Objectives:To estimate normal linear dimensions and volume of spleen in Jordanians using ultrasonography, and to correlate splenic volume with age and body parameters: height, weight, body surface area (BSA), and body mass index (BMI).Methods:A prospective pilot study was conducted on 205 volunteers (115 males and 90 females) not known to have any conditions likely to be associated with splenomegaly. The study was performed at the Radiology Department, Jordanian University Hospital, Amman, Jordan, between December 2013 and August 2014. All linear dimensions of spleen were measured, and splenic volume (index) was calculated using the standard prolate ellipsoid formula (length × width × depth × 0.523). The splenic volume was then analyzed with age and body parameters using the Pearson’s correlation coefficient.Results:The mean (± SD) splenic dimensions were 10.72±1.37 cm in length, 7.40±1.52 cm in width, 4.40±1.47 cm in depth, and 184.15±79.56 cm3 in volume. Men had larger spleens than women (p<0.0001). Age had no significant effect on spleen volume (r=0.11, p=0.12). There was a significant moderate positive correlation (p<0.0001), using Pearson’s correlation coefficient, between the spleen volume, and other parameters (height, weight, BSA, and BMI), with correlation coefficients exceeding 0.3.Conclusion:A local reference of spleen dimensions was established with a different range of values reported previously.

The accessory navicular (AN) is an accessory ossicle anatomically located on the medial side of the foot, proximal to the navicular and continuous with the tibialis posterior tendon. It is occasionally a source of pain and local tenderness. Knowledge of the AN and its morphological variations can help identify the source of a patient's symptoms and prevent misinterpreting them as fractures. Foot radiographs from 1,240 patients who presented in two centers with chronic foot pain, or persistent pain developed after trauma, were retrospectively reviewed to determine the incidence and variations of the AN in relation to gender. The AN was found in 20.9% (259/1240). Among 259 feet with AN, Type 1 was identified in 25.4% (66/259), Type 2 in 42.4% (110/259) (20.0% (52/259) Type 2 A and 22.4% (58/259) Type 2B), and Type 3 in 32.0% (83/259). After 13 patients with incomplete medical records had been excluded, the remaining records showed that foot pain was associated with an AN in 10.6% of patients (26/246). In 1.2% of cases, two additional ossicles were found proximal to the navicular, possibly the result of multiple ossification centers that did not unite at the time of development. Patient symptomatology was related to the presence of an AN in 2% of patients with chronic foot pain. The AN could vary morphologically. Our data can enhance our diagnostic skills in detecting these ossicles. Clin. Anat. 30:436-444, 2017. © 2017 Wiley Periodicals, Inc.

In the majority of cases, the identification of AGs can be facilitated by their characteristic appearances: rounded or oval shaped, well-defined outlines and homogenous intensity. The presence of an adjacent cortical vein can be considered as an additional supportive element.

Objectives:To assess the prevalence and associations of mesenteric panniculitis (MP) using multi-detector CT (MDCT).Methods:This retrospective study included 4758 consecutive patients who underwent abdomino-pelvic MDCT between January 2012 and December 2014 at Jordan University Hospital, Amman, Jordan. Radiological database was searched for MP diagnosis and patients with suspected MP were re-evaluated by an experienced radiologist to confirm the diagnosis. Data on all patients with confirmed MP diagnosis were subsequently collected and analyzed.Results:Computed tomography features of MP were identified in 90 patients (41 males, 49 females), a prevalence of 1.9%. Mesenteric panniculitis was identified in both asymptomatic and symptomatic patients. Malignancy was found in 28 MP patients (31%) and 44 of the MP patients (49%) had prior history of abdomino-pelvic surgery. Mesenteric panniculitis was significantly more frequently associated with prior abdomino-pelvic surgery (p=0.0001) and the likelihood of associated malignancy in patients with MP was 2.1-fold higher than in patients without MP (p=0.0013).Conclusion:Mesenteric panniculitis can be reliably diagnosed by MDCT due to its typical CT appearance. Its identification is important because of its significant association with malignancy and because it represents one of the differential diagnoses in patients with nonspecific symptoms referred for abdomino-pelvic CT.

BACKGROUNDCervical intervertebral disc herniation can lead to myelopathy. Aging is an established variable related to spondylotic myelopathy. Studying this association will help in controlling the increase in spondylotic myelopathy with age.OBJECTIVESTo study the association between cervical disc level, its direction, and the frequency of myelopathy with age, and to assess the epidemiology of age-related cervical disc herniation and myelopathy.DESIGNRetrospective review of magnetic resonance (MR) images.SETTINGTertiary referral hospital.PATIENTS AND METHODSWe studied the MR images of adults patients (>18 years of age) referred to our department between 2001 and 2012 for suspected cervical spondylopathy. The direction and severity of herniation and the presence of myelopathy was determined for spinal levels C2 to C7.MAIN OUTCOME MEASURE(S)Relationship between age-related cervical disc herniation and myelopathy.RESULTSWe studied 6584 patient MR images, which included 2402 males (39.1%) and 3737 females (60.9%). The frequency of myelopathy increased with age from 0.6% in patients <20 years of age, reaching 9.1% in patients >70 years of age. The most common level affected by myelopathy was C5–C6. In elderly patients (>60 years), the C3–C4 level became the predominant level affected by myelopathy. Likewise, the frequency of central disc herniation increased significantly (P<.001) with age at all cervical levels. Furthermore, upper cervical levels showed a higher frequency of central disc herniation than lower cervical levels in the elderly.CONCLUSIONThe increased frequency of central disc herniation with age suggest an important, and probably a cause-effect relationship, between herniation and myelopathy.LIMITATIONSWe were unable to access clinical data or electrophysiological studies to correlate with MR image findings.

Prevalence of testicular microlithiasis of 5.3% in Jordanian patients is similar to what has been reported in the literature. Testicular microlithiasis does not have a significant effect on Doppler parameters of testicular arteries. The apparent impairment of sperm function in patients with testicular microlithiasis warrants further studies. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44:474-479, 2016.
