A case of atraumatic gluteal compartment syndrome complicated by sciatic nerve palsy and acute rhabdomyolysis is presented. A presumed diagnosis of deep venous thrombosis led to a delay in diagnosis. Gluteal compartment syndrome should be considered in the differential diagnosis of the swollen leg.

Chlorine nuclear resonance data for KCuCl3 have been used to show that no magnetic ordering occurs above 1.3°K, and that a low-lying excited state of the dimer Cu2Cl6= exists with ΔE / k ≈ 32°K if the ground state is a triplet or ΔE / k ≈ 48°K for a singlet ground state. The chlorine nuclear quadrupole coupling tensors have been determined at each of the three chemically inequivalent chlorine sites in Cu2Cl6=. A model which includes both ionic and covalent contributions to the quadrupole coupling tensor was used to explain the data and to estimate the charge distribution in the dimer. Observation of an EPR spectrum with g = 2.157 at 1.35°K and of the increase in the EPR intensity at 77°K compared to that at 300°K are evidence that the ground state of Cu2Cl6= is a triplet.

We present a case of a 42-year-old male with metastatic pleural encasement of the lung with extension into the mediastinum, resulting from an acinar adenocarcinoma of the submandibular gland diagnosed 30 years previously. The radiographic and CT appearances are presented, with a literature review.

W e read with great interest the recent article by Small et al, 1 "CTA Evaluation of Basilar Septations: An Entity Better Characterized as Aberrant Basilar Fenestrations," a retrospective review describing luminal abnormalities of the basilar artery. We wish to highlight a recent case at our institution that we believe constitutes an interesting example of a further variation in the luminal morphology of the basilar artery.A 71-year-old male patient presented with transient sensory disturbance of the right upper limb, clinically considered to be suggestive of a transient ischemic attack. The patient underwent noncontrast CT of the head, CT angiography of the head and neck, and subsequently MR imaging of the brain. Imaging did not demonstrate an acute infarct or vascular occlusion; however, note was made of abnormal morphology of the vertebrobasilar system with what was interpreted as a small communicating vessel joining the distal V4 segments of the vertebral arteries (Fig 1). It is possible, however, that this, in fact, represents a further transversely orientated variant of basilar fenestration morphology, not conforming directly to the classification described by Small et al. We have been unable to identify additional previously described examples of this in the literature. [2][3][4] Incidentally, the patient's imaging also demonstrated a right-sided persistent trigeminal artery (Fig 2).
