Treatment of inferior vena cava (IVC) over-long segmental occlusion in Budd–Chiari syndrome (BCS) remains challenging. IVC segmental occlusion in BCS is often associated mainly with hepatic vein lesions in BCS, while the accessory hepatic vein (AHV) is typically patent and more intrahepatic collateral vessels are widely well-developed. Herein, we report our use of angioplasty for hepatic venous or the accessory hepatic vein for long segmental occlusion of the IVC in two BCS cases, rather than opening the IVC, in cases with a well-developed intrahepatic collateral.

This method provides satisfactory outcome in short follow-up period of 8 and 5 months respectively, and is practical and feasible.

We present the case of a 46-year-old woman with unremarkable medical history and a right palpable breast mass.

Standard mammograms revealed in the upper-outer quadrant of the right breast an opacity with imprecise delineation. The ultrasound showed a corresponding hypoechoic, irregular mass. An excision biopsy was performed. The initial pathology result indicated a possible lobular breast carcinoma or a lymphoma. Whole body computer tomography and regular blood workout were negative for a hematological malignancy.

Further immunohistochemistry tests shifted the diagnostic towards an acute myeloid leukemia (AML), not otherwise categorized.

The patient received specific chemotherapy and underwent an autologous stem cell transplantation with complete remission.

Acute myeloid leukemia may determine bilateral breast metastases, but it is extremely uncommon to generate a primary breast deposit.

A correct and early diagnostic is often problematic, “delays” or initial misdiagnosis being more frequent than rare in such cases. That is why, thorough investigations should follow whenever confronted with a mononuclear cell infiltrate within the breast.

Cerebral proliferative angiopathy (PA) is rare entity and is a clinical entity, which may be regarded as separate from cerebral AVMs in angioarchitecture, natural history, clinical presentation, and, therefore, treatment and which can be discerned from cerebral AVMs by characteristic imaging features, according to the 2008 “Stoke” paper published by Lasjaunias et al. We report a case of cerebral PA, which presented as a diffuse network of densely enhancing vascular spaces with intermingled normal brain parenchyma. The discrepancy between the large size of the nidus and the small shunting volume, the presence of diffuse angiogenesis, and the small calibre of a multitude of feeding arteries and draining veins were the angiographic hallmarks of this case. Cerebral PA should be considered in the differential diagnosis for cerebral AVMs that occur mostly in young female people.

Bifid mandibular condyle (BMC) is an uncommon condition with only few cases reported in the literature. Bilateral BMC is even more rare with an incidence one eighth that of unilateral BMC. Etiology of BMC is controversial, but two most common factors implicated include anomalous development and previous trauma. Association of BMC with temporomandibular joint (TMJ) ankylosis is exceptionally rare. We here report a case of bilateral bifid mandibular condyle with TMJ ankylosis in a 22 year old female with history of facial trauma six year prior to presentation.

Spinal vascular malformations are rare but complex entities. Non-invasive assessment and screening can be effectively performed with MRI/MRA. More recently, use of spinal CTA for characterization of these lesions is being reported. We describe, to our knowledge, the first report of dynamic assessment of a spinal vascular malformation with CT angiography of the spine using 320 detector imaging technique.

Hemangiopericytoma (HPC) is a tumor of the somatic soft tissues thought to be derived from pericytes. Hemagiopericytoma arising from bone is rare. We present a case of primary osseous HPC arising from the sacrum with characteristic imaging findings on CT and MR, as well as histopathologic findings. We also present findings on PET/CT imaging, which have not been previously published in the literature.

Brucellosis is a systemic inflammatory condition caused most commonly by Brucella Melitensis, a gram negative coccobacilli which is transmitted by infected animals and their products. Ondulent fever, night sweats and generalized weakness are the most common clinical symptoms but the wide spectrum of complaints can even include psychiatric disorders. We present a case who had neck stiffness and difficulty in neck movement as the initial complaints and radiologically, retropharyngeal soft tissue swelling at upper cervical level in MRI. This case report reveals the value of MRI in the further characterisation of pharyngeal involvement by brucellosis with an atypical presentation.
