Usefulness of computed tomography during arteriography in a selective arterial calcium agent injection test for pancreatic gastrinoma: a case description

Background and PurposeBone mineral density (BMD) decreases rapidly with prolonged non–weight bearing. Maximizing the BMD response to reloading activities after NWB is critical to minimizing fracture risk. Methods for measuring individual tarsal and metatarsal BMD have not been available. This case report describes tarsal and metatarsal BMD with a reloading program, as revealed by quantitative computed tomography (QCT).Case DescriptionA 24-year-old woman was non–weight bearing for 6 weeks after right talocrural arthroscopy. Tarsal and metatarsal BMD were measured with QCT 9 weeks (before reloading) and 32 weeks (after reloading) after surgery. A 26-week progressive reloading program was completed. Change scores were calculated for BMD before reloading and BMD after reloading for the total foot (average of all tarsals and metatarsals), tarsals, metatarsals, bones of the medial column (calcaneus, navicular, cuneiforms 1 and 2, and metatarsal 1), and bones of the lateral column (calcaneus, cuboid, cuneiform 3, and metatarsals 2–5). The percent differences in BMD between the involved side and the uninvolved side were calculated.OutcomesBefore reloading, BMD of the involved total foot was 9% lower than that on the uninvolved side. After reloading, BMD increased 22% and 21% for the total foot, 16% and 14% for the tarsals, 29% and 30% for the metatarsals, 14% and 15% for the medial column bones, and 28% and 26% for the lateral column bones on the involved and uninvolved sides, respectively. After reloading, BMD of the involved total foot remained 8% lower than that on the uninvolved side.DiscussionThe increase in BMD with reloading was not uniform across all pedal bones; the metatarsals showed a greater increase than the tarsals, and the lateral column bones showed a greater increase than the medial column bones.

Tracheal Tumors

Background The majority of adult primary tracheal tumors are malignant; however, as one type of benign tumors, lipoma is extremely uncommon. Case Description We report a case where lipoma was first misdiagnosed as bronchial asthma, followed by sudden aggravation of dyspnea after trauma, and computed tomography (CT) examination of the neck and chest confirmed a tracheal tumor. Through multiple bronchoscopy interventions and placements of a tracheal stent, little therapeutic benefit was discovered, and resection of the tracheal tumor combined with tracheal end-to-end anastomosis was performed to ultimately achieve a cure. Conclusion Primary tracheal tumors should be highly suspected in patients with recurrent and gradually worsening dyspnea; timely cervical, thoracic CT and bronchoscopy can provide an accurate diagnosis. Surgical radical resection is the only way to cure all benign tracheal tumors such as lipoma.

Background Seed-type partial ossification of the ligamentum flavum (OLF) causing severe radiculopathy after rupture has not yet been described in the literature. Case Description A 51-year-old man presented with sudden onset severe back pain and right anterior thigh pain without any neurologic deficit after lifting a heavy weight. On preoperative computed tomography, we identified a ruptured seed-type partial OLF at the L1–L2 level. T2-weighted magnetic resonance sagittal and axial images showed thecal sac compression by the ruptured OLF. There was no improvement in his symptoms after 2 weeks of conservative management. The patient had percutaneous full endoscopic interlaminar removal of OLF. Postoperatively he experienced prompt improvement of his symptoms. Conclusion Rupture of seed-type partial OLF causing severe radiculopathy is extremely rare, and percutaneous endoscopy is a safe and effective alternative to open surgery in selected cases.

Dorsal Spinal

Background: Atlantoaxial pseudoarticulation rarely involves the cervical spine, and its etiology is unclear. In theory, pseudoarticulation is comparable to Bertolotti’s syndrome in the lumbar spine or may be attributed to an aberrant focal fusion between C0-C1-C2 that occurs during the gastrulation of embryologic development. Case Description: A 39-year-old female presented with neck pain and upper extremity weakness. Magnetic resonance/computed tomography studies documented a left-sided unilateral pseudoarticulation between the lamina of C1 and C2 causing compression of the dorsal spinal cord. Following resection of the accessory C1/C2 joint utilizing a C1 hemilaminectomy and partial C2 laminectomy, the patient’s neck pain and weakness resolved. Histologically, the tissue showed benign osteocartilaginous tissue with no synovial capsule. Conclusion: Here, the authors present a case of occiput-C1-C2 pseudojoint formation, leading to clinical and radiographic findings of cord compression due to boney outgrowth.

Background: Cerebellar mutism (CM) is a neurological condition characterized by lack of speech due to cerebellar lesions. Interruption of the bilateral dentatothalamocortical (DTC) pathways at midline structure seems the principal cause of CM but not fully understood. We described a rare case of CM due to heterochronic bilateral cerebellar hemorrhages. Case Description: An 87-year-old woman presented with depression of alertness after sudden vomiting. Neurologically, mild dysmetria and mutism were observed. The head computed tomography (CT) showed both a fresh right cerebellar hemorrhage and an obsolete left one. The patient was diagnosed as CM since both the thalamus and the supplementary motor area were bilaterally intact on both CT and magnetic resonance imaging. Medical treatment and rehabilitation improved her ataxia and ambulation. She became cognitively alert and could communicate by nodding, shaking her head, or facial expression. However, her mutism did not change at 4 months after the stroke. Conclusion: There are few reports on CM due to direct injuries to the bilateral dentate nuclei. Since our case did not show any injury other than bilateral dentate nuclei, this report can support the hypothesis that the interruptions of the bilateral DTC are the cause of CM.

Purpose. The aim of this paper is to report a case in which the cone beam computed tomography (CBCT) was important for the confirmation of the presence of mandibular atrophy and genial spines enlargement.Case Description. A 76-year-old female patient was referred for the assessment due to the complaint of chronic trauma in the anterior region of the floor of the mouth, which had been present for 2 months. CBCT images showed severe resorption of alveolar ridge and genial spines enlargement (5.5 mm × 12 mm).Conclusion. Accurate imaging assessment with the aid of 3D reconstructions allows the elimination of image superimposition and, therefore, plays an important role in the depiction of anatomical and pathological conditions, such as genial spines enlargement.

Background: “Kissing carotids” typically involves the lower C4-C6 retropharyngeal space. Here, we describe a case of “kissing carotids” observed at the C1-C2 level in conjunction with basilar invagination (BI). Case Description: A 34-year-old-male presented with congenital atlantoaxial dislocation and BI. The initial surgical plan was for a transoral decompression (TOD). However, this approach was abandoned when the preoperative computed tomography angiography (CTA) documented “kissing carotids” lying anteriorly at the C1-C2 level. Conclusion: Obtaining a CTA before performing a TOD for BI is essential to prevent an intraoperative catastrophic hemorrhage due to the laceration of “kissing carotids.”

Background. An upper and lower gastrointestinal (GI) series is an available and informative diagnostic test. Side effects are extremely rare. Objective. To present a case description of portal vein and liver barium embolism with a fatal outcome and explain the mechanism of its occurrence. Material and methods. The clinical manifestations, laboratory and instrumental findings, as well as autopsy of a female patient who died after lower GI radiography were analyzed. Results. To exclude intestinal obstruction, the patient underwent a barium follow through. Three days later, during X-ray computed tomography, barium and gas were detected in the inferior mesenteric vein, portal vein and its intrahepatic branches. During colonoscopy, diverticula of the sigmoid colon were detected, but the localization of the intestinalvenous fistula wasn’t determined. Conservative surgery failed and the death occurred 15 days after radiography. Conclusions. The autopsy revealed that the site of entry for the development of barium embolism as well as for gas, were diabrotic veins in peridiverticular abscesses localized in pericolic tissue.
