A 49-year-old male was found unconscious at his accommodation and visited the emergency room. He was on antipsychotic and antidepressant drugs (vortioxetine hydrobromide, mirtazapine, sertraline hydrochloride, quetiapine, and alprazolam) for schizophrenia and major depression. At the time of discovery there were signs of overdose of the drugs around the patient. A physical examination revealed, pain, pallor, and edema in the left buttocks and lateral thigh. Active ankle movements below the left ankle were not possible and sensations in the tibia and peroneal nerves were lost. The pressure in the buttock compartment was measured at 42 mmHg. Magnetic resonance imaging revealed edema and high intensity signals in the left hip muscles and surrounding soft tissue. An emergency fasciotomy was performed and partial restoration of the lower extremity sensation and muscle strength were achieved after 24 hours.

A lumbar juxtafacet cyst is a rare disease that causes low back pain, radiculopathy and neurological claudication by compressing the nerve roots. A 34-year-old male complained of severe low back pain and radicular pain in the right lower extremity. Magnetic resonance images revealed a cyst at the lateral recess of the spinal canal between the L3-4 disc and posterior facet joint that extended to the L4 body level. Under the guidance of an image intensifier, needle aspiration of the cyst was performed, which extracted 1.5 ml of serous, yellowish colored fluid. After the aspiration, the symptoms subsided dramatically. The follow-up magnetic resonance images showed no recurrence of the cyst. To the best of the author’s knowledge, there are no reports of lumbar juxtafacet cyst treated with needle aspiration in Korea. This case is reported with a review of the relevant literature.

PURPOSE: The purpose of this study is to develop a simple method to measure magnetic susceptibility of arbitrarily shaped materials through MR imaging and numerical modeling. MATERIALS AND METHODS: Our 3D printed phantom consists of a lower compartment filled with a gel (gel part) and an upper compartment for placing a susceptibility object (object part). The B0 maps of the gel with and without the object were reconstructed from phase images obtained in a 3T MRI scanner. Then, their difference was compared with a numerically modeled B0 map based on the geometry of the object, obtained by a separate MRI scan of the object possibly immersed in an MR-visible liquid. The susceptibility of the object was determined by a least-squares fit. RESULTS: A total of 18 solid and liquid samples were tested, with measured susceptibility values in the range of −12.6 to 28.28 ppm. To confirm accuracy of the method, independently obtained reference values were compared with measured susceptibility when possible. The comparison revealed that our method can determine susceptibility within approximately 5%, likely limited by the object shape modeling error. CONCLUSION: The proposed gel-phantom-based susceptibility measurement may be used to effectively measure magnetic susceptibility of MR-compatible samples with an arbitrary shape, and can enable development of various MR engineering parts as well as test biological tissue specimens.

Uterine tumors resembling ovarian sex-cord tumors (UTROSCT) are very rare tumors that occur mainly in the uterine fundus of women in reproductive age. These tumors can be classified into group 1 and group 2 by histological results. In group 1, epithelial-like differentiation is partially observed in the tumors. In group 2, sex-cord elements are predominant in uterine mural mass. We experienced UTROSCT group 1 in a 29-year-old woman who complained of severe abdominal pain that started one week after delivery and UTROSCT group 2 case in a 49-year-old woman who complained of dysfunctional uterine bleeding. We report two different types of UTROSCT cases that we experienced.
