Carpal tunnel syndrome resulting from hydroxyapatite deposition.

Hydroxyapatite deposition disease (HADD) is a rare cause of carpal tunnel syndrome. This is a case report of a 55-year-old male who presented with symptoms of carpal tunnel syndrome and was subsequently found to have HADD. The diagnosis of HADD is made by the identification of poorly defined cloudy calcifications on radiography of the hand and wrist. Management is usually with nonsteroidal anti-inflammatory drugs, but if the pain is refractory, more invasive methods are utilized.

Infected dermoid sinus tract mimicking recurrent sinusitis in an adolescent male.

Nasal dermoid sinus cysts are the most common congenital midline nasofrontal masses, but they can easily be confused with simple recurrent sinusitis upon clinical presentation. We report the case of a 14-year-old male who was initially diagnosed with frontal sinusitis and treated with antibiotics but, after multiple episodes of recurrence, was later sent for imaging. Computed tomography and magnetic resonance imaging showed an infected dermoid sinus tract. Subsequent surgery removed the mass and pathologic investigation proved the diagnosis.

Neural fibrolipoma of the foot.

Neural fibrolipoma is a benign tumor comprised of hypertrophied fibrofatty tissue with intermixed nerve tissue. We present the case of a neural fibrolipoma of the foot that underwent above-ankle amputation and review the characteristic features of this unique form of localized gigantism.

Bare area of the glenoid: magnetic resonance appearance with arthroscopic correlation.

OBJECTIVE: To review the radiologic findings of a rarely reported focal area of acquired cartilage thinning located at the center of the glenoid fossa. METHODS: We retrospectively reviewed the medical records of 3 patients, each possessing a bare area of the glenoid detected on magnetic resonance (MR) imaging. A literature search was performed to obtain the most current information regarding this uncommon entity. RESULTS: Magnetic resonance imaging of the glenoid demonstrated a smoothly marginated subcentimeter area of thinning of the central articular cartilage containing hyperintense joint fluid or contrast in the case with MR arthrography. Arthroscopic correlation was obtained in a single case. CONCLUSIONS: The bare area of the glenoid is an acquired cartilage defect located at the center of the glenoid articular surface. Characteristic findings can be seen on MR imaging. Care should be taken not to mistake this acquired condition for posttraumatic defects of the glenoid articular cartilage.

Intervertebral disk cyst: a case report.

This case describes a patient who presented with chronic low back pain which developed over the course of 1 year. Imaging revealed a 1.1-cm cystic lesion at the L4-L5 vertebral level posterior to the intervertebral disk. Following both magnetic resonance and computed tomography imaging, diagnosis of intervertebral disk cyst was confirmed by both imaging modalities. A computed tomography-guided aspiration of the lesion was performed, and the patient was given a course of steroid injections with complete resolution of the lesion.
