent lesion in the anterior mandible associated with multiple impacted teeth: A radiodiagnostic challenge?

J Cancer Res Ther 2019 Jul-Sep;15(3):700-703

Department of Oral Pathology, A.J. Institute of Dental Sciences, Mangalore, Karnataka, India.

Desmoplastic ameloblastoma (DA) exhibits important differences in gender, anatomic distribution, radiographic findings, and histologic appearance compared to other types of ameloblastoma. Radiologically, DA is seen either as ill-defined mass containing osteolytic and sclerotic areas or as multifocal radiodense flecks within radiolucent background resembling a honeycomb. The radiographic differential diagnosis includes fibro-osseous lesions such as cemento-ossifying fibroma, fibrous dysplasia, calcifying odontogenic cyst, and chronic sclerosing osteomyelitis.
