Hair follicle nevus of the abdominal skin: an unusual extracephalic presentation.

Jedrych J1, Akilov O, Gehris R, Ho J.Author information 1Department of Dermatology, School of Medicine, University of Pittsburgh, Pittsburgh, Pennsylvania.AbstractHair follicle nevus (HFN) is a rare hamartoma typically diagnosed on the face of infants, where it may clinically mimic an accessory tragus. We report a 6-month-old boy who presented with a congenital fleshy, bilobed papule in the midline of his upper abdomen that upon excision was classified as an HFN based on detailed histopathologic examination. Our report documents a previously undescribed extracephalic location of the HFN and therefore expands the spectrum of clinical presentations of this rare hamartoma.

Assessment of the Hepatic Veins in Poor Contrast Conditions using Dual Energy CT: Evaluation of a Novel Monoenergetic Extrapolation Software Algorithm.

Schabel C1, Bongers M1, Sedlmair M2, Korn A3, Grosse U1, Mangold S1, Claussen CD1, Thomas C1.Author information 1Department of Diagnostic and Interventional Radiology, University Hospital of Tuebingen.2Healthcare, Siemens AG, Forchheim.3Department of Diagnostic and Interventional Neuroradiology, University Hospital of Tuebingen.AbstractPurpose: To evaluate a novel monoenergetic post-processing algorithm (MEI+) in patients with poor intrahepatic contrast enhancement. Materials and Methods: 25 patients were retrospectively included in this study. Late-phase imaging of the upper abdomen, which was acquired in dual-energy mode (100/140 kV), was used as a model for poor intrahepatic contrast enhancement. Traditional monoenergetic images (MEI), linearly weighted mixed images with different mixing ratios (MI), sole 100 and 140 kV and MEI+ images were calculated. MEI+ is a novel technique which applies frequency-based mixing of the low keV images and an image of optimal keV from a noise perspective to combine the benefits of both image stacks. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the intrahepatic vasculature (IHV) and liver parenchyma (LP) were objectively measured and depiction of IHV was subjectively rated and correlated with portal venous imaging by two readers in consensus. Results: MEI+ was able to increase the SNR of the IHV (5.7 ± 0.4 at 40keV) and LP (4.9 ± 1.0 at 90keV) and CNR (2.1 ± 0.6 at 40keV) greatly compared to MEI (5.1 ± 1.1 at 80keV, 4.7 ± 1.0 at 80keV, 1.0 ± 0.4 at 70keV), MI (5.2 ± 1.1 M5:5, 4.8 ± 1.0 M5:5, 1.0 ± 3.5 M9:1), sole 100 kV images (4.4 ± 1.0, 3.7 ± 0.8, 1.0 ± 0.3) and 140 kV images (2.8 ± 0.5, 3.1 ± 0.6, 0.1 ± 0.2). Subjective assessment rated MEI+ of virtual 40 keV superior to all other images. Conclusion: MEI+ is a very promising algorithm for monoenergetic extrapolation which is able to overcome noise limitations associated with traditional monoenergetic techniques at low virtual keV levels and consequently does not suffer from a decline of SNR and CNR at low keV values. This algorithm allows an improvement of IHV depiction in the presence of poor contrast. Key points: • The evaluated new image-based algorithm for virtual monoenergetic imaging allows calculating low virtual keV images from dual energy datasets with significantly improved contrast-to-noise ratios. • The image based novel monoenergetic extrapolation algorithm applies frequency-based mixing of the low keV images and an image of optimal keV from a noise perspective to combine the benefits of both image stacks.• When compared to traditional monoenergetic images, the novel monoenergetic algorithm has improved contrast-to-noise ratios for both low and high virtual keV images.• Contrast-enhanced dual energy images with poor contrast conditions can be significantly improved, e.g. late phase imaging of the liver.

Solid pseudopapillary tumour of pancreas.

Singh A1, Agarwal AA, Sonkar AA, Kushwaha JK.Author information 1Department of Surgery, King George Medical University, Lucknow, Uttar Pradesh, India.AbstractSolid pseudopapillary tumour of the pancreas is a rare neoplasm (1%). This tumour primarily affects young women and is usually treated with surgical resection with a relatively favourable prognosis. We report an 18-year-old female patient presenting with moderate grade abdominal pain for 5 weeks. Abdominal examination revealed a lump palpable in the right upper abdomen. Contrast-enhanced CT abdomen reported soft tissue lesion arising from uncinate process of pancreas causing adjacent compression. Endoscopic ultrasound-guided fine-needle aspiration biopsy yielded a cellular sample comprising pseudopapillary arrangement with bland appearing tumour cells consistent with benign neoplasm. And because of unusual location, Whipple procedure was performed. The patient was discharged under satisfactory conditions. Final histology confirmed the diagnosis. Solid pseudopapillary tumours of the pancreas are a rare but treatable pancreatic tumour. Complete surgical excision is the treatment of choice and can be achieved through an open or minimal access technique.
