Spontaneous talar and calcaneal fracture in rheumatoid arthritis: a case report by Antonio Spina et al. |
Published: 2011 July Issue: 5(7) :: Pages: 15-23
| Abstract: Rheumatoid arthritis (RA) leads to a progressive weakening of the skeleton which may result in bone fractures. However, spontaneous fractures (exclusive of stress fractures, vertebral collapse, and superficial articular fragmentation) in patients with rheumatoid arthritis have been only occasionally reported in the medical literature. A case of spontaneous talar and calcaneal fracture in rheumatoid arthritis is described. Bone lesions were identified on radiographs, MR images and scintigraphy in a patient with right ankle pain. The absence of episodes of acute trauma, and the presence of acute clinical manifestations should guide the clinical suspicion.

Retroperitoneal Fibrosis as a Cause of Positive FDG PET/CT by Amar Mehta et al. |
Published: 2011 July Issue: 5(7) :: Pages: 35-41
| Abstract: This article educates the reader on idiopathic retroperitoneal fibrosis and emphasizes the importance of considering conditions that mimic this disease on PET/CT through an illustrative case of a 58 year-old man presenting with intermittent abdominal, back, and scrotal pain undergoing successive PET/CT scans, both for diagnosis and following treatment.

Solid Pseudopapillary Tumor of the Pancreas: a rare and probably misdiagnosed neoplasm by Ana Frias Vilaça et al. |
Published: 2011 July Issue: 5(7) :: Pages: 24-34
| Abstract: Solid Pseudopapillary Tumor of the pancreas is a rare nonfunctioning tumor. It is considered a low-grade malignancy that is apparently curable with surgical complete excision in most instances. We present a case of solid pseudopapillary pancreatic tumor that represented a challenge to the radiologists. This case highlights its possible various appearances and the need to the radiologist to be familiar with them.

Accessory parotid gland with ectopic fistulous duct - Diagnosis by ultrasonography, digital fistulography, digital sialography and CT fistulography. A case report and review of current literature. by Chaitanya Dattatray Kulkarni et al. |
Published: 2011 July Issue: 5(7) :: Pages: 7-14
| Abstract: Accessory parotid glands are a common clinical occurrence and usually drain into the main Stenson`s duct by small ductules and thereby, into the buccal cavity. Presence of an accessory parotid gland with an ectopic fistulous duct is a rare occurrence. We present the imaging findings in a case of right accessory parotid gland with ectopic fistulous duct associated with bilateral pre-aural appendages. Diagnostic workup was done by ultrasonography, sono-fistulography, contrast digital fistulography, contrast digital sialography and computed tomography fistulography. Imaging showed a right accessory parotid gland lying anterior to and separate from the main parotid gland draining via an ectopic fistulous duct opening over the right cheek. The child was managed surgically by internalisation of the duct to open into the buccal mucosa and excision of pre-aural appendages.

Acrokeratosis paraneoplastica (Bazex syndrome): Report of a case associated with small cell lung carcinoma and review of the literature by Jessica G. Zarzour et al. |
Published: 2011 July Issue: 5(7) :: Pages: 1-6
| Abstract: Acrokeratosis paraneoplastic (Bazex syndrome) is a rare, but distinctive paraneoplastic dermatosis characterized by erythematosquamous lesions located at the acral sites and is most commonly associated with carcinomas of the upper aerodigestive tract. We report a 58-year-old female with a history of a pigmented rash on her extremities, thick keratotic plaques on her hands, and brittle nails. Chest imaging revealed a right upper lobe mass that was proven to be small cell lung carcinoma. While Bazex syndrome has been described in the dermatology literature, it is also important for the radiologist to be aware of this entity and its common presentations.
